# Contributing
1. Sign one of the contributor license agreements below.
1. `go get golang.org/x/review/git-codereview` to install the code reviewing
tool.
1. You will need to ensure that your `GOBIN` directory (by default
`$GOPATH/bin`) is in your `PATH` so that git can find the command.
1. If you would like, you may want to set up aliases for git-codereview,
such that `git codereview change` becomes `git change`. See the
[godoc](https://godoc.org/golang.org/x/review/git-codereview) for details.
1. Should you run into issues with the git-codereview tool, please note
that all error messages will assume that you have set up these aliases.
1. Get the cloud package by running `go get -d cloud.google.com/go`.
1. If you have already checked out the source, make sure that the remote
git origin is https://code.googlesource.com/gocloud:
```
git remote set-url origin https://code.googlesource.com/gocloud
```
1. Make sure your auth is configured correctly by visiting
https://code.googlesource.com, clicking "Generate Password", and following the
directions.
1. Make changes and create a change by running `git codereview change <name>`,
provide a commit message, and use `git codereview mail` to create a Gerrit CL.
1. Keep amending to the change with `git codereview change` and mail as your
receive feedback. Each new mailed amendment will create a new patch set for
your change in Gerrit.
- Note: if your change includes a breaking change, our breaking change
detector will cause CI/CD to fail. If your breaking change is acceptable
in some way, add BREAKING_CHANGE_ACCEPTABLE=<reason> to cause the
detector not to be run and to make it clear why that is acceptable.
## Integration Tests
In addition to the unit tests, you may run the integration test suite. These
directions describe setting up your environment to run integration tests for
_all_ packages: note that many of these instructions may be redundant if you
intend only to run integration tests on a single package.
#### GCP Setup
To run the integrations tests, creation and configuration of two projects in
the Google Developers Console is required: one specifically for Firestore
integration tests, and another for all other integration tests. We'll refer to
these projects as "general project" and "Firestore project".
After creating each project, you must [create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount)
for each project. Ensure the project-level **Owner**
[IAM role](console.cloud.google.com/iam-admin/iam/project) role is added to
each service account. During the creation of the service account, you should
download the JSON credential file for use later.
Next, ensure the following APIs are enabled in the general project:
- BigQuery API
- BigQuery Data Transfer API
- Cloud Dataproc API
- Cloud Dataproc Control API Private
- Cloud Datastore API
- Cloud Firestore API
- Cloud Key Management Service (KMS) API
- Cloud Natural Language API
- Cloud OS Login API
- Cloud Pub/Sub API
- Cloud Resource Manager API
- Cloud Spanner API
- Cloud Speech API
- Cloud Translation API
- Cloud Video Intelligence API
- Cloud Vision API
- Compute Engine API
- Compute Engine Instance Group Manager API
- Container Registry API
- Firebase Rules API
- Google Cloud APIs
- Google Cloud Deployment Manager V2 API
- Google Cloud SQL
- Google Cloud Storage
- Google Cloud Storage JSON API
- Google Compute Engine Instance Group Updater API
- Google Compute Engine Instance Groups API
- Kubernetes Engine API
- Stackdriver Error Reporting API
Next, create a Datastore database in the general project, and a Firestore
database in the Firestore project.
Finally, in the general project, create an API key for the translate API:
- Go to GCP Developer Console.
- Navigate to APIs & Services > Credentials.
- Click Create Credentials > API Key.
- Save this key for use in `GCLOUD_TESTS_API_KEY` as described below.
#### Local Setup
Once the two projects are created and configured, set the following environment
variables:
- `GCLOUD_TESTS_GOLANG_PROJECT_ID`: Developers Console project's ID (e.g.
bamboo-shift-455) for the general project.
- `GCLOUD_TESTS_GOLANG_KEY`: The path to the JSON key file of the general
project's service account.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID`: Developers Console project's ID
(e.g. doorway-cliff-677) for the Firestore project.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_KEY`: The path to the JSON key file of the
Firestore project's service account.
- `GCLOUD_TESTS_GOLANG_KEYRING`: The full name of the keyring for the tests,
in the form
"projects/P/locations/L/keyRings/R". The creation of this is described below.
- `GCLOUD_TESTS_API_KEY`: API key for using the Translate API.
- `GCLOUD_TESTS_GOLANG_ZONE`: Compute Engine zone.
Install the [gcloud command-line tool][gcloudcli] to your machine and use it to
create some resources used in integration tests.
From the project's root directory:
``` sh
# Sets the default project in your env.
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
# Authenticates the gcloud tool with your account.
$ gcloud auth login
# Create the indexes used in the datastore integration tests.
$ gcloud datastore indexes create datastore/testdata/index.yaml
# Creates a Google Cloud storage bucket with the same name as your test project,
# and with the Stackdriver Logging service account as owner, for the sink
# integration tests in logging.
$ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
$ gsutil acl ch -g cloud-logs@google.com:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
# Creates a PubSub topic for integration tests of storage notifications.
$ gcloud beta pubsub topics create go-storage-notification-test
# Next, go to the Pub/Sub dashboard in GCP console. Authorize the user
# "service-<numberic project id>@gs-project-accounts.iam.gserviceaccount.com"
# as a publisher to that topic.
# Creates a Spanner instance for the spanner integration tests.
$ gcloud beta spanner instances create go-integration-test --config regional-us-central1 --nodes 10 --description 'Instance for go client test'
# NOTE: Spanner instances are priced by the node-hour, so you may want to
# delete the instance after testing with 'gcloud beta spanner instances delete'.
$ export MY_KEYRING=some-keyring-name
$ export MY_LOCATION=global
# Creates a KMS keyring, in the same location as the default location for your
# project's buckets.
$ gcloud kms keyrings create $MY_KEYRING --location $MY_LOCATION
# Creates two keys in the keyring, named key1 and key2.
$ gcloud kms keys create key1 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
$ gcloud kms keys create key2 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
# Sets the GCLOUD_TESTS_GOLANG_KEYRING environment variable.
$ export GCLOUD_TESTS_GOLANG_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_LOCATION/keyRings/$MY_KEYRING
# Authorizes Google Cloud Storage to encrypt and decrypt using key1.
gsutil kms authorize -p $GCLOUD_TESTS_GOLANG_PROJECT_ID -k $GCLOUD_TESTS_GOLANG_KEYRING/cryptoKeys/key1
```
#### Running
Once you've done the necessary setup, you can run the integration tests by
running:
``` sh
$ go test -v cloud.google.com/go/...
```
#### Replay
Some packages can record the RPCs during integration tests to a file for
subsequent replay. To record, pass the `-record` flag to `go test`. The
recording will be saved to the _package_`.replay` file. To replay integration
tests from a saved recording, the replay file must be present, the `-short`
flag must be passed to `go test`, and the `GCLOUD_TESTS_GOLANG_ENABLE_REPLAY`
environment variable must have a non-empty value.

# How to Release this Repo
1. Determine the current release version with `git tag -l`. It should look
something like `vX.Y.Z`. We'll call the current version `$CV` and the new
version `$NV`.
1. On master, run `git log $CV..` to list all the changes since the last
release.
1. Edit `CHANGES.md` to include a summary of the changes.
1. `cd internal/version && go generate && cd -`
1. Mail the CL containing the `CHANGES.md` changes. When the CL is approved,
submit it.
1. Without submitting any other CLs:
a. Switch to master.
b. `git pull`
c. Tag the repo with the next version: `git tag $NV`.
d. Push the tag: `git push origin $NV`.

## TOML parser and encoder for Go with reflection
TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
reflection interface similar to Go's standard library `json` and `xml`
packages. This package also supports the `encoding.TextUnmarshaler` and
`encoding.TextMarshaler` interfaces so that you can define custom data
representations. (There is an example of this below.)
Spec: https://github.com/toml-lang/toml
Compatible with TOML version
[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
Documentation: https://godoc.org/github.com/BurntSushi/toml
Installation:
```bash
go get github.com/BurntSushi/toml
```
Try the toml validator:
```bash
go get github.com/BurntSushi/toml/cmd/tomlv
tomlv some-toml-file.toml
```
[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
### Testing
This package passes all tests in
[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
and the encoder.
### Examples
This package works similarly to how the Go standard library handles `XML`
and `JSON`. Namely, data is loaded into Go values via reflection.
For the simplest example, consider some TOML file as just a list of keys
and values:
```toml
Age = 25
Cats = [ "Cauchy", "Plato" ]
Pi = 3.14
Perfection = [ 6, 28, 496, 8128 ]
DOB = 1987-07-05T05:45:00Z
```
Which could be defined in Go as:
```go
type Config struct {
Age int
Cats []string
Pi float64
Perfection []int
DOB time.Time // requires `import time`
}
```
And then decoded with:
```go
var conf Config
if _, err := toml.Decode(tomlData, &conf); err != nil {
// handle error
}
```
You can also use struct tags if your struct field name doesn't map to a TOML
key value directly:
```toml
some_key_NAME = "wat"
```
```go
type TOML struct {
ObscureKey string `toml:"some_key_NAME"`
}
```
### Using the `encoding.TextUnmarshaler` interface
Here's an example that automatically parses duration strings into
`time.Duration` values:
```toml
[[song]]
name = "Thunder Road"
duration = "4m49s"
[[song]]
name = "Stairway to Heaven"
duration = "8m03s"
```
Which can be decoded with:
```go
type song struct {
Name string
Duration duration
}
type songs struct {
Song []song
}
var favorites songs
if _, err := toml.Decode(blob, &favorites); err != nil {
log.Fatal(err)
}
for _, s := range favorites.Song {
fmt.Printf("%s (%s)\n", s.Name, s.Duration)
}
```
And you'll also need a `duration` type that satisfies the
`encoding.TextUnmarshaler` interface:
```go
type duration struct {
time.Duration
}
func (d *duration) UnmarshalText(text []byte) error {
var err error
d.Duration, err = time.ParseDuration(string(text))
return err
}
```
### More complex usage
Here's an example of how to load the example from the official spec page:
```toml
# This is a TOML document. Boom.
title = "TOML Example"
[owner]
name = "Tom Preston-Werner"
organization = "GitHub"
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
dob = 1979-05-27T07:32:00Z # First class dates? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
# You can indent as you please. Tabs or spaces. TOML don't care.
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
# Line breaks are OK when inside arrays
hosts = [
"alpha",
"omega"
]
```
And the corresponding Go types are:
```go
type tomlConfig struct {
Title string
Owner ownerInfo
DB database `toml:"database"`
Servers map[string]server
Clients clients
}
type ownerInfo struct {
Name string
Org string `toml:"organization"`
Bio string
DOB time.Time
}
type database struct {
Server string
Ports []int
ConnMax int `toml:"connection_max"`
Enabled bool
}
type server struct {
IP string
DC string
}
type clients struct {
Data [][]interface{}
Hosts []string
}
```
Note that a case insensitive match will be tried if an exact match can't be
found.
A working example of the above can be found in `_examples/example.{go,toml}`.

// All other TOML types (float, string, int, bool and array) correspond

// (floats, strings, integers, booleans and datetimes) will be converted to
// a byte string and given to the value's UnmarshalText method. See the
// Unmarshaler example for a demonstration with time duration strings.
//
// Key mapping
//
// TOML keys can map to either keys in a Go map or field names in a Go
// struct. The special `toml` struct tag may be used to map TOML keys to
// struct fields that don't match the key name exactly. (See the example.)
// A case insensitive match to struct names will be tried if an exact match
// can't be found.
//
// The mapping between TOML values and Go values is loose. That is, there
// may exist TOML values that cannot be placed into your representation, and
// there may be parts of your representation that do not correspond to
// TOML values. This loose mapping can be made stricter by using the IsDefined
// and/or Undecoded methods on the MetaData returned.
//
// This decoder will not handle cyclic types. If a cyclic type is passed,
// `Decode` will not terminate.

/*
Package toml provides facilities for decoding and encoding TOML configuration
files via reflection. There is also support for delaying decoding with
the Primitive type, and querying the set of keys in a TOML document with the
MetaData type.
The specification implemented: https://github.com/toml-lang/toml
The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
whether a file is a valid TOML document. It can also be used to print the
type of each key in a TOML document.
Testing
There are two important types of tests used for this package. The first is
contained inside '*_test.go' files and uses the standard Go unit testing
framework. These tests are primarily devoted to holistically testing the
decoder and encoder.
The second type of testing is used to verify the implementation's adherence
to the TOML specification. These tests have been factored into their own
project: https://github.com/BurntSushi/toml-test
The reason the tests are in a separate project is so that they can be used by
any implementation of TOML. Namely, it is language agnostic.

go-gelf - GELF Library and Writer for Go
========================================
[GELF] (Graylog Extended Log Format) is an application-level logging
protocol that avoids many of the shortcomings of [syslog]. While it
can be run over any stream or datagram transport protocol, it has
special support ([chunking]) to allow long messages to be split over
multiple datagrams.
Versions
--------
In order to enable versionning of this package with Go, this project
is using GoPkg.in. The default branch of this project will be v1
for some time to prevent breaking clients. We encourage all project
to change their imports to the new GoPkg.in URIs as soon as possible.
To see up to date code, make sure to switch to the master branch.
v1.0.0
------
This implementation currently supports UDP and TCP as a transport
protocol. TLS is unsupported.
The library provides an API that applications can use to log messages
directly to a Graylog server and an `io.Writer` that can be used to
redirect the standard library's log messages (`os.Stdout`) to a
Graylog server.
[GELF]: http://docs.graylog.org/en/2.2/pages/gelf.html
[syslog]: https://tools.ietf.org/html/rfc5424
[chunking]: http://docs.graylog.org/en/2.2/pages/gelf.html#chunked-gelf
Installing
----------
go-gelf is go get-able:
go get gopkg.in/Graylog2/go-gelf.v1/gelf
or
go get github.com/Graylog2/go-gelf/gelf
This will get you version 1.0.0, with only UDP support and legacy API.
Newer versions are available through GoPkg.in:
go get gopkg.in/Graylog2/go-gelf.v2/gelf
Usage
-----
The easiest way to integrate graylog logging into your go app is by
having your `main` function (or even `init`) call `log.SetOutput()`.
By using an `io.MultiWriter`, we can log to both stdout and graylog -
giving us both centralized and local logs. (Redundancy is nice).
```golang
package main
import (
"flag"
"gopkg.in/Graylog2/go-gelf.v2/gelf"
"io"
"log"
"os"
)
func main() {
var graylogAddr string
flag.StringVar(&graylogAddr, "graylog", "", "graylog server addr")
flag.Parse()
if graylogAddr != "" {
// If using UDP
gelfWriter, err := gelf.NewUDPWriter(graylogAddr)
// If using TCP
//gelfWriter, err := gelf.NewTCPWriter(graylogAddr)
if err != nil {
log.Fatalf("gelf.NewWriter: %s", err)
}
// log to both stderr and graylog2
log.SetOutput(io.MultiWriter(os.Stderr, gelfWriter))
log.Printf("logging to stderr & graylog2@'%s'", graylogAddr)
}
// From here on out, any calls to log.Print* functions
// will appear on stdout, and be sent over UDP or TCP to the
// specified Graylog2 server.
log.Printf("Hello gray World")
// ...
}
```
The above program can be invoked as:
go run test.go -graylog=localhost:12201
When using UDP messages may be dropped or re-ordered. However, Graylog
server availability will not impact application performance; there is
a small, fixed overhead per log call regardless of whether the target
server is reachable or not.

# AWS SDK for Go
aws-sdk-go is the official AWS SDK for the Go programming language.
Checkout our [release notes](https://github.com/aws/aws-sdk-go/releases) for
information about the latest bug fixes, updates, and features added to the SDK.
We [announced](https://aws.amazon.com/blogs/developer/aws-sdk-for-go-2-0-developer-preview/) the Developer Preview for the [v2 AWS SDK for Go](https://github.com/aws/aws-sdk-go-v2). The v2 SDK source is available at https://github.com/aws/aws-sdk-go-v2, and add it to your project with `go get github.com/aws/aws-sdk-go-v2`. Check out the v2 SDK's [changes and updates](https://github.com/aws/aws-sdk-go-v2/blob/master/CHANGELOG.md), and let us know what you think. We want your feedback.
We have a pilot redesign of the [AWS SDK for Go API reference documentation](https://docs.aws.amazon.com/sdk-for-go/v1/api/gosdk-apiref.html). Let us know what you think.
## Installing
Use `go get` to retrieve the SDK to add it to your `GOPATH` workspace, or
project's Go module dependencies.
go get github.com/aws/aws-sdk-go
To update the SDK use `go get -u` to retrieve the latest version of the SDK.
go get -u github.com/aws/aws-sdk-go
### Dependencies
The SDK includes a `vendor` folder containing the runtime dependencies of the
SDK. The metadata of the SDK's dependencies can be found in the Go module file
`go.mod` or Dep file `Gopkg.toml`.
### Go Modules
If you are using Go modules, your `go get` will default to the latest tagged
release version of the SDK. To get a specific release version of the SDK use
`@<tag>` in your `go get` command.
go get github.com/aws/aws-sdk-go@v1.15.77
To get the latest SDK repository change use `@latest`.
go get github.com/aws/aws-sdk-go@latest
### Go 1.5
If you are using Go 1.5 without vendoring enabled, (`GO15VENDOREXPERIMENT=1`),
you will need to use `...` when retrieving the SDK to get its dependencies.
go get github.com/aws/aws-sdk-go/...
This will still include the `vendor` folder. The `vendor` folder can be deleted
if not used by your environment.
rm -rf $GOPATH/src/github.com/aws/aws-sdk-go/vendor
## Getting Help
Please use these community resources for getting help. We use the GitHub issues
for tracking bugs and feature requests.

## Opening Issues
If you encounter a bug with the AWS SDK for Go we would like to hear about it.
Search the [existing issues](https://github.com/aws/aws-sdk-go/issues) and see
if others are also experiencing the issue before opening a new issue. Please
include the version of AWS SDK for Go, Go language, and OS you’re using. Please
also include reproduction case when appropriate.
The GitHub issues are intended for bug reports and feature requests. For help
and questions with using AWS SDK for GO please make use of the resources listed
in the [Getting Help](https://github.com/aws/aws-sdk-go#getting-help) section.
Keeping the list of open issues lean will help us respond in a timely manner.
## Reference Documentation
[`Getting Started Guide`](https://aws.amazon.com/sdk-for-go/) - This document
is a general introduction on how to configure and make requests with the SDK.
If this is your first time using the SDK, this documentation and the API
documentation will help you get started. This document focuses on the syntax
and behavior of the SDK. The [Service Developer
Guide](https://aws.amazon.com/documentation/) will help you get started using
specific AWS services.
[`SDK API Reference
Documentation`](https://docs.aws.amazon.com/sdk-for-go/api/) - Use this
document to look up all API operation input and output parameters for AWS
services supported by the SDK. The API reference also includes documentation of
the SDK, and examples how to using the SDK, service client API operations, and
API operation require parameters.
[`Service Developer Guide`](https://aws.amazon.com/documentation/) - Use this
documentation to learn how to interface with AWS services. These guides are
great for getting started with a service, or when looking for more
information about a service. While this document is not required for coding,
services may supply helpful samples to look out for.
[`SDK Examples`](https://github.com/aws/aws-sdk-go/tree/master/example) -
Included in the SDK's repo are several hand crafted examples using the SDK
features and AWS services.
## Overview of SDK's Packages
The SDK is composed of two main components, SDK core, and service clients.
The SDK core packages are all available under the aws package at the root of
the SDK. Each client for a supported AWS service is available within its own
package under the service folder at the root of the SDK.
* aws - SDK core, provides common shared types such as Config, Logger,
and utilities to make working with API parameters easier.
* awserr - Provides the error interface that the SDK will use for all
errors that occur in the SDK's processing. This includes service API
response errors as well. The Error type is made up of a code and message.
Cast the SDK's returned error type to awserr.Error and call the Code
method to compare returned error to specific error codes. See the package's
documentation for additional values that can be extracted such as RequestID.
* credentials - Provides the types and built in credentials providers
the SDK will use to retrieve AWS credentials to make API requests with.
Nested under this folder are also additional credentials providers such as
stscreds for assuming IAM roles, and ec2rolecreds for EC2 Instance roles.
* endpoints - Provides the AWS Regions and Endpoints metadata for the SDK.
Use this to lookup AWS service endpoint information such as which services
are in a region, and what regions a service is in. Constants are also provided
for all region identifiers, e.g UsWest2RegionID for "us-west-2".
* session - Provides initial default configuration, and load
configuration from external sources such as environment and shared
credentials file.
* request - Provides the API request sending, and retry logic for the SDK.
This package also includes utilities for defining your own request
retryer, and configuring how the SDK processes the request.
* service - Clients for AWS services. All services supported by the SDK are
available under this folder.
## How to Use the SDK's AWS Service Clients
The SDK includes the Go types and utilities you can use to make requests to
AWS service APIs. Within the service folder at the root of the SDK you'll find
a package for each AWS service the SDK supports. All service clients follow common pattern of creation and usage.
When creating a client for an AWS service you'll first need to have a Session
value constructed. The Session provides shared configuration that can be shared
between your service clients. When service clients are created you can pass
in additional configuration via the aws.Config type to override configuration
provided by in the Session to create service client instances with custom
configuration.
Once the service's client is created you can use it to make API requests the
AWS service. These clients are safe to use concurrently.
## Configuring the SDK
In the AWS SDK for Go, you can configure settings for service clients, such
as the log level and maximum number of retries. Most settings are optional;
however, for each service client, you must specify a region and your credentials.
The SDK uses these values to send requests to the correct AWS region and sign
requests with the correct credentials. You can specify these values as part
of a session or as environment variables.
See the SDK's [configuration guide][config_guide] for more information.
See the [session][session_pkg] package documentation for more information on how to use Session
with the SDK.
See the [Config][config_typ] type in the [aws][aws_pkg] package for more information on configuration
options.

[config_typ]: https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config
[aws_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/
### Configuring Credentials
When using the SDK you'll generally need your AWS credentials to authenticate
with AWS services. The SDK supports multiple methods of supporting these
credentials. By default the SDK will source credentials automatically from
its default credential chain. See the session package for more information
on this chain, and how to configure it. The common items in the credential
chain are the following:
* Environment Credentials - Set of environment variables that are useful
when sub processes are created for specific roles.
* Shared Credentials file (~/.aws/credentials) - This file stores your
credentials based on a profile name and is useful for local development.
* EC2 Instance Role Credentials - Use EC2 Instance Role to assign credentials
to application running on an EC2 instance. This removes the need to manage
credential files in production.
Credentials can be configured in code as well by setting the Config's Credentials
value to a custom provider or using one of the providers included with the
SDK to bypass the default credential chain and use a custom one. This is
helpful when you want to instruct the SDK to only use a specific set of
credentials or providers.
This example creates a credential provider for assuming an IAM role, "myRoleARN"
and configures the S3 service client to use that role for API requests.
```go
// Initial credentials loaded from SDK's default credential chain. Such as
// the environment, shared credentials (~/.aws/credentials), or EC2 Instance
// Role. These credentials will be used to to make the STS Assume Role API.
sess := session.Must(session.NewSession())
// Create the credentials from AssumeRoleProvider to assume the role
// referenced by the "myRoleARN" ARN.
creds := stscreds.NewCredentials(sess, "myRoleArn")
// Create service client value configured for credentials
// from assumed role.
svc := s3.New(sess, &aws.Config{Credentials: creds})
```
See the [credentials][credentials_pkg] package documentation for more information on credential
providers included with the SDK, and how to customize the SDK's usage of
credentials.
The SDK has support for the shared configuration file (~/.aws/config). This
support can be enabled by setting the environment variable, "AWS_SDK_LOAD_CONFIG=1",
or enabling the feature in code when creating a Session via the
Option's SharedConfigState parameter.
```go
sess := session.Must(session.NewSessionWithOptions(session.Options{
SharedConfigState: session.SharedConfigEnable,
}))
```
[credentials_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/credentials
### Configuring AWS Region
In addition to the credentials you'll need to specify the region the SDK
will use to make AWS API requests to. In the SDK you can specify the region
either with an environment variable, or directly in code when a Session or
service client is created. The last value specified in code wins if the region
is specified multiple ways.
To set the region via the environment variable set the "AWS_REGION" to the
region you want to the SDK to use. Using this method to set the region will
allow you to run your application in multiple regions without needing additional
code in the application to select the region.
AWS_REGION=us-west-2
The endpoints package includes constants for all regions the SDK knows. The
values are all suffixed with RegionID. These values are helpful, because they
reduce the need to type the region string manually.
To set the region on a Session use the aws package's Config struct parameter
Region to the AWS region you want the service clients created from the session to
use. This is helpful when you want to create multiple service clients, and
all of the clients make API requests to the same region.
```go
sess := session.Must(session.NewSession(&aws.Config{
Region: aws.String(endpoints.UsWest2RegionID),
}))
```
See the [endpoints][endpoints_pkg] package for the AWS Regions and Endpoints metadata.
In addition to setting the region when creating a Session you can also set
the region on a per service client bases. This overrides the region of a
Session. This is helpful when you want to create service clients in specific
regions different from the Session's region.
```go
svc := s3.New(sess, &aws.Config{
Region: aws.String(endpoints.UsWest2RegionID),
})
```
See the [Config][config_typ] type in the [aws][aws_pkg] package for more information and additional
options such as setting the Endpoint, and other service client configuration options.
[endpoints_pkg]: https://docs.aws.amazon.com/sdk-for-go/api/aws/endpoints/
## Making API Requests
Once the client is created you can make an API request to the service.
Each API method takes a input parameter, and returns the service response
and an error. The SDK provides methods for making the API call in multiple ways.
In this list we'll use the S3 ListObjects API as an example for the different
ways of making API requests.
* ListObjects - Base API operation that will make the API request to the service.
* ListObjectsRequest - API methods suffixed with Request will construct the
API request, but not send it. This is also helpful when you want to get a
presigned URL for a request, and share the presigned URL instead of your
application making the request directly.
* ListObjectsPages - Same as the base API operation, but uses a callback to
automatically handle pagination of the API's response.
* ListObjectsWithContext - Same as base API operation, but adds support for
the Context pattern. This is helpful for controlling the canceling of in
flight requests. See the Go standard library context package for more
information. This method also takes request package's Option functional
options as the variadic argument for modifying how the request will be
made, or extracting information from the raw HTTP response.
* ListObjectsPagesWithContext - same as ListObjectsPages, but adds support for
the Context pattern. Similar to ListObjectsWithContext this method also
takes the request package's Option function option types as the variadic
argument.
In addition to the API operations the SDK also includes several higher level
methods that abstract checking for and waiting for an AWS resource to be in
a desired state. In this list we'll use WaitUntilBucketExists to demonstrate
the different forms of waiters.
* WaitUntilBucketExists. - Method to make API request to query an AWS service for
a resource's state. Will return successfully when that state is accomplished.
* WaitUntilBucketExistsWithContext - Same as WaitUntilBucketExists, but adds
support for the Context pattern. In addition these methods take request
package's WaiterOptions to configure the waiter, and how underlying request
will be made by the SDK.
The API method will document which error codes the service might return for
the operation. These errors will also be available as const strings prefixed
with "ErrCode" in the service client's package. If there are no errors listed
in the API's SDK documentation you'll need to consult the AWS service's API
documentation for the errors that could be returned.
```go
ctx := context.Background()
result, err := svc.GetObjectWithContext(ctx, &s3.GetObjectInput{
Bucket: aws.String("my-bucket"),
Key: aws.String("my-key"),
})
if err != nil {
// Cast err to awserr.Error to handle specific error codes.
aerr, ok := err.(awserr.Error)
if ok && aerr.Code() == s3.ErrCodeNoSuchKey {
// Specific error code handling
}
return err
}
// Make sure to close the body when done with it for S3 GetObject APIs or
// will leak connections.
defer result.Body.Close()
fmt.Println("Object Size:", aws.Int64Value(result.ContentLength))
```
### API Request Pagination and Resource Waiters
Pagination helper methods are suffixed with "Pages", and provide the
functionality needed to round trip API page requests. Pagination methods
take a callback function that will be called for each page of the API's response.
```go
objects := []string{}
err := svc.ListObjectsPagesWithContext(ctx, &s3.ListObjectsInput{
Bucket: aws.String(myBucket),
}, func(p *s3.ListObjectsOutput, lastPage bool) bool {
for _, o := range p.Contents {
objects = append(objects, aws.StringValue(o.Key))
}
return true // continue paging
})
if err != nil {
panic(fmt.Sprintf("failed to list objects for bucket, %s, %v", myBucket, err))
}
fmt.Println("Objects in bucket:", objects)
```
Waiter helper methods provide the functionality to wait for an AWS resource
state. These methods abstract the logic needed to check the state of an
AWS resource, and wait until that resource is in a desired state. The waiter
will block until the resource is in the state that is desired, an error occurs,
or the waiter times out. If a resource times out the error code returned will
be request.WaiterResourceNotReadyErrorCode.
```go
err := svc.WaitUntilBucketExistsWithContext(ctx, &s3.HeadBucketInput{
Bucket: aws.String(myBucket),
})
if err != nil {
aerr, ok := err.(awserr.Error)
if ok && aerr.Code() == request.WaiterResourceNotReadyErrorCode {
fmt.Fprintf(os.Stderr, "timed out while waiting for bucket to exist")
}
panic(fmt.Errorf("failed to wait for bucket to exist, %v", err))
}
fmt.Println("Bucket", myBucket, "exists")
```
## Complete SDK Example
This example shows a complete working Go file which will upload a file to S3
and use the Context pattern to implement timeout logic that will cancel the
request if it takes too long. This example highlights how to use sessions,
create a service client, make a request, handle the error, and process the
response.
```go
package main
import (
"context"
"flag"
"fmt"
"os"
"time"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/awserr"
"github.com/aws/aws-sdk-go/aws/request"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/aws/aws-sdk-go/service/s3"
)
// Uploads a file to S3 given a bucket and object key. Also takes a duration
// value to terminate the update if it doesn't complete within that time.
//
// The AWS Region needs to be provided in the AWS shared config or on the
// environment variable as `AWS_REGION`. Credentials also must be provided
// Will default to shared config file, but can load from environment if provided.
//
// Usage:
// # Upload myfile.txt to myBucket/myKey. Must complete within 10 minutes or will fail
// go run withContext.go -b mybucket -k myKey -d 10m < myfile.txt
func main() {
var bucket, key string
var timeout time.Duration
flag.StringVar(&bucket, "b", "", "Bucket name.")
flag.StringVar(&key, "k", "", "Object key name.")
flag.DurationVar(&timeout, "d", 0, "Upload timeout.")
flag.Parse()
// All clients require a Session. The Session provides the client with
// shared configuration such as region, endpoint, and credentials. A
// Session should be shared where possible to take advantage of
// configuration and credential caching. See the session package for
// more information.
sess := session.Must(session.NewSession())
// Create a new instance of the service's client with a Session.
// Optional aws.Config values can also be provided as variadic arguments
// to the New function. This option allows you to provide service
// specific configuration.
svc := s3.New(sess)
// Create a context with a timeout that will abort the upload if it takes
// more than the passed in timeout.
ctx := context.Background()
var cancelFn func()
if timeout > 0 {
ctx, cancelFn = context.WithTimeout(ctx, timeout)
}
// Ensure the context is canceled to prevent leaking.
// See context package for more information, https://golang.org/pkg/context/
if cancelFn != nil {
defer cancelFn()
}
// Uploads the object to S3. The Context will interrupt the request if the
// timeout expires.
_, err := svc.PutObjectWithContext(ctx, &s3.PutObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(key),
Body: os.Stdin,
})
if err != nil {
if aerr, ok := err.(awserr.Error); ok && aerr.Code() == request.CanceledErrorCode {
// If the SDK can determine the request or retry delay was canceled
// by a context the CanceledErrorCode error code will be returned.
fmt.Fprintf(os.Stderr, "upload canceled due to timeout, %v\n", err)
} else {
fmt.Fprintf(os.Stderr, "failed to upload object, %v\n", err)
}
os.Exit(1)
}
fmt.Printf("successfully uploaded file to %s/%s\n", bucket, key)
}
```

## AWS SDK for Go Private packages ##
`private` is a collection of packages used internally by the SDK, and is subject to have breaking changes. This package is not `internal` so that if you really need to use its functionality, and understand breaking changes will be made, you are able to.
These packages will be refactored in the future so that the API generator and model parsers are exposed cleanly on their own. Making it easier for you to generate your own code based on the API models.

Architecture of the library
===
ELF -> Specifications -> Objects -> Links
ELF
---
BPF is usually produced by using Clang to compile a subset of C. Clang outputs
an ELF file which contains program byte code (aka BPF), but also metadata for
maps used by the program. The metadata follows the conventions set by libbpf
shipped with the kernel. Certain ELF sections have special meaning
and contain structures defined by libbpf. Newer versions of clang emit
additional metadata in BPF Type Format (aka BTF).
The library aims to be compatible with libbpf so that moving from a C toolchain
to a Go one creates little friction. To that end, the [ELF reader](elf_reader.go)
is tested against the Linux selftests and avoids introducing custom behaviour
if possible.
The output of the ELF reader is a `CollectionSpec` which encodes
all of the information contained in the ELF in a form that is easy to work with
in Go.
### BTF
The BPF Type Format describes more than just the types used by a BPF program. It
includes debug aids like which source line corresponds to which instructions and
what global variables are used.
[BTF parsing](internal/btf/) lives in a separate internal package since exposing
it would mean an additional maintenance burden, and because the API still
has sharp corners. The most important concept is the `btf.Type` interface, which
also describes things that aren't really types like `.rodata` or `.bss` sections.
`btf.Type`s can form cyclical graphs, which can easily lead to infinite loops if
one is not careful. Hopefully a safe pattern to work with `btf.Type` emerges as
we write more code that deals with it.
Specifications
---
`CollectionSpec`, `ProgramSpec` and `MapSpec` are blueprints for in-kernel
objects and contain everything necessary to execute the relevant `bpf(2)`
syscalls. Since the ELF reader outputs a `CollectionSpec` it's possible to
modify clang-compiled BPF code, for example to rewrite constants. At the same
time the [asm](asm/) package provides an assembler that can be used to generate
`ProgramSpec` on the fly.
Creating a spec should never require any privileges or be restricted in any way,
for example by only allowing programs in native endianness. This ensures that
the library stays flexible.
Objects
---
`Program` and `Map` are the result of loading specs into the kernel. Sometimes
loading a spec will fail because the kernel is too old, or a feature is not
enabled. There are multiple ways the library deals with that:
* Fallback: older kernels don't allowing naming programs and maps. The library
automatically detects support for names, and omits them during load if
necessary. This works since name is primarily a debug aid.
* Sentinel error: sometimes it's possible to detect that a feature isn't available.
In that case the library will return an error wrapping `ErrNotSupported`.
This is also useful to skip tests that can't run on the current kernel.
Once program and map objects are loaded they expose the kernel's low-level API,
e.g. `NextKey`. Often this API is awkward to use in Go, so there are safer
wrappers on top of the low-level API, like `MapIterator`. The low-level API is
useful as an out when our higher-level API doesn't support a particular use case.
Links
---
BPF can be attached to many different points in the kernel and newer BPF hooks
tend to use bpf_link to do so. Older hooks unfortunately use a combination of
syscalls, netlink messages, etc. Adding support for a new link type should not
pull in large dependencies like netlink, so XDP programs or tracepoints are
out of scope.

# How to contribute
Development is on [GitHub](https://github.com/cilium/ebpf) and contributions in
the form of pull requests and issues reporting bugs or suggesting new features
are welcome. Please take a look at [the architecture](ARCHITECTURE.md) to get
a better understanding for the high-level goals.
New features must be accompanied by tests. Before starting work on any large
feature, please [join](https://cilium.herokuapp.com/) the
[#libbpf-go](https://cilium.slack.com/messages/libbpf-go) channel on Slack to
discuss the design first.
When submitting pull requests, consider writing details about what problem you
are solving and why the proposed approach solves that problem in commit messages
and/or pull request description to help future library users and maintainers to
reason about the proposed changes.
## Running the tests
Many of the tests require privileges to set resource limits and load eBPF code.
The easiest way to obtain these is to run the tests with `sudo`.
To test the current package with your local kernel you can simply run:
```
go test -exec sudo ./...
```
To test the current package with a different kernel version you can use the [run-tests.sh](run-tests.sh) script.
It requires [virtme](https://github.com/amluto/virtme) and qemu to be installed.
Examples:
```bash
# Run all tests on a 5.4 kernel
./run-tests.sh 5.4
# Run a subset of tests:
./run-tests.sh 5.4 go test ./link
```

- [uretprobe](uretprobe/) - Like a kprobe, but for symbols in userspace binaries (e.g. `bash`).
- [tracepoint](tracepoint/) - Attach a program to predetermined kernel tracepoints.
- Add your use case(s) here!
## How to run
```bash
cd ebpf/examples/
go run -exec sudo [./kprobe, ./uretprobe, ./tracepoint, ...]
```

# CFSSL
[![Build Status](https://travis-ci.org/cloudflare/cfssl.svg?branch=master)](https://travis-ci.org/cloudflare/cfssl)
[![Coverage Status](http://codecov.io/github/cloudflare/cfssl/coverage.svg?branch=master)](http://codecov.io/github/cloudflare/cfssl?branch=master)
[![GoDoc](https://godoc.org/github.com/cloudflare/cfssl?status.svg)](https://godoc.org/github.com/cloudflare/cfssl)
## CloudFlare's PKI/TLS toolkit
CFSSL is CloudFlare's PKI/TLS swiss army knife. It is both a command line
tool and an HTTP API server for signing, verifying, and bundling TLS
certificates. It requires Go 1.8+ to build.
Note that certain linux distributions have certain algorithms removed
(RHEL-based distributions in particular), so the golang from the
official repositories will not work. Users of these distributions should
[install go manually](//golang.org/dl) to install CFSSL.
CFSSL consists of:
* a set of packages useful for building custom TLS PKI tools
* the `cfssl` program, which is the canonical command line utility
using the CFSSL packages.
* the `multirootca` program, which is a certificate authority server
that can use multiple signing keys.
* the `mkbundle` program is used to build certificate pool bundles.
* the `cfssljson` program, which takes the JSON output from the
`cfssl` and `multirootca` programs and writes certificates, keys,
CSRs, and bundles to disk.
### Building
See [BUILDING](BUILDING.md)
### Installation
Installation requires a
[working Go 1.8+ installation](http://golang.org/doc/install) and a
properly set `GOPATH`.
```
$ go get -u github.com/cloudflare/cfssl/cmd/cfssl
```
will download and build the CFSSL tool, installing it in
`$GOPATH/bin/cfssl`.
To install any of the other utility programs that are
in this repo (for instance `cffsljson` in this case):
```
$ go get -u github.com/cloudflare/cfssl/cmd/cfssljson
```
This will download and build the CFSSLJSON tool, installing it in
`$GOPATH/bin/`.
And to simply install __all__ of the programs in this repo:
```
$ go get -u github.com/cloudflare/cfssl/cmd/...
```
This will download, build, and install all of the utility programs
(including `cfssl`, `cfssljson`, and `mkbundle` among others) into the
`$GOPATH/bin/` directory.
### Using the Command Line Tool
The `cfssl` command line tool takes a command to specify what
operation it should carry out:
sign signs a certificate
bundle build a certificate bundle
genkey generate a private key and a certificate request
gencert generate a private key and a certificate
serve start the API server
version prints out the current version
selfsign generates a self-signed certificate
print-defaults print default configurations
Use `cfssl [command] -help` to find out more about a command.
The `version` command takes no arguments.
#### Signing
```
cfssl sign [-ca cert] [-ca-key key] [-hostname comma,separated,hostnames] csr [subject]
```
The `csr` is the client's certificate request. The `-ca` and `-ca-key`
flags are the CA's certificate and private key, respectively. By
default, they are `ca.pem` and `ca_key.pem`. The `-hostname` is
a comma separated hostname list that overrides the DNS names and
IP address in the certificate SAN extension.
For example, assuming the CA's private key is in
`/etc/ssl/private/cfssl_key.pem` and the CA's certificate is in
`/etc/ssl/certs/cfssl.pem`, to sign the `cloudflare.pem` certificate
for cloudflare.com:
```
cfssl sign -ca /etc/ssl/certs/cfssl.pem \
-ca-key /etc/ssl/private/cfssl_key.pem \
-hostname cloudflare.com \
./cloudflare.pem
```
It is also possible to specify CSR with the `-csr` flag. By doing so,
flag values take precedence and will overwrite the argument.
The subject is an optional file that contains subject information that
should be used in place of the information from the CSR. It should be
a JSON file as follows:
```json
{
"CN": "example.com",
"names": [
{
"C": "US",
"L": "San Francisco",
"O": "Internet Widgets, Inc.",
"OU": "WWW",
"ST": "California"
}
]
}
```
**N.B.** As of Go 1.7, self-signed certificates will not include
[the AKI](https://go.googlesource.com/go/+/b623b71509b2d24df915d5bc68602e1c6edf38ca).
#### Bundling
```
cfssl bundle [-ca-bundle bundle] [-int-bundle bundle] \
[-metadata metadata_file] [-flavor bundle_flavor] \
-cert certificate_file [-key key_file]
```
The bundles are used for the root and intermediate certificate
pools. In addition, platform metadata is specified through `-metadata`.
The bundle files, metadata file (and auxiliary files) can be
found at:
https://github.com/cloudflare/cfssl_trust
Specify PEM-encoded client certificate and key through `-cert` and
`-key` respectively. If key is specified, the bundle will be built
and verified with the key. Otherwise the bundle will be built
without a private key. Instead of file path, use `-` for reading
certificate PEM from stdin. It is also acceptable that the certificate
file should contain a (partial) certificate bundle.
Specify bundling flavor through `-flavor`. There are three flavors:
`optimal` to generate a bundle of shortest chain and most advanced
cryptographic algorithms, `ubiquitous` to generate a bundle of most
widely acceptance across different browsers and OS platforms, and
`force` to find an acceptable bundle which is identical to the
content of the input certificate file.
Alternatively, the client certificate can be pulled directly from
a domain. It is also possible to connect to the remote address
through `-ip`.
```
cfssl bundle [-ca-bundle bundle] [-int-bundle bundle] \
[-metadata metadata_file] [-flavor bundle_flavor] \
-domain domain_name [-ip ip_address]
```
The bundle output form should follow the example:
```json
{
"bundle": "CERT_BUNDLE_IN_PEM",
"crt": "LEAF_CERT_IN_PEM",
"crl_support": true,
"expires": "2015-12-31T23:59:59Z",
"hostnames": ["example.com"],
"issuer": "ISSUER CERT SUBJECT",
"key": "KEY_IN_PEM",
"key_size": 2048,
"key_type": "2048-bit RSA",
"ocsp": ["http://ocsp.example-ca.com"],
"ocsp_support": true,
"root": "ROOT_CA_CERT_IN_PEM",
"signature": "SHA1WithRSA",
"subject": "LEAF CERT SUBJECT",
"status": {
"rebundled": false,
"expiring_SKIs": [],
"untrusted_root_stores": [],
"messages": [],
"code": 0
}
}
```
#### Generating certificate signing request and private key
```
cfssl genkey csr.json
```
To generate a private key and corresponding certificate request, specify
the key request as a JSON file. This file should follow the form:
```json
{
"hosts": [
"example.com",
"www.example.com"
],
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "US",
"L": "San Francisco",
"O": "Internet Widgets, Inc.",
"OU": "WWW",
"ST": "California"
}
]
}
```
#### Generating self-signed root CA certificate and private key
```
cfssl genkey -initca csr.json | cfssljson -bare ca
```
To generate a self-signed root CA certificate, specify the key request as
a JSON file in the same format as in 'genkey'. Three PEM-encoded entities
will appear in the output: the private key, the csr, and the self-signed
certificate.
#### Generating a remote-issued certificate and private key.
```
cfssl gencert -remote=remote_server [-hostname=comma,separated,hostnames] csr.json
```
This calls `genkey` but has a remote CFSSL server sign and issue
the certificate. You may use `-hostname` to override certificate SANs.
#### Generating a local-issued certificate and private key.
```
cfssl gencert -ca cert -ca-key key [-hostname=comma,separated,hostnames] csr.json
```
This generates and issues a certificate and private key from a local CA
via a JSON request. You may use `-hostname` to override certificate SANs.
#### Updating an OCSP responses file with a newly issued certificate
```
cfssl ocspsign -ca cert -responder key -responder-key key -cert cert \
| cfssljson -bare -stdout >> responses
```
This will generate an OCSP response for the `cert` and add it to the
`responses` file. You can then pass `responses` to `ocspserve` to start an
OCSP server.
### Starting the API Server
CFSSL comes with an HTTP-based API server; the endpoints are
documented in `doc/api/intro.txt`. The server is started with the `serve`
command:
```
cfssl serve [-address address] [-ca cert] [-ca-bundle bundle] \
[-ca-key key] [-int-bundle bundle] [-int-dir dir] [-port port] \
[-metadata file] [-remote remote_host] [-config config] \
[-responder cert] [-responder-key key] [-db-config db-config]
```
Address and port default to "127.0.0.1:8888". The `-ca` and `-ca-key`
arguments should be the PEM-encoded certificate and private key to use
for signing; by default, they are `ca.pem` and `ca_key.pem`. The
`-ca-bundle` and `-int-bundle` should be the certificate bundles used
for the root and intermediate certificate pools, respectively. These
default to `ca-bundle.crt` and `int-bundle.crt` respectively. If the
`-remote` option is specified, all signature operations will be forwarded
to the remote CFSSL.
`-int-dir` specifies an intermediates directory. `-metadata` is a file for
root certificate presence. The content of the file is a json dictionary
(k,v) such that each key k is an SHA-1 digest of a root certificate while value v
is a list of key store filenames. `-config` specifies a path to a configuration
file. `-responder` and `-responder-key` are the certificate and the
private key for the OCSP responder, respectively.
The amount of logging can be controlled with the `-loglevel` option. This
comes *after* the serve command:
```
cfssl serve -loglevel 2
```
The levels are:
* 0 - DEBUG
* 1 - INFO (this is the default level)
* 2 - WARNING
* 3 - ERROR
* 4 - CRITICAL
### The multirootca
The `cfssl` program can act as an online certificate authority, but it
only uses a single key. If multiple signing keys are needed, the
`multirootca` program can be used. It only provides the `sign`,
`authsign` and `info` endpoints. The documentation contains instructions
for configuring and running the CA.
### The mkbundle Utility
`mkbundle` is used to build the root and intermediate bundles used in
verifying certificates. It can be installed with
```
go get -u github.com/cloudflare/cfssl/cmd/mkbundle
```
It takes a collection of certificates, checks for CRL revocation (OCSP
support is planned for the next release) and expired certificates, and
bundles them into one file. It takes directories of certificates and
certificate files (which may contain multiple certificates). For example,
if the directory `intermediates` contains a number of intermediate
certificates:
```
mkbundle -f int-bundle.crt intermediates
```
will check those certificates and combine valid certificates into a single
`int-bundle.crt` file.
The `-f` flag specifies an output name; `-loglevel` specifies the verbosity
of the logging (using the same loglevels as above), and `-nw` controls the
number of revocation-checking workers.
### The cfssljson Utility
Most of the output from `cfssl` is in JSON. The `cfssljson` utility can take
this output and split it out into separate `key`, `certificate`, `CSR`, and
`bundle` files as appropriate. The tool takes a single flag, `-f`, that
specifies the input file, and an argument that specifies the base name for
the files produced. If the input filename is `-` (which is the default),
cfssljson reads from standard input. It maps keys in the JSON file to
filenames in the following way:
* if __cert__ or __certificate__ is specified, __basename.pem__ will be produced.
* if __key__ or __private_key__ is specified, __basename-key.pem__ will be produced.
* if __csr__ or __certificate_request__ is specified, __basename.csr__ will be produced.
* if __bundle__ is specified, __basename-bundle.pem__ will be produced.
* if __ocspResponse__ is specified, __basename-response.der__ will be produced.
Instead of saving to a file, you can pass `-stdout` to output the encoded
contents to standard output.
### Static Builds
By default, the web assets are accessed from disk, based on their
relative locations. If you wish to distribute a single,
statically-linked, `cfssl` binary, you’ll want to embed these resources
before building. This can by done with the
[go.rice](https://github.com/GeertJohan/go.rice) tool.
```
pushd cli/serve && rice embed-go && popd
```
Then building with `go build` will use the embedded resources.
### Using a PKCS#11 hardware token / HSM
For better security, you may wish to store your private key in an HSM or
smartcard. The interface to both of these categories of device is described by
the PKCS#11 spec. If you need to do approximately one signing operation per
second or fewer, the Yubikey NEO and NEO-n are inexpensive smartcard options:
https://www.yubico.com/products/yubikey-hardware/yubikey-neo/
In general you should look for a product that supports PIV (personal identity verification). If
your signing needs are in the hundreds of signatures per second, you will need
to purchase an expensive HSM (in the thousands to many thousands of USD).
If you wish to try out the PKCS#11 signing modes without a hardware token, you
can use the [SoftHSM](https://github.com/opendnssec/SoftHSMv1#softhsm)
implementation. Please note that using SoftHSM simply stores your private key in
a file on disk and does not increase security.
To get started with your PKCS#11 token you will need to initialize it with a
private key, PIN, and token label. The instructions to do this will be specific
to each hardware device, and you should follow the instructions provided by your
vendor. You will also need to find the path to your `module`, a shared object
file (.so). Having initialized your device, you can query it to check your token
label with:
pkcs11-tool --module <module path> --list-token-slots
You'll also want to check the label of the private key you imported (or
generated). Run the following command and look for a `Private Key Object`:
pkcs11-tool --module <module path> --pin <pin> \
--list-token-slots --login --list-objects
You now have all the information you need to use your PKCS#11 token with CFSSL.
CFSSL supports PKCS#11 for certificate signing and OCSP signing. To create a
Signer (for certificate signing), import `signer/universal` and call NewSigner
with a Root object containing the module, pin, token label and private label
from above, plus a path to your certificate. The structure of the Root object is
documented in `universal.go`.
Alternately, you can construct a pkcs11key.Key or pkcs11key.Pool yourself, and
pass it to ocsp.NewSigner (for OCSP) or local.NewSigner (for certificate
signing). This will be necessary, for example, if you are using a single-session
token like the Yubikey and need both OCSP signing and certificate signing at the
same time.

## containerd Adopters
A non-exhaustive list of containerd adopters is provided below.
**_Docker/Moby engine_** - Containerd began life prior to its CNCF adoption as a lower-layer
runtime manager for `runc` processes below the Docker engine. Continuing today, containerd
has extremely broad production usage as a component of the [Docker engine](https://github.com/docker/docker-ce)
stack. Note that this includes any use of the open source [Moby engine project](https://github.com/moby/moby);
including the Balena project listed below.
**_[IBM Cloud Kubernetes Service (IKS)](https://www.ibm.com/cloud/container-service)_** - offers containerd as the CRI runtime for v1.11 and higher versions.
**_[IBM Cloud Private (ICP)](https://www.ibm.com/cloud/private)_** - IBM's on-premises cloud offering has containerd as a "tech preview" CRI runtime for the Kubernetes offered within this product for the past two releases, and plans to fully migrate to containerd in a future release.
**_[Google Cloud Kubernetes Engine (GKE)](https://cloud.google.com/kubernetes-engine/)_** - offers containerd as the CRI runtime in **beta** for recent versions of Kubernetes.
**_[AWS Fargate](https://aws.amazon.com/fargate)_** - uses containerd + Firecracker (noted below) as the runtime and isolation technology for containers run in the Fargate platform. Fargate is a serverless, container-native compute offering from Amazon Web Services.
**_Cloud Foundry_** - The [Guardian container manager](https://github.com/cloudfoundry/guardian) for CF has been using OCI runC directly with additional code from CF managing the container image and filesystem interactions, but have recently migrated to use containerd as a replacement for the extra code they had written around runC.
**_Alibaba's PouchContainer_** - The Alibaba [PouchContainer](https://github.com/alibaba/pouch) project uses containerd as its runtime for a cloud native offering that has unique isolation and image distribution capabilities.
**_Rancher's k3s project_** - Rancher Labs [k3s](https://github.com/rancher/k3s) is a lightweight Kubernetes distribution; in their words: "Easy to install, half the memory, all in a binary less than 40mb." k8s uses containerd as the embedded runtime for this popular lightweight Kubernetes variant.
**_Rancher's Rio project_** - Rancher Labs [Rio](https://github.com/rancher/rio) project uses containerd as the runtime for a combined Kubernetes, Istio, and container "Cloud Native Container Distribution" platform.
**_Eliot_** - The [Eliot](https://github.com/ernoaapa/eliot) container project for IoT device container management uses containerd as the runtime.
**_Balena_** - Resin's [Balena](https://github.com/resin-os/balena) container engine, based on moby/moby but for edge, embedded, and IoT use cases, uses the containerd and runc stack in the same way that the Docker engine uses containerd.
**_LinuxKit_** - the Moby project's [LinuxKit](https://github.com/linuxkit/linuxkit) for building secure, minimal Linux OS images in a container-native model uses containerd as the core runtime for system and service containers.
**_BuildKit_** - The Moby project's [BuildKit](https://github.com/moby/buildkit) can use either runC or containerd as build execution backends for building container images. BuildKit support has also been built into the Docker engine in recent releases, making BuildKit provide the backend to the `docker build` command.
**_Azure acs-engine_** - Microsoft Azure's [acs-engine](https://github.com/Azure/acs-engine) open source project has customizable deployment of Kubernetes clusters, where containerd is a selectable container runtime. At some point in the future Azure's AKS service will default to use containerd as the CRI runtime for deployed Kubernetes clusters.
**_Amazon Firecracker_** - The AWS [Firecracker VMM project](http://firecracker-microvm.io/) has extended containerd with a new snapshotter and v2 shim to allow containerd to drive virtualized container processes via their VMM implementation. More details on their containerd integration are available in [their GitHub project](https://github.com/firecracker-microvm/firecracker-containerd).
**_Kata Containers_** - The [Kata containers](https://katacontainers.io/) lightweight-virtualized container runtime project integrates with containerd via a custom v2 shim implementation that drives the Kata container runtime.
**_D2iQ Konvoy_** - D2iQ Inc [Konvoy](https://d2iq.com/products/konvoy) product uses containerd as the container runtime for its Kubernetes distribution.
**_Inclavare Containers_** - [Inclavare Containers](https://github.com/alibaba/inclavare-containers) is an innovation of container runtime with the novel approach for launching protected containers in hardware-assisted Trusted Execution Environment (TEE) technology, aka Enclave, which can prevent the untrusted entity, such as Cloud Service Provider (CSP), from accessing the sensitive and confidential assets in use.
**_Other Projects_** - While the above list provides a cross-section of well known uses of containerd, the simplicity and clear API layer for containerd has inspired many smaller projects around providing simple container management platforms. Several examples of building higher layer functionality on top of the containerd base have come from various containerd community participants:
- Michael Crosby's [boss](https://github.com/crosbymichael/boss) project,
- Evan Hazlett's [stellar](https://github.com/ehazlett/stellar) project,
- Paul Knopf's immutable Linux image builder project: [darch](https://github.com/godarch/darch).

# Build containerd from source
This guide is useful if you intend to contribute on containerd. Thanks for your
effort. Every contribution is very appreciated.
This doc includes:
* [Build requirements](#build-requirements)
* [Build the development environment](#build-the-development-environment)
* [Build containerd](#build-containerd)
* [Via docker container](#via-docker-container)
* [Testing](#testing-containerd)
## Build requirements
To build the `containerd` daemon, and the `ctr` simple test client, the following build system dependencies are required:
* Go 1.13.x or above except 1.14.x
* Protoc 3.x compiler and headers (download at the [Google protobuf releases page](https://github.com/google/protobuf/releases))
* Btrfs headers and libraries for your distribution. Note that building the btrfs driver can be disabled via the build tag `no_btrfs`, removing this dependency.
## Build the development environment
First you need to setup your Go development environment. You can follow this
guideline [How to write go code](https://golang.org/doc/code.html) and at the
end you have `go` command in your `PATH`.
You need `git` to checkout the source code:
```sh
git clone https://github.com/containerd/containerd
```
For proper results, install the `protoc` release into `/usr/local` on your build system. For example, the following commands will download and install the 3.11.4 release for a 64-bit Linux host:
```
$ wget -c https://github.com/google/protobuf/releases/download/v3.11.4/protoc-3.11.4-linux-x86_64.zip
$ sudo unzip protoc-3.11.4-linux-x86_64.zip -d /usr/local
```
`containerd` uses [Btrfs](https://en.wikipedia.org/wiki/Btrfs) it means that you
need to satisfy these dependencies in your system:
* CentOS/Fedora: `yum install btrfs-progs-devel`
* Debian/Ubuntu: `apt-get install btrfs-progs libbtrfs-dev`
* Debian(before Buster)/Ubuntu(before 19.10): `apt-get install btrfs-tools`
At this point you are ready to build `containerd` yourself!
## Build runc
`runc` is the default container runtime used by `containerd` and is required to
run containerd. While it is okay to download a runc binary and install that on
the system, sometimes it is necessary to build runc directly when working with
container runtime development. You can skip this step if you already have the
correct version of `runc` installed.
`runc` requires `libseccomp`. You may need to install the missing dependencies:
* CentOS/Fedora: `yum install libseccomp libseccomp-devel`
* Debian/Ubuntu: `apt-get install libseccomp libseccomp-dev`
For the quick and dirty installation, you can use the following:
```
git clone https://github.com/opencontainers/runc
cd runc
make
sudo make install
```
Make sure to follow the guidelines for versioning in [RUNC.md](/docs/RUNC.md) for the
best results.
## Build containerd
`containerd` uses `make` to create a repeatable build flow. It means that you
can run:
```
cd containerd
make
```
This is going to build all the project binaries in the `./bin/` directory.
You can move them in your global path, `/usr/local/bin` with:
```sudo
sudo make install
```
When making any changes to the gRPC API, you can use the installed `protoc`
compiler to regenerate the API generated code packages with:
```sudo
make generate
```
> *Note*: Several build tags are currently available:
> * `no_btrfs`: A build tag disables building the btrfs snapshot driver.
> * `no_cri`: A build tag disables building Kubernetes [CRI](http://blog.kubernetes.io/2016/12/container-runtime-interface-cri-in-kubernetes.html) support into containerd.
> See [here](https://github.com/containerd/cri-containerd#build-tags) for build tags of CRI plugin.
> * `no_devmapper`: A build tag disables building the device mapper snapshot driver.
>
> For example, adding `BUILDTAGS=no_btrfs` to your environment before calling the **binaries**
> Makefile target will disable the btrfs driver within the containerd Go build.
Vendoring of external imports uses the [Go Modules](https://golang.org/ref/mod#vendoring). You need
to use `go mod` command to modify the dependencies. After modifition, you should run `go mod tidy`
and `go mod vendor` to ensure the `go.mod`, `go.sum` files and `vendor` directory are up to date.
Changes to these files should become a single commit for a PR which relies on vendored updates.
Please refer to [RUNC.md](/docs/RUNC.md) for the currently supported version of `runc` that is used by containerd.
### Static binaries
You can build static binaries by providing a few variables to `make`:
```sudo
make EXTRA_FLAGS="-buildmode pie" \
EXTRA_LDFLAGS='-linkmode external -extldflags "-fno-PIC -static"' \
BUILDTAGS="netgo osusergo static_build"
```
> *Note*:
> - static build is discouraged
> - static containerd binary does not support loading shared object plugins (`*.so`)
# Via Docker container
The following instructions assume you are at the parent directory of containerd source directory.
## Build containerd
You can build `containerd` via a Linux-based Docker container.
You can build an image from this `Dockerfile`:
```
FROM golang
RUN apt-get update && \
apt-get install -y libbtrfs-dev
```
Let's suppose that you built an image called `containerd/build`. From the
containerd source root directory you can run the following command:
```sh
docker run -it \
-v ${PWD}/containerd:/go/src/github.com/containerd/containerd \
-e GOPATH=/go \
-w /go/src/github.com/containerd/containerd containerd/build sh
```
This mounts `containerd` repository
You are now ready to [build](#build-containerd):
```sh
make && make install
```
## Build containerd and runc
To have complete core container runtime, you will need both `containerd` and `runc`. It is possible to build both of these via Docker container.
You can use `git` to checkout `runc`:
```sh
git clone https://github.com/opencontainers/runc
```
We can build an image from this `Dockerfile`:
```sh
FROM golang
RUN apt-get update && \
apt-get install -y libbtrfs-dev libseccomp-dev
```
In our Docker container we will build `runc` build, which includes
[seccomp](https://en.wikipedia.org/wiki/seccomp), [SELinux](https://en.wikipedia.org/wiki/Security-Enhanced_Linux),
and [AppArmor](https://en.wikipedia.org/wiki/AppArmor) support. Seccomp support
in runc requires `libseccomp-dev` as a dependency (AppArmor and SELinux support
do not require external libraries at build time). Refer to [RUNC.md](docs/RUNC.md)
in the docs directory to for details about building runc, and to learn about
supported versions of `runc` as used by containerd.
Let's suppose you build an image called `containerd/build` from the above Dockerfile. You can run the following command:
```sh
docker run -it --privileged \
-v /var/lib/containerd \
-v ${PWD}/runc:/go/src/github.com/opencontainers/runc \
-v ${PWD}/containerd:/go/src/github.com/containerd/containerd \
-e GOPATH=/go \
-w /go/src/github.com/containerd/containerd containerd/build sh
```
This mounts both `runc` and `containerd` repositories in our Docker container.
From within our Docker container let's build `containerd`:
```sh
cd /go/src/github.com/containerd/containerd
make && make install
```
These binaries can be found in the `./bin` directory in your host.
`make install` will move the binaries in your `$PATH`.
Next, let's build `runc`:
```sh
cd /go/src/github.com/opencontainers/runc
make && make install
```
For further details about building runc, refer to [RUNC.md](docs/RUNC.md) in the
docs directory.
When working with `ctr`, the simple test client we just built, don't forget to start the daemon!
```sh
containerd --config config.toml
```
# Testing containerd
During the automated CI the unit tests and integration tests are run as part of the PR validation. As a developer you can run these tests locally by using any of the following `Makefile` targets:
- `make test`: run all non-integration tests that do not require `root` privileges
- `make root-test`: run all non-integration tests which require `root`
- `make integration`: run all tests, including integration tests and those which require `root`. `TESTFLAGS_PARALLEL` can be used to control parallelism. For example, `TESTFLAGS_PARALLEL=1 make integration` will lead a non-parallel execution. The default value of `TESTFLAGS_PARALLEL` is **8**.
To execute a specific test or set of tests you can use the `go test` capabilities
without using the `Makefile` targets. The following examples show how to specify a test
name and also how to use the flag directly against `go test` to run root-requiring tests.
```sh
# run the test <TEST_NAME>:
go test -v -run "<TEST_NAME>" .
# enable the root-requiring tests:
go test -v -run . -test.root
```
Example output from directly running `go test` to execute the `TestContainerList` test:
```sh
sudo go test -v -run "TestContainerList" . -test.root
INFO[0000] running tests against containerd revision=f2ae8a020a985a8d9862c9eb5ab66902c2888361 version=v1.0.0-beta.2-49-gf2ae8a0
=== RUN TestContainerList
--- PASS: TestContainerList (0.00s)
PASS
ok github.com/containerd/containerd 4.778s
```
## Additional tools
### containerd-stress
In addition to `go test`-based testing executed via the `Makefile` targets, the `containerd-stress` tool is available and built with the `all` or `binaries` targets and installed during `make install`.
With this tool you can stress a running containerd daemon for a specified period of time, selecting a concurrency level to generate stress against the daemon. The following command is an example of having five workers running for two hours against a default containerd gRPC socket address:
```sh
containerd-stress -c 5 -t 120
```
For more information on this tool's options please run `containerd-stress --help`.
### bucketbench
[Bucketbench](https://github.com/estesp/bucketbench) is an external tool which can be used to drive load against a container runtime, specifying a particular set of lifecycle operations to run with a specified amount of concurrency. Bucketbench is more focused on generating performance details than simply inducing load against containerd.
Bucketbench differs from the `containerd-stress` tool in a few ways:
- Bucketbench has support for testing the Docker engine, the `runc` binary, and containerd 0.2.x (via `ctr`) and 1.0 (via the client library) branches.
- Bucketbench is driven via configuration file that allows specifying a list of lifecycle operations to execute. This can be used to generate detailed statistics per-command (e.g. start, stop, pause, delete).
- Bucketbench generates detailed reports and timing data at the end of the configured test run.
More details on how to install and run `bucketbench` are available at the [GitHub project page](https://github.com/estesp/bucketbench).
