Today, we also saw how our Support Engineers do this for our customers. But we may also use the Process Manager in some cases. The recommended method is to use Docker restart policy. So far, we saw two ways for a Docker to restart the container on reboot. Similarly, it is not advisable to use the Process Manager inside a container. Now, we will see how our Support Engineers use a Process Manager to restart Docker.įor this, we configure the Process Manager to start the container using the default manual commands.īut we do not recommend to use both the restart policy along with the Process Manager. We recommend this option only if any outside process depends on the docker container. First up, learn how to keep Docker containers running by utilizing these five Docker restart container tips. We can use this in the case of Docker also. Common Process Managers are systemd, supervisor, etc. In some cases, we use a Process Manager in Linux to automatically restart services that fail. Using Process manager to restart Docker on reboot Similarly, for the newly created container, we use the command, To wipe you existing container, use command - docker rm -f mycontainer. Wipe out the existing container and re-run docker run -namemycontainer image. For already created containers, our Support Engineers use docker update to start restart policy. Instead of running it using the command docker run -namemycontainer image, you may just start the existing container which you just trying and the above answer helps. Restart policy to restart Docker on rebootīy default, the restart policy in Docker is no. Alternatively, we can also use a Process Manager for the same purpose. And we always recommend using a restart policy. Our Experts often configure Docker containers to restart on reboot. If you dont want a container to start (even one with -restart always flag), you simply need to remove it, docker rm. For example, to get the number of restarts for container my. The number of (attempted) restarts for a container can be obtained via docker inspect. The default is that Docker will try forever to restart the container. On service docker restart containers that where stopped or started with -restart always flag will be started again automatically on restart. You can specify the maximum amount of times Docker will try to restart the container when using the on-failure policy. How we configure docker containers to restart on reboot? Images dont start automatically, containers do. Now let us see how to restart the container on reboot.
