# Anchor a backend per-arch digest in quay.io/go-skynet/ci-cache so quay's
|
||
# garbage collector won't reap the manifest before backend_merge.yml runs.
|
||
#
|
||
# Context: backend_build.yml pushes by canonical digest only
|
||
# (push-by-digest=true). Unreferenced manifests on quay can be reaped within
|
||
# ~1-2h, but backend-merge-jobs runs only after the *entire* per-arch build
|
||
# matrix drains (max-parallel: 8 × dozens of entries → ~2h+). Without an
|
||
# anchoring tag, the earliest digests are gone by the time `imagetools create`
|
||
# tries to read them, producing "manifest not found" merge failures.
|
||
#
|
||
# We tag the digest under our internal ci-cache image; quay does not GC tagged
|
||
# manifests. The user-facing manifest list still references the original
|
||
# digest in local-ai-backends. backend_merge.yml deletes the anchor tag after
|
||
# the user-facing manifest is published — see cleanup-keepalive-tags.sh.
|
||
#
|
||
# Required env:
|
||
# GITHUB_RUN_ID - current workflow run id (set automatically by GHA)
|
||
# TAG_SUFFIX - matrix entry's tag-suffix (e.g. -gpu-nvidia-cuda-12-vllm)
|
||
# PLATFORM_TAG - amd64 / arm64 / single (single = singleton matrix entry)
|
||
# DIGEST - canonical content digest from build step (sha256:...)
|
||
#
|
||
# Optional env:
|
||
# ANCHOR_IMAGE - target image (default: quay.io/go-skynet/ci-cache)
|
||
# SOURCE_IMAGE - source image (default: quay.io/go-skynet/local-ai-backends)
|
||
# GITHUB_STEP_SUMMARY - if set, an anchored-by line is appended to it
