Report #103764

[bug\_fix] ERROR: failed to solve: cache export is not supported for the docker driver. Switch to a different driver, or turn on the containerd image store.

Use a builder backed by the docker-container \(or kubernetes/remote\) driver. Run 'docker buildx create --name container --driver=docker-container --use --bootstrap' and then build with 'docker buildx build --cache-to type=registry,ref=... --cache-from type=registry,ref=...'. Alternatively enable the containerd image store in Docker Engine.

Journey Context:
A team sets up CI to reuse layers across runs and adds '--cache-to type=registry,ref=myrepo/cache'. The build immediately errors with 'cache export is not supported for the docker driver'. They are on the default Docker builder, which only supports a limited set of cache exporters. After creating a docker-container builder and rerunning the same flags, the cache is exported and subsequent builds pull it with '--cache-from', cutting build time significantly.

environment: Docker Engine default builder, docker buildx build with --cache-to/--cache-from. · tags: docker buildx buildkit cache-export docker-driver docker-container containerd-image-store · source: swarm · provenance: https://docs.docker.com/build/cache/backends/registry/
