Restart policies (–restart)

Use Docker’s --restart to specify a container’s restart policy. A restart policy controls whether the Docker daemon restarts a container after exit. Docker supports the following restart policies:

Policy	Result
no	Do not automatically restart the container when it exits. This is the default.
failure	Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts.
always	Always restart the container regardless of the exit status. When you specify always, the Docker daemon will try to restart the container indefinitely. The container will also always start on daemon startup, regardless of the current state of the container.
