fix(template): use linux/arm64/v8 for Go distroless base image#900
Merged
Conversation
The gcr.io/distroless/base image index labels its arm64 manifest with variant "v8". rules_oci builds its platform-match string from os/arch/variant, so the manifest's platform is "linux/arm64/v8". The Go oci.pull requested bare "linux/arm64", which never matches and fails on Apple Silicon with: No matching manifest found in image gcr.io/distroless/base for platform linux/arm64 CI passed because it runs on linux/amd64, which matched fine — only the arm64 fetch path (exercised on Apple Silicon) was broken. The Python base image in the same file already used the variant-qualified form; this brings the Go entry in line. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
