Container exiting with code 0 makes workflow fail

[mszulik]

Note: This is for v5, as I couldn't test it with v6 yet

We have a container which exits with status code 0 after running a command.
After this, the workflow shows as failed, but the server is running and everything is working fine.

 Container app-app-1  Healthy
 Container app-worker-transcoding-1  Healthy
 Container app-worker-client-notifications-1  Healthy
 Container app-worker-email-1  Healthy
container app-initialize-1 exited (0)
