Documentation: minimal required disk space

[kkaempf]

Environment

• openSUSE Tumbleweed
• git checkout of cOS-Toolkit
• docker 20.10.6

Steps to reproduce

• freshly installed docker
• about 16GB free on /
• empty /var/lib/docker
• . .envrc
• cos-build

Expected behavior

Successful build of a sample (minimal?) cOS

Actual behavior

After some minutes, the disk is full and I see

> df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme0n1p4   50G   38G     0 100% /

> sudo du -sh /var/lib/docker/
100G	/var/lib/docker/

Open questions

• do we know how disk space is used ?
• can we generate a smaller image ?

[mudler]

There isn't much we can do here. During build multiple images are created depending on how many packages we have - the only action Item I see here is documenting the required space for building the cos-toolkit repository and ways to cleanup afterwards.

Locally to cleanup the cache I do something among the lines of:

$ docker images --filter='reference=quay.io/xx/xx' --format='{{.Repository}}:{{.Tag}}' | xargs -r docker rmi
$ docker image prune

or to cleanup all: docker system prune --force --volumes --all

Is this valid anymore @kkaempf ?

No.
