# Docker Remote API v1.12
|
||
|
||
## 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, 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`
|
||
](/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).
|
||
|

|
||
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
|
||
|
||

### Monitor Docker's events
|
||
|
||
`GET /events`
|
||
|
||
Get container events from docker, either in real time via streaming, or via
|

polling (using since).

|
||
Docker containers will report the following events:
|
||
|
||
create, destroy, die, export, kill, pause, restart, start, stop, unpause
|
||
|
||
and Docker images will report:
|
||
|
||
untag, delete
|
||
|
||
**Example request**:
|
||
|
||
GET /events?since=1374067924
|
||
|
||
**Example response**:
|
||
|
||
HTTP/1.1 200 OK
|
||
Content-Type: application/json
|
||
|
||
{"status": "create", "id": "dfdf82bd3881","from": "ubuntu:latest", "time":1374067924}
|
||
{"status": "start", "id": "dfdf82bd3881","from": "ubuntu:latest", "time":1374067924}

|
||
|

|
||
|
||
- **since** – timestamp used for polling
|
||
- **until** – timestamp used for polling
|
||
|
||
Status Codes:
|
||
|
||

### Image tarball format
|
||
|
||
An image tarball contains one directory per image layer (named using its long ID),
|
||
each containing three files:
|
||
|
||
1. `VERSION`: currently `1.0` - the file format version
|
||
2. `json`: detailed layer information, similar to `docker inspect layer_id`
|
||
3. `layer.tar`: A tarfile containing the filesystem changes in this layer
|
||
|
||
The `layer.tar` file will contain `aufs` style `.wh..wh.aufs` files and directories
|
||
for storing attribute changes and deletions.
|
||
|
||
If the tarball defines a repository, there will also be 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. 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
