# buildkitd.toml. Validated against the pinned image (v0.34.1-rootless): `buildctl debug workers
# -v` reports "Maximum used space: 4.29GB / Reserved space: 1.07GB" for the default policy.
#
# WHY 4GB. The cache lives in an emptyDir on the NODE's disk (deployment.yaml), and the nodes had
# 7-9 GB free when this was written. The largest image (toolbox) is ~1.4 GB uncompressed; the
# three images share their Fedora base. The emptyDir's sizeLimit sits above this cap, so GC
# trims the cache well before the kubelet would evict the pod for exceeding it.
