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

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.
