Docker Auto-Update

This is a tool that helps you keeping your Docker images and containers up-to-date. It basically consists of three files:

You'll find more information on the Docker Auto-Update tool in my blog.


To install the Docker Auto-Update tool, you may clone the repository at GitHub. Then,

  1. move the ./etc/cron.daily/docker-updater script to /etc/cron.daily/docker-updater
  2. move the ./etc/default/docker-updater config file to /etc/default/docker-updater
  3. update the setup in /etc/default/docker-updater -- at least set ENABLED=1
  4. create a list of Docker Compose config files in /etc/docker-compose-auto-update.conf - one path to a docker-compose.yml per line.

If you're running a Debian-based system, you may instead use my apt-repository to install the Docker-Tools. In that case you just need to run

aptitude install bf-docker-tools

Afterwards, configure /etc/default/docker-updater and at least set ENABLED=1. This way, you'll always stay up-to-date with bug fixes and new features :)
