Restart Policy

The container's restart policy specifies how container are restarted when the docker server is restarted. It is maintained in /var/lib/docker/containers/<container-id>/hostconfig.json as:

{ ... "RestartPolicy":{"Name":"no","MaximumRetryCount":0}, ... }

Note that the json file must not be edited directly. If the restart policy has to be changed, that must be done with docker update.

The policy for a specific container can be retrieved with docker inspect.
