Note

Buildx v0.10 enables support for a minimal SLSA Provenance attestation, which requires support for OCI-compliant multi-platform images. This may introduce issues with registry and runtime support (e.g. Google Cloud Run and AWS Lambda). You can optionally disable the default provenance attestation functionality using provenance: false.

• Revert disable provenance by default if not set by @​crazy-max in https://github.com/docker/build-push-action/pull/784
