David Pelaez 8c2b170c6e Improved X-Registry-Auth content instructions
Hi,

this is a small contribution to fix some slightly unprecise information about the `X-Registry-Auth` header required to pull from private registries through the remote API. After a lot of trial and I error I managed to find that the documentation indications had this issues:

* Apparently single quotes cannot be used and double quotes (regular JSON) is required.
* Also the `auth` key must be passed even if empty or a 403 will result.
* It was not clear what the `serveraddress` had to be.

I added some small clarifications for anyone taking a look at the docs to keep them from the problems I've encountered. Hope this is helpful.

Thanks to all the contributors for bringing so much awesomeness to the linux world. :)

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 a POST in /images/(name)/push.
  • authConfig, set as the X-Registry-Auth header, is currently a Base64 encoded (JSON) string with the following structure: {"username": "string", "password": "string", "email": "string", "serveraddress" : "string", "auth": ""}. Notice that auth is to be left empty, serveraddress is a domain/ip without protocol, and that double quotes (instead of single ones) are required.

The current version of the API is v1.15

Calling /info is the same as calling /v1.15/info.

You can still call an old version of the API using /v1.14/info.

Docker Remote API v1.14

What's new

DELETE /containers/(id)

New! When using force, the container will be immediately killed with SIGKILL.

What's new

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
