This repo is to reproduce a possible buildkitd storage leak.
The ./repro.sh script simply requires a kubernetes cluster/config setup
./repro.sh
This script should create a kubernetes namespace buildkit-repro with a statefulset for buildkitd and a statefulset + service for a docker registry. Once buildkit and the registry are ready, it will use kubectl cp/exec to build the app in ./testapp repeatedly (pushing to the registry each time), with a small "code" change per build to bust the cache a bit. It should also print out the disk usage reported by buildctl du and df -h each at the begining and end of the run.
