How to delete build cache (buildkit experimental)

When using the experimental docker buildkit features: https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/experimental.md Specifically: RUN --mount=type=cache,target=/root/mycache .... How do I clean up (delete) this cache mount when I want to trigger a fresh build? I would assume there would be a command similar to “docker volume rm” but the cache mounts don’t appear in docker v

“docker builder prune --filter type=exec.cachemount”

exec.cachemount見ると、キャッシュの様子分かって便利だった
