Add restart policy to running container


$ docker update [OPTIONS] CONTAINER [CONTAINER...]

Restart Policy

Policy Result
no Do not automatically restart the container when it exits. This is the default.
on-failure[:max-retries] Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts.
unless-stopped Restart the container unless it is explicitly stopped or Docker itself is stopped or restarted.
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.

Usage Docker Update

$ docker update restart=always <container>
$ docker inspect <container> 
 "RestartPolicy": {
    "Name": "always",
    "MaximumRetryCount": 0
