| + | #redirect [[Start configuration behavior and restart policy]] |
| − | | |
| − | *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>

| − | 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>
