If it fails then k8s will restart the container. If it is still running the you can safely reboot and check again that the application is restarting and see your docker is clean without unused of multiple containers. 131 1 Are you considering to run a CaaS like k8s as well If the container is run in k8s then one could define a liveness check. Wait until the killing process end in the previous shell, then close it and just leave ( don't do exit).Īnd check again in the remained terminal if the container is still running: $ docker ps But today, containers didnt start after the daily reboot. So far, I havent had any problems with that in the past 5 or 6 months running that particular setup. The physical server reboots every morning at 2am via cronjob executing reboot now. So when using this -restart unless-stopped policy, to ensure the restarting is working in case it stop by accident when you close the terminal, do once in another terminal as below: $ docker ps Im running several docker containers with restartalways on Ubuntu 18.04.1 LTS. Then, use the CONTAINER ID given in the output to select the container you wish to check the status of. This will generate a list of all running Docker containers.

Restart service containers Usage docker compose restart OPTIONS SERVICE. ![]() Implementing the setup described in the preceding section provides a more robust solution than relying on the hosts crontab.Adding the cron daemon to the containers that serve your application ensures anyone consuming your Docker image will have scheduled tasks setup automatically. Option docker run -rm will also problem with the -restart=always Separating Cron From Your Applications Services. Trying to automatically remove the container when it exist by put Docker recommends that you use restart policies, and avoid using process managers to start containers. Restart policies ensure that linked containers are started in the correct order. The problem is that if there are multiple containers with -restart=always when you run image of a newer version as discussed in docker - how do you disable auto-restart on a container?. Docker provides restart policies to control whether your containers start automatically when they exit, or when Docker restarts. Using -restart=always policy will handle restart of existing containers in case of reboot. ![]()
