This tool is created to periodically remove orphaned volumes where the contents are not going to need future retrieval. In some environments where containers are treated ephemerally and have high turnover there is the potential to generate a lot of space consuming orphaned volumes. It is VERY difficult to track down the origin of a particular volume once the container it was attached to is gone.
docker run -d --privileged -v /var/lib/docker:/var/lib/docker -v /var/run/docker.sock:/var/run/docker.sock cloudnautique/vol-cleanup [-n] -i 5
If you run with -n
it will log what it would delete.
To generate a statically linked (Linux) go binary
$ ./scripts/build
It will be placed in the ./dist
directory.
To generate a small Busybox container with the binary installed run:
$ IMAGE=<username>/vol-cleanup ./scripts/package
The default command of the image is to display the help page. Figured it was safer then starting to clean up files.
