This video by Shubham Gour provides a detailed, practical guide to Docker restart policies, which are essential for ensuring container availability in production environments. The tutorial covers how to manage container behavior after service or system restarts through four specific policies:
no (Default): The container does not restart automatically after it exits or the Docker daemon restarts (1:08-10:29).
always: The container will always restart if it stops, regardless of how it was stopped, ensuring high uptime (10:37-17:15).
unless-stopped: A more controlled approach that restarts the container automatically unless it was manually stopped by the user before the Docker daemon/system rebooted (17:43-23:53).
on-failure: The container restarts only if it exits due to an error, with the option to set a specific number of maximum retries (23:56-32:48).
Key takeaways for management:
Verification: Use docker inspect combined with grep to verify the active policy on any running container (6:25-7:12).
Dynamic Updates: You can change a container's restart policy on-the-fly without needing to recreate it by using the docker update --restart command (33:50-35:05).
Cleanup: The video also introduces the --rm flag, which is not a restart policy but a useful utility to automatically delete containers once they exit, keeping your environment clean (36:57-40:32).
