# Docker Remote API v1.0
|
||
|
||
# 1. Brief introduction
|
||
|
||
- The Remote API is replacing rcli
|
||
- Default port in the docker daemon is 2375
|
||
- 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. Endpoints

# 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
|
||
|
||
## 3.2 Hijacking
|
||
|
||
In this first version of the API, some of the endpoints, like /attach,
|
||
/pull or /push uses hijacking to transport stdin, stdout and stderr on
|
||
the same socket. This might change in the future.
