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

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


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

$ docker run -dit --restart unless-stopped redis With docker inspect CONTAINER[1] you can verify RestartPolicy configuration.

To update restart policy execute:

docker update[2] --restart=always CONTAINER_ID|CONTAINER_NAME[3]
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.
 docker inspect -f "{{ .HostConfig.RestartPolicy }}"  CONTAINER_NAME

 docker update --restart=no $(docker container ls -aq)

 docker inspect -f "{{ .HostConfig.RestartPolicy}}" $(docker ps -a -q)
