quipper/cleanup-deis-images repository overview

⁠Delete old Releases of Docker Images

If you release often your build server will collect a large amount of images that are no longer used. This script keeps your Deis cluster slick by removing app versions that are older than n releases.

⁠Usage

You need to mount the docker socket into the container in order for the script to access and cleanup the images.

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock quipper/cleanup-deis-images

⁠Configure

You can specify how many versions should be kept (4 per default) by setting the KEEP_LAST_VERSIONS env var.

docker run --rm \
 -v /var/run/docker.sock:/var/run/docker.sock \
 -e KEEP_LAST_VERSIONS=3 quipper/cleanup-deis-images

If you have images from v2 up to v6 the script will remove all images older than v6 - n. With the default of 4 this will only remove the image 10.21.2.170:5000/zermatt-microsite:v2

10.21.2.170:5000/zermatt-microsite:v6
10.21.2.170:5000/zermatt-microsite:v5
10.21.2.170:5000/zermatt-microsite:v4
10.21.2.170:5000/zermatt-microsite:v3
10.21.2.170:5000/zermatt-microsite:v2
