# 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](../../quickstart.md#bind-docker-to-another-host-port-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.

    -   **Binds** – A list of volume bindings for this container. Each volume binding is a string in one of these forms:
           + `container_path` to create a new volume for the container
           + `host_path:container_path` to bind-mount a host path into the container
           + `host_path:container_path:ro` to make the bind-mount read-only inside the container.
           + `volume_name:container_path` to bind-mount a volume managed by a volume plugin into the container.
           + `volume_name:container_path:ro` to make the bind mount read-only inside the container.

    -   **GroupAdd** - A list of additional groups that the container process will run as
    -   **RestartPolicy** – The behavior to apply when the container exits.  The
            value is an object with a `Name` property of either `"always"` to
            always restart, `"unless-stopped"` to restart always except when
            user has manually stopped the container 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)
            is added before each restart to prevent flooding the server.
    -   **NetworkMode** - Sets the networking mode for the container. Supported
          standard values are: `bridge`, `host`, `none`, and `container:<name|id>`. Any other value is taken
          as a custom network's name to which this container should connect to.
    -   **Devices** - A list of devices to add to the container specified as a JSON object in the
      form
          `{ "PathOnHost": "/dev/deviceName", "PathInContainer": "/dev/deviceName", "CgroupPermissions": "mrw"}`
    -   **Ulimits** - A list of ulimits to set in the container, specified as
          `{ "Name": <name>, "Soft": <soft limit>, "Hard": <hard limit> }`, for example:
          `Ulimits: { "Name": "nofile", "Soft": 1024, "Hard": 2048 }`
    -   **SecurityOpt**: A list of string values to customize labels for MLS
        systems, such as SELinux.
    -   **LogConfig** - Log configuration for the container, specified as a JSON object in the form
          `{ "Type": "<driver_name>", "Config": {"key1": "val1"}}`.
          Available types: `json-file`, `syslog`, `journald`, `gelf`, `awslogs`, `none`.
          `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.
    -   **VolumeDriver** - Driver that this container users to mount volumes.

Query Parameters:

-   **name** – Assign the specified name to the container. Must
    match `/?[a-zA-Z0-9_-]+`.

Status Codes:

-   **201** – no error
-   **404** – no such container

-   **101** – no error, hints proxy about hijacking
-   **200** – no error, no upgrade header found
-   **400** – bad parameter
-   **404** – no such container
-   **500** – server error

    **Stream details**:

    When using the TTY setting is enabled in
    [`POST /containers/create`
    ](#create-a-container),
    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.

**Example request**:

    POST /containers/4fa6e0f0c678/copy HTTP/1.1
    Content-Type: application/json

    {
         "Resource": "test.txt"
    }

**Example response**:

    HTTP/1.1 200 OK
    Content-Type: application/x-tar

    {{ TAR STREAM }}

Status Codes:

-   **200** – no error
-   **404** – no such container
-   **500** – server error

### Retrieving information about files and folders in a container

`HEAD /containers/(id or name)/archive`

See the description of the `X-Docker-Container-Path-Stat` header in the
following section.

### Get an archive of a filesystem resource in a container

`GET /containers/(id or name)/archive`

Get an tar archive of a resource in the filesystem of container `id`.

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
    copied. A symlink is always resolved to its target.

    **Note**: It is not possible to copy certain system files such as resources
    under `/proc`, `/sys`, `/dev`, and mounts created by the user in the
    container.

**Example request**:

        GET /containers/8cce319429b2/archive?path=/root HTTP/1.1

**Example response**:

        HTTP/1.1 200 OK
        Content-Type: application/x-tar
        X-Docker-Container-Path-Stat: eyJuYW1lIjoicm9vdCIsInNpemUiOjQwOTYsIm1vZGUiOjIxNDc0ODQwOTYsIm10aW1lIjoiMjAxNC0wMi0yN1QyMDo1MToyM1oiLCJsaW5rVGFyZ2V0IjoiIn0=

        {{ TAR STREAM }}

On success, a response header `X-Docker-Container-Path-Stat` will be set to a
base64-encoded JSON object containing some filesystem header information about
the archived resource. The above example value would decode to the following
JSON object (whitespace added for readability):

        {
            "name": "root",
            "size": 4096,
            "mode": 2147484096,
            "mtime": "2014-02-27T20:51:23Z",
            "linkTarget": ""
        }

A `HEAD` request can also be made to this endpoint if only this information is
desired.

Status Codes:

- **200** - success, returns archive of copied resource
- **400** - client error, bad parameter, details in JSON response body, one of:
    - must specify path parameter (**path** cannot be empty)
    - not a directory (**path** was asserted to be a directory but exists as a
      file)
- **404** - client error, resource not found, one of:
    – no such container (container `id` does not exist)
    - no such file or directory (**path** does not exist)
- **500** - server error

### Extract an archive of files or folders to a directory in a container

`PUT /containers/(id or name)/archive`

Upload a tar archive to be extracted to a path in the filesystem of container
`id`.

Query Parameters:

- **path** - path to a directory in the container
    to extract the archive's contents into. Required.

    If not an absolute path, it is relative to the container's root directory.
    The **path** resource must exist.
- **noOverwriteDirNonDir** - If "1", "true", or "True" then it will be an error
    if unpacking the given content would cause an existing directory to be
    replaced with a non-directory and vice versa.

**Example request**:

    PUT /containers/8cce319429b2/archive?path=/vol1 HTTP/1.1
    Content-Type: application/x-tar

    {{ TAR STREAM }}

**Example response**:

    HTTP/1.1 200 OK

Status Codes:

- **200** – the content was extracted successfully
- **400** - client error, bad parameter, details in JSON response body, one of:
    - must specify path parameter (**path** cannot be empty)
    - not a directory (**path** should be a directory but exists as a file)
    - unable to overwrite existing directory with non-directory
      (if **noOverwriteDirNonDir**)
    - unable to overwrite existing non-directory with directory
      (if **noOverwriteDirNonDir**)
- **403** - client error, permission denied, the volume
    or container rootfs is marked as read-only.
- **404** - client error, resource not found, one of:
    – no such container (container `id` does not exist)
    - no such file or directory (**path** resource does not exist)
- **500** – server error

**Example response, with digest information**:

    HTTP/1.1 200 OK
    Content-Type: application/json

    [
      {
        "Created": 1420064636,

        "Size": 0,
        "VirtualSize": 2429728,
        "Labels": {}
      }
    ]

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
references on the command line.

Query Parameters:

-   **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
-   **filter** - only return images with the specified name

### 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.md#dockerbuilder)).

The build is canceled if the client drops the connection by quitting
or being killed.

Query Parameters:

-   **dockerfile** - Path within the build context to the Dockerfile. This is
        ignored if `remote` is specified and points to an individual filename.
-   **t** – A name and optional tag to apply to the image in the `name:tag` format.
        If you omit the `tag` the default `latest` value is assumed.
        You can provide one or more `t` parameters.
-   **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 enable unlimited swap.
-   **cpushares** - CPU shares (relative weight).
-   **cpusetcpus** - CPUs in which to allow execution (e.g., `0-3`, `0,1`).
-   **cpuperiod** - The length of a CPU period in microseconds.
-   **cpuquota** - Microseconds of CPU time that the container can get in a CPU period.
-   **buildargs** – JSON map of string pairs for build-time variables. Users pass
        these values at build-time. Docker uses the `buildargs` as the environment
        context for command(s) run via the Dockerfile's `RUN` instruction or for
        variable expansion in other Dockerfile instructions. This is not meant for
        passing secret values. [Read more about the buildargs instruction](../../reference/builder.md#arg)

    Request Headers:

-   **Content-type** – Set to `"application/tar"`.
-   **X-Registry-Config** – A base64-url-safe-encoded Registry Auth Config JSON
        object with the following structure:

            {
                "docker.example.com": {
                    "username": "janedoe",
                    "password": "hunter2"
                },
                "https://index.docker.io/v1/": {
                    "username": "mobydock",
                    "password": "conta1n3rize14"
                }
            }

        This object maps the hostname of a registry to an object containing the
        "username" and "password" for that registry. Multiple registries may
        be specified as the build may be based on an image requiring
        authentication to pull from any arbitrary registry. Only the registry
        domain name (and port if not the default "443") are required. However
        (for legacy reasons) the "official" Docker, Inc. hosted registry must
        be specified with both a "https://" prefix and a "/v1/" suffix even
        though Docker will prefer to use the v2 registry API.

Status Codes:

-   **200** – no error
-   **500** – server error

### Create an image

`POST /images/create`

Create an image either by pulling it from the registry or by importing it

**Example request**:

    POST /images/create?fromImage=ubuntu HTTP/1.1

**Example response**:

    HTTP/1.1 200 OK
    Content-Type: application/json

    {"status": "Pulling..."}
    {"status": "Pulling", "progress": "1 B/ 100 B", "progressDetail": {"current": 1, "total": 100}}
    {"error": "Invalid..."}
    ...

When using this endpoint to pull an image from the registry, the
`X-Registry-Auth` header can be used to include
a base64-encoded AuthConfig object.

Query Parameters:

-   **fromImage** – Name of the image to pull. The name may include a tag or
        digest. This parameter may only be used when pulling an image.
-   **fromSrc** – Source to import.  The value may be a URL from which the image
        can be retrieved or `-` to read the image from the request body.
        This parameter may only be used when importing an image.
-   **repo** – Repository name given to an image when it is imported.
        The repo may include a tag. This parameter may only be used when importing
        an image.
-   **tag** – Tag or digest.

    Request Headers:

-   **X-Registry-Auth** – base64-encoded AuthConfig object

Status Codes:

-   **200** – no error
-   **500** – server error

### Push an image on the registry

`POST /images/(name)/push`

Push the image `name` on the registry

**Example request**:

    POST /images/test/push HTTP/1.1

**Example response**:

    HTTP/1.1 200 OK
    Content-Type: application/json

    {"status": "Pushing..."}
    {"status": "Pushing", "progress": "1/? (n/a)", "progressDetail": {"current": 1}}}
    {"error": "Invalid..."}
    ...

If you wish to push an image on to a private registry, that image must already have a tag
into a repository which references that registry `hostname` and `port`.  This repository name should

### Get a tarball containing all images in a repository

`GET /images/(name)/get`

Get a tarball containing all images and metadata for the repository specified
by `name`.

If `name` is a specific name and tag (e.g. ubuntu:latest), then only that image
(and its parents) are returned. If `name` is an image ID, similarly only that
image (and its parents) are returned, but with the exclusion of the
'repositories' file in the tarball, as there were no image names referenced.

See the [image tarball format](#image-tarball-format) for more details.

**Example request**

    GET /images/ubuntu/get

**Example response**:

    HTTP/1.1 200 OK
    Content-Type: application/x-tar

    Binary data stream

Status Codes:

-   **200** – no error
-   **500** – server error

### Get a tarball containing all images.

`GET /images/get`

Get a tarball containing all images and metadata for one or more repositories.

For each value of the `names` parameter: if it is a specific name and tag (e.g.
`ubuntu:latest`), then only that image (and its parents) are returned; if it is
an image ID, similarly only that image (and its parents) are returned and there
would be no names referenced in the 'repositories' file for this image ID.

See the [image tarball format](#image-tarball-format) for more details.

**Example request**

    GET /images/get?names=myname%2Fmyapp%3Alatest&names=busybox

**Example response**:

    HTTP/1.1 200 OK
    Content-Type: application/x-tar

    Binary data stream

-   **200** – no error
-   **500** – server error

### Load a tarball with a set of images and tags into docker

`POST /images/load`

Load a set of images and tags into a Docker repository.

**Example request**

    POST /images/load

    Tarball in body

**Example response**:

    HTTP/1.1 200 OK

Status Codes:

-   **200** – no error
-   **500** – server error

### 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.

```
{"hello-world":
    {"latest": "565a9d68a73f6706862bfe8409a7f659776d4d60a8d096eb4a3cbce6999cc2a1"}
}
```

# 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"
