Type Alias: ContainerRestartPolicy

ContainerRestartPolicy = "" | "no" | "always" | "unless-stopped" | "on-failure" | `on-failure:${number}`

When Docker restarts a container after it exits:

• '': never (no policy, the same as 'no');
• 'no': never;
• 'always': always, and when the Docker daemon starts, even if the container was stopped by hand;
• 'unless-stopped': always, except after the container was stopped by hand;
• 'on-failure': only when it exits with a non-zero code, with no limit on the retries;
• 'on-failure:N' ('on-failure:3'): only when it exits with a non-zero code, N times at most (as docker run --restart on-failure:3).
