# docker-build: build your software with docker
## Description
docker-build is a script to build docker images from source. It will be deprecated once the 'build' feature is incorporated into docker itself (See https://github.com/dotcloud/docker/issues/278)
Author: Solomon Hykes <solomon@dotcloud.com>
## Install
docker-builder requires:
1) A reasonably recent Python setup (tested on 2.7.2).
2) A running docker daemon at version 0.1.4 or more recent (http://www.docker.io/gettingstarted)
## Usage
First create a valid Changefile, which defines a sequence of changes to apply to a base image.
$ cat Changefile
# Start build from a know base image
from base:ubuntu-12.10
# Update ubuntu sources
run echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
run apt-get update
# Install system packages
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q git
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
run DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
# Insert files from the host (./myscript must be present in the current directory)
copy myscript /usr/local/bin/myscript
Run docker-build, and pass the contents of your Changefile as standard input.
$ IMG=$(./docker-build < Changefile)
This will take a while: for each line of the changefile, docker-build will:
1. Create a new container to execute the given command or insert the given file
2. Wait for the container to complete execution
3. Commit the resulting changes as a new image
4. Use the resulting image as the input of the next step
If all the steps succeed, the result will be an image containing the combined results of each build step.
You can trace back those build steps by inspecting the image's history:
$ docker history $IMG
ID CREATED CREATED BY
1e9e2045de86 A few seconds ago /bin/sh -c cat > /usr/local/bin/myscript; chmod +x /usr/local/bin/git
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
77db140aa62a A few seconds ago /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q git
83e85d155451 A few seconds ago /bin/sh -c apt-get update
bfd53b36d9d3 A few seconds ago /bin/sh -c echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
base 2 weeks ago /bin/bash
27cf78414709 2 weeks ago
Note that your build started from 'base', as instructed by your Changefile. But that base image itself seems to have been built in 2 steps - hence the extra step in the history.
You can use this build technique to create any image you want: a database, a web application, or anything else that can be build by a sequence of unix commands - in other words, anything else.

# Docker principles
In the design and development of Docker we try to follow these principles:
(Work in progress)
* Don't try to replace every tool. Instead, be an ingredient to improve them.
* When hesitating between 2 options, choose the one that is easier to reverse.
* No is temporary, Yes is forever. If you're not sure about a new feature, say no. You can change your mind later.
* Containers must be portable to the greatest possible number of machines. Be suspicious of any change which makes machines less interchangeable.
* The less moving parts in a container, the better.
* Don't merge it unless you document it.
* Don't document it unless you can keep it up-to-date.
* Don't merge it unless you test it!
* Everyone's problem is slightly different. Focus on the part that is the same for everyone, and solve that.

# Docker: what's next?
This document is a high-level overview of where we want to take Docker next.
It is a curated selection of planned improvements which are either important, difficult, or both.
For a more complete view of planned and requested improvements, see [the Github issues](https://github.com/dotcloud/docker/issues).
Tu suggest changes to the roadmap, including additions, please write the change as if it were already in effect, and make a pull request.
Broader kernel support
----------------------
Our goal is to make Docker run everywhere, but currently Docker requires [Linux version 3.8 or higher with lxc and aufs support](http://docs.docker.io/en/latest/installation/kernel.html). If you're deploying new machines for the purpose of running Docker, this is a fairly easy requirement to meet.
However, if you're adding Docker to an existing deployment, you may not have the flexibility to update and patch the kernel.
Expanding Docker's kernel support is a priority. This includes running on older kernel versions,
but also on kernels with no AUFS support, or with incomplete lxc capabilities.
Cross-architecture support
--------------------------
Our goal is to make Docker run everywhere. However currently Docker only runs on x86_64 systems.
We plan on expanding architecture support, so that Docker containers can be created and used on more architectures.
Even more integrations
----------------------
We want Docker to be the secret ingredient that makes your existing tools more awesome.
Thanks to this philosophy, Docker has already been integrated with
[Puppet](http://forge.puppetlabs.com/garethr/docker), [Chef](http://www.opscode.com/chef),
[Openstack Nova](https://github.com/dotcloud/openstack-docker), [Jenkins](https://github.com/georgebashi/jenkins-docker-plugin),
[DotCloud sandbox](http://github.com/dotcloud/sandbox), [Pallet](https://github.com/pallet/pallet-docker),
[Strider CI](http://blog.frozenridge.co/next-generation-continuous-integration-deployment-with-dotclouds-docker-and-strider/)
and even [Heroku buildpacks](https://github.com/progrium/buildstep).
Expect Docker to integrate with even more of your favorite tools going forward, including:
* Alternative storage backends such as ZFS, LVM or [BTRFS](github.com/dotcloud/docker/issues/443)
* Alternative containerization backends such as [OpenVZ](http://openvz.org), Solaris Zones, BSD Jails and even plain Chroot.
* Process managers like [Supervisord](http://supervisord.org/), [Runit](http://smarden.org/runit/), [Gaffer](https://gaffer.readthedocs.org/en/latest/#gaffer) and [Systemd](http://www.freedesktop.org/wiki/Software/systemd/)
* Build and integration tools like Make, Maven, Scons, Jenkins, Buildbot and Cruise Control.
* Configuration management tools like [Puppet](http://puppetlabs.com), [Chef](http://www.opscode.com/chef/) and [Salt](http://saltstack.org)
* Personal development environments like [Vagrant](http://vagrantup.com), [Boxen](http://boxen.github.com/), [Koding](http://koding.com) and [Cloud9](http://c9.io).
* Orchestration tools like [Zookeeper](http://zookeeper.apache.org/), [Mesos](http://incubator.apache.org/mesos/) and [Galaxy](https://github.com/ning/galaxy)
* Infrastructure deployment tools like [Openstack](http://openstack.org), [Apache Cloudstack](http://apache.cloudstack.org), [Ganeti](https://code.google.com/p/ganeti/)
Plugin API
----------
We want Docker to run everywhere, and to integrate with every devops tool.
Those are ambitious goals, and the only way to reach them is with the Docker community.
For the community to participate fully, we need an API which allows Docker to be deeply and easily customized.
We are working on a plugin API which will make Docker very, very customization-friendly.
We believe it will facilitate the integrations listed above - and many more we didn't even think about.
Let us know if you want to start playing with the API before it's generally available.
Externally mounted volumes
--------------------------
In 0.3 we [introduced data volumes](https://github.com/dotcloud/docker/wiki/Docker-0.3.0-release-note%2C-May-6-2013#data-volumes),
a great mechanism for manipulating persistent data such as database files, log files, etc.
Data volumes can be shared between containers, a powerful capability [which allows many advanced use cases](http://docs.docker.io/en/latest/examples/couchdb_data_volumes.html). In the future it will also be possible to share volumes between a container and the underlying host. This will make certain scenarios much easier, such as using a high-performance storage backend for your production database,
making live development changes available to a container, etc.
Better documentation
--------------------
We believe that great documentation is worth 10 features. We are often told that "Docker's documentation is great for a 2-month old project".
Our goal is to make it great, period.
If you have feedback on how to improve our documentation, please get in touch by replying to this email,
or by [filing an issue](https://github.com/dotcloud/docker/issues). We always appreciate it!
Production-ready
----------------
Docker is still alpha software, and not suited for production.
We are working hard to get there, and we are confident that it will be possible within a few months.
