Summary
Reason for change
The unqualified
gcr.io/distroless/static:nonrootalias can move to a newer Debian major release without a repository change. The explicit Debian 13 tag preserves the intended operating-system version, while the OCI index digest makes the selected base immutable across supported architectures.Fixes #12922
How to test
linux/amd64,linux/arm64, andlinux/arm/v7using the pinned index.ucpd --helpsuccessfully on all three architectures under native execution or QEMU.User=65532:65532,WorkingDir=/,Entrypoint=["/ucpd"], Debian 13 identity, a nonempty CA certificate bundle, and the expected built-in provider manifests.git diff --checksuccessfully.File change summary
