Editing Docker Start configuration behavior and restart policy

To configure the '''start configuration behavior or the restart policy''' for a container (both of them), use the <code>--restart</code> flag when using the <code>docker run</code> command. The value of the <code>--restart</code> flag can be any of the following:

*Do not automatically restart the container. (the default): <code>no</code>
*Restart the container if it exits due to an error, which manifests as a non-zero exit code: <code>on-failure</code>
*Restart the container unless it is explicitly stopped or Docker itself is stopped or restarted: <code>unless-stopped</code>	
*Always restart the container if it stops: <code>always</code>


The following example starts a Redis container and configures it to always restart unless it is explicitly stopped or Docker is restarted:

<code>$ docker run -dit --restart '''unless-stopped''' redis</code>
With <code>[[/docker inspect/]] CONTAINER</code><ref>https://stackoverflow.com/questions/43108227/is-it-possible-to-show-the-restart-policy-of-a-running-docker-container</ref> you can verify <code>RestartPolicy</code> configuration.

To update restart policy execute:
:<code>[[docker update]]</code><ref>https://docs.docker.com/engine/reference/commandline/update/</ref> --restart=always CONTAINER_ID|CONTAINER_NAME<ref>docker update --restart=always 90bf248337dc</ref>
:If the container is started  with “--rm” flag, you cannot update the restart policy for it. The AutoRemove and RestartPolicy are mutually exclusive for the container.
