# Docker Remote API v1.11
|
|
|
|
|
|
|
|
|
|
## 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*](../../../use/basics/#bind-docker).
|
|
|
|
|
- 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`
|
|
|
|
|
|
|
|
|
|

**Stream details**:
|
|
|
|
|
|
|
|
|
|
When using the TTY setting is enabled in
|
|
|
|
|
[`POST /containers/create`
|
|
|
|
|
](../docker_remote_api_v1.9/#post--containers-create "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 writen 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 byets
|
|
|
|
|
4. Read the extracted size and output it on the correct output
|
|
|
|
|
5. Goto 1)
|
|
|
|
|
|
|
|
|

## 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 exists:
|
|
|
|
|
: - 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="192.168.1.9:4243" --api-enable-cors
|
