ci: disable provenance attestations on image pushes — ACR rejects them - #425
Merged
Conversation
Every nightly product-image push to registry.cn-shanghai.aliyuncs.com has been failing with denied: unknown manifest class for application/vnd.oci.empty.v1+json (runs 31749181599, 31826694057 and earlier): Aliyun ACR rejects the OCI attestation manifests buildx attaches by default. Set provenance: false and sbom: false on both push steps (product image and ci-builder) so pushes emit plain image manifests both registries accept.

What this PR does / why we need it:
The nightly "Build and Push Images" runs have been failing on both architectures (e.g. runs 31749181599 from the 2026-08-13 cron — predating #418 — and yesterday's dispatch 31826694057) with:
on the ACR push. Aliyun ACR rejects the OCI attestation manifests that buildx now attaches by default. This sets
provenance: false/sbom: falseon both push steps — the product image build and the newci-builderjob (which pushes to the same ACR mirror and would fail identically on its first real publish).🤖 Generated with Claude Code
