# Docker Remote API v1.6

# 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.
 - The API tends to be REST, but for some complex commands, like `attach`
   or `pull`, the HTTP connection is hijacked to transport `stdout, stdin`
   and `stderr`

## 2.1 Containers

### List containers

`GET /containers/json`

List containers

**Example request**:

        GET /containers/json?all=1&before=8dfafdbc3a40&size=1 HTTP/1.1

**Example response**:

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

    **More Complex Example request, in 2 steps.** **First, use create to
    expose a Private Port, which can be bound back to a Public Port a
    startup**:

        POST /containers/create HTTP/1.1
        Content-Type: application/json

        {
             "Cmd":[
                     "/usr/sbin/sshd","-D"
             ],
             "Image":"image-with-sshd",
             "ExposedPorts":{"22/tcp":{}}
             }

**Example response**:

        HTTP/1.1 201 OK
        Content-Type: application/json

        {
             "Id":"e90e34656806"
             "Warnings":[]
        }

    **Second, start (using the ID returned above) the image we jus
    created, mapping the ssh port 22 to something on the host**:

        POST /containers/e90e34656806/start HTTP/1.1
        Content-Type: application/json

        {
             "PortBindings": { "22/tcp": [{ "HostPort": "11022" }]}
             }

**Example response**:

        HTTP/1.1 204 No Conten
        Content-Type: text/plain; charset=utf-8
        Content-Length: 0

    **Now you can ssh into your new container on port 11022.**

    **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 will contain the information on which stream write the
    stream (stdout or stderr). It also contain the size of the
    associated frame encoded on the last 4 bytes (uint32).

    It is encoded on the first 8 bytes like this:

        header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}

    `STREAM_TYPE` can be:

-   0: stdin (will be written on stdout)
-   1: stdout
-   2: stderr

    `SIZE1, SIZE2, SIZE3, SIZE4` are the 4 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 8 bytes
    2.  chose stdout or stderr depending on the first byte
    3.  Extract the frame size from the last 4 bytes
    4.  Read the extracted size and output it on the correct output
    5.  Goto 1)

### Attach to a container (websocket)

`GET /containers/(id)/attach/ws`

Attach to the container `id` via websocket

Implements websocket protocol handshake according to [RFC 6455](http://tools.ietf.org/html/rfc6455)

**Example request**

        GET /containers/e90e34656806/attach/ws?logs=0&stream=1&stdin=1&stdout=1&stderr=1 HTTP/1.1

**Example response**

        {{ STREAM }}

Query Parameters:

-   **logs** – 1/True/true or 0/False/false, return logs. Default false

# 3. Going further

## 3.1 Inside `docker run`

Here are the steps of `docker run` :

-   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. This might change in the future.

## 3.3 CORS Requests

To enable cross origin requests to the remote api add the flag
"--api-enable-cors" when running docker in daemon mode.

    $ docker -d -H="192.168.1.9:2375" --api-enable-cors
