How to cleanup (unused) resources

---

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

If you use a Docker version newer than > 1.13 you can use Dockers builtin cleanup tool purge.

The new way (Docker > 1.13)

Network

To purge the networks (Docker Docs)

docker network prune

Containers, Volumes, Images

And to purge the docker system (Docker Docs)

docker system prune

{{< alert theme="info">}} For some users the docker system prune command dosen't delete the build cache so if thats the case that a look at the Build system leftovers section
{{< /alert>}}

The old way (Docker < 1.13)

Delete Volumes

{{< alert theme="info" >}} For more info and a complete shell script see: https://github.com/chadoe/docker-cleanup-volumes {{< /alert >}}

docker volume rm $(docker volume ls -qf dangling=true)

or

docker volume ls -qf dangling=true | xargs -r docker volume rm

Delete Networks

docker network ls

docker network ls | grep "bridge"

docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

or

docker network ls | awk '$3 == "bridge" && $2 != "bridge" { print $1 }'

Build system leftovers

If your system is also used for building images you might have a look at cleaning up garbage created by the builders using:

docker buildx prune --all

and

docker builder prune --all
