:title: Remote API v1.1
:description: API Documentation for Docker
:keywords: API, Docker, rcli, REST, documentation

======================
Docker Remote API v1.1
======================

.. contents:: Table of Contents

1. Brief introduction
=====================

- The Remote API is replacing rcli
- Default port in the docker daemon is 4243
- 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'
-----------------------

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.
