tutum/cleanup

System container used by Tutum to remove unused images and volumes. System containers are launched, configured and managed automatically by Tutum.

Usage

Docker < 1.9

docker run -d \
  --privileged \
  -v /var/run/docker.sock:/var/run/docker.sock:rw \
  -v /var/lib/docker:/var/lib/docker:rw \
  [-e IMAGE_CLEAN_INTERVAL=1] \
  [-e IMAGE_CLEAN_DELAYED=1800] \
  [-e VOLUME_CLEAN_INTERVAL=1800] \
  [-e IMAGE_LOCKED="ubuntu:trusty, tutum/curl:trusty"] \
  tutum/cleanup

Docker >= 1.9

docker run -d \
  -v /var/run/docker.sock:/var/run/docker.sock:rw \
  [-e IMAGE_CLEAN_INTERVAL=1] \
  [-e IMAGE_CLEAN_DELAYED=1800] \
  [-e IMAGE_LOCKED="ubuntu:trusty, tutum/curl:trusty"] \
  tutum/cleanup

Environment variables

Key	Description
IMAGE_CLEAN_INTERVAL	(optional) How long to wait between cleanup runs (in seconds), 1 by default.
IMAGE_CLEAN_DELAYED	(optional) How long to wait to consider an image unused (in seconds), 1800 by default.
VOLUME_CLEAN_INTERVAL	(optional) How long to wait to consider a volume unused (in seconds), 1800 by default.
IMAGE_LOCKED	(optional) A list of images that will not be cleaned by this container, separated by ,

Notice:

From docker 1.9 onwards, volumes are a top level entity and can be removed using docker volume rm <name>. This image will not cleanup volumes when connected to a docker engine 1.9+ to avoid potential data loss.
