Articles, scripts related to docker and cleaning up images, containers etc

ideas and notes

  • gather a bunch of useful clean up commands from below and put into a daily cron job, which should be provisioned to all servers kkthx
  • pipe to xargs using -r, e.g. $(docker ps -a -q -f status=exited) | xargs -r docker rm -v to avoid getting docker rm errors if empty input
  • be careful about removing exited containers together with data containers, e.g. docker rm -v $(docker ps -a -q -f status=exited)
  • think about creating commands that only remove containers that exited some time ago, e.g. docker ps -a | grep Exited | grep "days ago" | awk '{print $1}' | xargs docker rm

Cleanup and reset docker on Jenkins workers / slaves
#!/bin/bash
# This script should be located on each Jenkins slave, and the jenkins user should have permission to run it with sudo
# Attempts to cleanly stop and remove all containers, volumes and images.
docker ps -q | xargs --no-run-if-empty docker stop
docker ps -q -a | xargs --no-run-if-empty docker rm --force --volumes
docker volume ls -q | xargs --no-run-if-empty docker volume rm
docker images -a -q | xargs --no-run-if-empty docker rmi -f
# Stops the docker service, unmounts all docker-related mounts, removes the entire docker directory, and starts docker again.
