# Docker Remote API

 - The Remote API is replacing rcli
 - By default the Docker daemon listens on unix:///var/run/docker.sock
   and the client must have root access to interact with the daemon
 - If a group named *docker* exists on your system, docker will apply
   ownership of the socket to the group
 - 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
 - Since API version 1.2, the auth configuration is now handled client
   side, so the client has to send the authConfig as POST in /images/(name)/push
 - authConfig, set as the `X-Registry-Auth` header, is currently a Base64
   encoded (json) string with credentials:
   `{'username': string, 'password': string, 'email': string, 'serveraddress' : string}`



The current version of the API is v1.12

Calling /images/<name>/insert is the same as calling
/v1.12/images/<name>/insert

You can still call an old version of the api using
/v1.12/images/<name>/insert

## v1.12

### Full Documentation

[*Docker Remote API v1.12*](/reference/api/docker_remote_api_v1.12/)

### What's new

docker build now has support for the `forcerm` parameter to always remove containers

[*Docker Remote API v1.9*](/reference/api/docker_remote_api_v1.9/)

### What's new

`POST /build`

**New!**
This endpoint now takes a serialized ConfigFile which it
uses to resolve the proper registry auth credentials for pulling the
base image. Clients which previously implemented the version
accepting an AuthConfig object must be updated.

`GET /images/json`

The format of the json returned from this uri changed. Instead of an
entry for each repo/tag on an image, each image is only represented
once, with a nested attribute indicating the repo/tags that apply to
that image.

Instead of:

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

      {

docker v0.5.0
[51f6c4a](https://github.com/dotcloud/docker/commit/51f6c4a7372450d164c61e0054daf0223ddbd909)

### Full Documentation

[*Docker Remote API v1.3*](/reference/api/docker_remote_api_v1.3/)

### What's new

`GET /containers/(id)/top`

List the processes running inside a container.

`GET /events`

**New!**
Monitor docker's events via streaming or via polling

Builder (/build):

 - Simplify the upload of the build context
 - Simply stream a tarball instead of multipart upload with 4
   intermediary buffers
 - Simpler, less memory usage, less disk usage and faster

> **Warning**: 
> The /build improvements are not reverse-compatible. Pre 1.3 clients will
> break on /build.

List containers (/containers/json):

    Deleting an image is now improved, will only untag the image if it
