contentutil: add pull through cache for attestations chain resolve by tonistiigi · Pull Request #6435 · moby/buildkit (original) (raw)

Currently attestation chains were always loaded directly from registry on each pull.

This adds cache capability to resolver so all the pulled manifests are first pulled to content store and kept there with GC labels references from the root manifest.

If blob or referrers request already exists in the content store then local response is used without registry requests.
