dcgc
Remove old docker containers and docker images.
dcgc will remove stopped containers and unused images that are older than “max age”. Running containers, and images which are used by a container are never removed.
Maximum age can be specificied with any format supported by pytimeparse.
Example:
dcgc --max-container-age 3days --max-image-age 30days
Prevent images from being removed
dcgc supports an image exclude list. If you have images that you’d like to keep around forever you can use the exclude list to prevent them from being removed.
--exclude-image Never remove images with this tag. May be specified more than once. --exclude-image-file Path to a file which contains a list of images to exclude, one image tag per line.
dcstop
Stop containers that have been running for too long.
dcstop will docker stop containers where the container name starts with –prefix and it has been running for longer than –max-run-time.
Example:
dcstop --max-run-time 2days --prefix "projectprefix_"
