Docker Buildx 0.31.0 includes full provenance attestations in the metadata output for multi-platform builds, resulting in 444KB+ JSON that exceeds bash argument list limits. Setting BUILDX_METADATA_PROVENANCE=disabled excludes provenance from the metadata file while keeping attestations attached to images in the registry.
