|
+# Docker Remote API v1.21
|
|
|
+
|
|
|
+## 1. Brief introduction
|
|
|
+
|
|
|
+ - The Remote API has replaced `rcli`.
|
|
|
+ - The daemon listens on `unix:///var/run/docker.sock` but you can
|
|
|
+ [Bind Docker to another host/port or a Unix socket](
|
|
|
+ /articles/basics/#bind-docker-to-another-hostport-or-a-unix-socket).
|
|
|
+ - The API tends to be REST. However, for some complex commands, like `attach`
|
|
|
+ or `pull`, the HTTP connection is hijacked to transport `stdout`,
|
|
|
+ `stdin` and `stderr`.
|
|
|
+ - When the client API version is newer than the daemon's, these calls return an HTTP
|
|
|
+ `400 Bad Request` error message.

+ value is an object with a `Name` property of either `"always"` to
|
|
|
+ always restart or `"on-failure"` to restart only when the container
|
|
|
+ exit code is non-zero. If `on-failure` is used, `MaximumRetryCount`
|
|
|
+ controls the number of times to retry before giving up.
|
|
|
+ The default is not to restart. (optional)
|
|
|
+ An ever increasing delay (double the previous delay, starting at 100mS)
|
|

|
|
|
+ `json-file` logging driver.
|
|
|
+ - **CgroupParent** - Path to `cgroups` under which the container's `cgroup` is created. If the path is not absolute, the path is considered to be relative to the `cgroups` path of the init process. Cgroups are created if they do not already exist.

|
+ **Stream details**:
|
|
|
+
|
|
|
+ When using the TTY setting is enabled in
|
|
|
+ [`POST /containers/create`
|
|
|
+ ](/reference/api/docker_remote_api_v1.9/#create-a-container "POST /containers/create"),
|
|
|
+ the stream is the raw data from the process PTY and client's `stdin`.
|
|
|
+ When the TTY is disabled, then the stream is multiplexed to separate
|
|
|
+ `stdout` and `stderr`.
|
|
|
+
|
|
|
+ The format is a **Header** and a **Payload** (frame).
|
|
|
+
|
|
|
+ **HEADER**
|
|
|
+
|
|
|
+ The header contains the information which the stream writes (`stdout` or
|
|
|
+ `stderr`). It also contains the size of the associated frame encoded in the
|
|
|
+ last four bytes (`uint32`).
|
|
|
+
|
|
|
+ It is encoded on the first eight bytes like this:
|
|
|
+
|
|
|
+ header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}
|
|
|
+
|
|
|
+ `STREAM_TYPE` can be:
|
|
|
+
|
|
|
+- 0: `stdin` (is written on `stdout`)
|
|
|
+- 1: `stdout`
|
|
|
+- 2: `stderr`
|
|
|
+
|
|
|
+ `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of
|
|
|
+ the `uint32` size encoded as big endian.
|
|
|
+
|
|
|
+ **PAYLOAD**
|
|
|
+
|
|
|
+ The payload is the raw stream.
|
|
|
+
|
|
|
+ **IMPLEMENTATION**
|
|
|
+
|
|
|
+ The simplest way to implement the Attach protocol is the following:
|
|
|
+
|
|
|
+ 1. Read eight bytes.
|
|
|
+ 2. Choose `stdout` or `stderr` depending on the first byte.
|
|
|
+ 3. Extract the frame size from the last four bytes.
|
|
|
+ 4. Read the extracted size and output it on the correct output.
|
|
|
+ 5. Goto 1.

+Query Parameters:

+
|
|
|
+- **path** - resource in the container's filesystem to archive. Required.
|
|
|
+
|
|
|
+ If not an absolute path, it is relative to the container's root directory.
|
|
|
+ The resource specified by **path** must exist. To assert that the resource

|
|
+ is expected to be a directory, **path** should end in `/` or `/.`
|
|
|
+ (assuming a path separator of `/`). If **path** ends in `/.` then this
|
|
|
+ indicates that only the contents of the **path** directory should be

|
|
|
+The response shows a single image `Id` associated with two repositories
|
|
|
+(`RepoTags`): `localhost:5000/test/busybox`: and `playdate`. A caller can use
|
|
|
+either of the `RepoTags` values `localhost:5000/test/busybox:latest` or
|
|
|
+`playdate:latest` to reference the image.
|
|
|
+
|
|
|
+You can also use `RepoDigests` values to reference an image. In this response,
|
|
|
+the array has only one reference and that is to the
|
|
|
+`localhost:5000/test/busybox` repository; the `playdate` repository has no
|
|
|
+digest. You can reference this digest using the value:
|
|
|
+`localhost:5000/test/busybox@sha256:cbbf2f9a99b47fc460d...`
|
|
|
+
|
|
|
+See the `docker run` and `docker build` commands for examples of digest and tag
|

|
+
|
|
|
+- **all** – 1/True/true or 0/False/false, default false
|
|
|
+- **filters** – a JSON encoded value of the filters (a map[string][]string) to process on the images list. Available filters:
|
|
|
+ - `dangling=true`
|
|
|
+ - `label=key` or `label="key=value"` of an image label
|
|

+### Build image from a Dockerfile

+`POST /build`
|
|
|
+
|
|
|
+Build an image from a Dockerfile
|
|
|
+
|
|
|
+**Example request**:
|
|
|
+
|
|
|
+ POST /build HTTP/1.1
|
|
|
+
|
|
|
+ {{ TAR STREAM }}
|
|
|
+
|
|
|
+**Example response**:
|
|
|
+
|
|
|
+ HTTP/1.1 200 OK
|
|
|
+ Content-Type: application/json
|
|
|
+
|
|
|
+ {"stream": "Step 1..."}
|
|
|
+ {"stream": "..."}
|
|
|
+ {"error": "Error...", "errorDetail": {"code": 123, "message": "Error..."}}
|
|
|
+
|
|
|
+The input stream must be a `tar` archive compressed with one of the
|
|
|
+following algorithms: `identity` (no compression), `gzip`, `bzip2`, `xz`.
|
|
|
+
|
|
|
+The archive must include a build instructions file, typically called
|
|
|
+`Dockerfile` at the archive's root. The `dockerfile` parameter may be
|
|
|
+used to specify a different build instructions file. To do this, its value must be
|
|
|
+the path to the alternate build instructions file to use.
|
|
|
+
|
|
|
+The archive may include any number of other files,
|
|
|
+which are accessible in the build context (See the [*ADD build
|
|
|
+command*](/reference/builder/#dockerbuilder)).
|
|
|
+
|
|
|
+The build is canceled if the client drops the connection by quitting
|
|
|
+or being killed.
|
|
|
+
|
|
|
+Query Parameters:
|
|
|
+
|

+ ignored if `remote` is specified and points to an individual filename.
|
|
|
+- **t** – A repository name (and optionally a tag) to apply to
|
|
|
+ the resulting image in case of success.
|
|
|
+- **remote** – A Git repository URI or HTTP/HTTPS URI build source. If the
|
|
|
+ URI specifies a filename, the file's contents are placed into a file
|
|
|
+ called `Dockerfile`.
|
|
|
+- **q** – Suppress verbose build output.
|
|
|
+- **nocache** – Do not use the cache when building the image.
|
|
|
+- **pull** - Attempt to pull the image even if an older image exists locally.
|
|
|
+- **rm** - Remove intermediate containers after a successful build (default behavior).
|
|
|
+- **forcerm** - Always remove intermediate containers (includes `rm`).
|
|
|
+- **memory** - Set memory limit for build.
|
|
|
+- **memswap** - Total memory (memory + swap), `-1` to disable swap.
|
|
|

+### Image tarball format
|
|
|
+
|
|
|
+An image tarball contains one directory per image layer (named using its long ID),
|
|
|
+each containing these files:
|
|
|
+
|
|
|
+- `VERSION`: currently `1.0` - the file format version
|
|
|
+- `json`: detailed layer information, similar to `docker inspect layer_id`
|
|
|
+- `layer.tar`: A tarfile containing the filesystem changes in this layer
|
|
|
+
|
|
|
+The `layer.tar` file contains `aufs` style `.wh..wh.aufs` files and directories
|
|
|
+for storing attribute changes and deletions.
|
|
|
+
|
|
|
+If the tarball defines a repository, the tarball should also include a `repositories` file at
|
|
|
+the root that contains a list of repository and tag names mapped to layer IDs.
|
|
|
+
|
|
|
+```

+# 3. Going further
|
|
|
+
|
|
|
+## 3.1 Inside `docker run`
|
|
|
+
|
|
|
+As an example, the `docker run` command line makes the following API calls:
|
|
|
+
|
|
|
+- Create the container
|
|
|
+
|
|
|
+- If the status code is 404, it means the image doesn't exist:
|
|
|
+ - Try to pull it.
|
|
|
+ - Then, retry to create the container.
|
|
|
+
|
|
|
+- Start the container.
|
|
|
+
|
|
|
+- If you are not in detached mode:
|
|
|
+- Attach to the container, using `logs=1` (to have `stdout` and
|
|
|
+ `stderr` from the container's start) and `stream=1`
|
|
|
+
|
|
|
+- If in detached mode or only `stdin` is attached, display the container's id.
|
|
|
+
|
|
|
+## 3.2 Hijacking
|
|
|
+
|
|
|
+In this version of the API, `/attach`, uses hijacking to transport `stdin`,
|
|
|
+`stdout`, and `stderr` on the same socket.
|
|
|
+
|
|
|
+To hint potential proxies about connection hijacking, Docker client sends
|
|
|
+connection upgrade headers similarly to websocket.
|
|
|
+
|
|
|
+ Upgrade: tcp
|
|
|
+ Connection: Upgrade
|
|
|
+
|
|
|
+When Docker daemon detects the `Upgrade` header, it switches its status code
|
|
|
+from **200 OK** to **101 UPGRADED** and resends the same headers.
|
|
|
+
|
|
|
+
|
|
|
+## 3.3 CORS Requests
|
|
|
+
|
|
|
+To set cross origin requests to the remote api please give values to
|
|
|
+`--api-cors-header` when running Docker in daemon mode. Set * (asterisk) allows all,
|
|
|
+default or blank means CORS disabled
|
|
|
+
|
|
|
+ $ docker daemon -H="192.168.1.9:2375" --api-cors-header="http://foo.bar"
