Quick Update Docker Containers

I run a home docker server, for the most part it was a “set it and forget” sort of setup. Occasionally I update the docker images and always have to remind myself of the steps involved as I don’t do it often enough. I built my initial docker setup following most of this guide.

Here are the steps I take to update my docker images and Ubuntu server.

1. Sudo apt-get update
   1. Always a good idea to install server updates first.
2. Docker-compose -f ~/docker/docker-compose.yml down
   1. You need to run this command from the folder where your docker compose file is located. This will force a shutdown of all of your docker containers included in your compose file.
3. Docker-compose pull
   1. This command will pull down the new docker container images from your compose repository.
4. Docker-compose -f ~/docker/docker-compose.yml up
   1. This command forces all of your docker container images to start up again.
5. Check on the status of your docker containers by running docker ps -a.
6. Restart your server, if necessary, with the shutdown -r command.
