Merge Risk: 🟡 Moderate · up to This change moves pre-releases to multi-architecture image publishing, but several release-pipeline issues remain open. Pinned references could be rewritten to the wrong repository's index. The E2E audit could check stale image lists. Stable-tag audits could fail when they should only warn. Release preparation still has credential and toolchain-pinning gaps. Resolve these before relying on the new release flow. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new checks substantially strengthen multi-architecture releases, but two release-integrity boundaries merit review: digest rewriting can lose image-repository identity under a shared-digest condition, and the audit of images actually pulled during testing runs after a release candidate is published.

Without --raw, skopeo inspect resolves a multi-arch index to the child manifest for the host platform and reports that digest. The tree pins the index digest, so once main publishes indexes every mirrored image would fail its own post-copy verification. Hash the raw manifest instead, which is the digest the tree pins for an index and a single manifest alike. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>
A native arm64 leg builds the same images next to the amd64 build and must not overwrite the cache that build owns. CACHE_TAG moves the default cache ref, so the leg can write buildcache-arm64 without every write evicting the amd64 cache layers, and without a change to each package Makefile. An explicit per-call cache tag still wins. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

The release gate reads only refs the tree pins by digest, so an image a vendored chart renders from its defaults, or one an operator launches, can still be amd64 only. The rc e2e now reads what the three Talos nodes actually pulled from their image stores, each by the digest the pull resolved to, and runs verify-multiarch on that list before the sandbox is torn down. The image store, not the running pods, because the tests delete what they create. collect-images.sh writes that list only when every node answered, so a node that could not be read fails the audit instead of passing the images only it held. A pre-release fails on the audit; a stable tag's run only warns, as it ships its rc's images unchanged. The audit runs in the tree of the tag under test, so a tag cut before it existed has neither the script nor the image list. That run warns and skips instead of failing, so such an rc can still be re-validated from main; a tree that has the script and no list still fails.

Reviewed statically in a hermetic clone. Ran the bats suites that completed (build-matrix, common-envs, nightly-mirror, collect-images, all green) and traced the stitch and verify-multiarch logic by hand where the heavy multi-arch builds could not finish locally. Code LGTM. Minor non-blocking notes only. Leaving the hold and the Merge after ordering to you.
The base branch was changed.

Handle tool installation failure under the stable-tag policy.
If either tool is missing and apt-get fails, the audit step exits before the status branch. A stable-tag E2E job then fails instead of reporting an audit warning. Capture installation failure as an audit failure and pass it through the existing prerelease-versus-stable handling.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Narrow the "not found" match in manifest_digest.
The pattern manifest unknown|not found|404 also matches unrelated failures. Examples are repository name not known variants, no such host-style messages that contain "not found", and credential helper errors such as credential helper not found. In each of these cases the function returns an empty digest and a zero status. On line 207 the caller then treats the empty digest as "no arm64 image" and skips the image. The run succeeds, and the image stays amd64-only. The skip still prints a warning, and verify-multiarch.sh fails the rc later, so the release does not ship broken. The operator still gets a misleading reason. Match only the registry's manifest-unknown answer.
Proposed fix

Remove the host reference file before each collection.
If a previous collection created _out/image-refs.txt and a later node read fails, hack/collect-images.sh removes only the sandbox copy. The new docker cp fails, but the old host file remains. The workflow ignores the collection failure and can audit the old list instead of the images from the current run. Remove the host file before docker exec, then copy only a newly produced file.

…unlisted images for arm64 (#4552) ## What this PR does This brings together four approved PRs that give the remaining first-party images an arm64 build. Each of them lost its approval when #4498 merged and GitHub retargeted it to main, so I merged them into one branch to review and approve once. Each original PR has the full description and review history, and I'll close them in favour of this one. - #4507 builds the Talos installer and matchbox for arm64. Releases also publish the arm64 ISO, disk images, kernel and initramfs. - #4515 builds the KubeVirt Velero plugin in-tree for amd64 and arm64. - #4525 adds flux-plunger, keycloak-operator, kilo and migration-controller to the root `build:` list, so CI rebuilds them like every other image. A test keeps any new image target from being left out. - #4528 rebuilds the Harbor v2.15.1 images for amd64 and arm64, because upstream publishes v2.15 for amd64 only. Release builds still run with `PLATFORM=linux/amd64`, except the Talos installer, so these images ship arm64 only once #4505 adds the arm64 leg. This PR makes that leg buildable. A few commits are new on top of the originals. The velero test no longer pins the plugin's image string, because the release build stamps its own rebuild over it. It now checks the plugin init container by repository name. A promote-retag test comment now says what it guards, and the image-refs doc no longer calls its fixed gaps open. The merge with main keeps the Harbor portal in the list of stages whose output has no architecture. ### Screenshots Not a UI change. ### Downstream repositories I left every box empty and opened nothing in other repositories. Two repositories are touched, and neither follow-up is needed before this merges: - cozystack/website names the amd64 assets in `content/en/docs/next/install/talos/iso.md` and `install/providers/oracle-cloud.md`. The install pages could offer the arm64 downloads once a release carries them. No asset is renamed, so the current links keep working. - cozystack/talm points at `ghcr.io/cozystack/cozystack/talos:<version>` in `charts/cozystack/values.yaml`. Once a release publishes that tag as a two-arch index, the same reference works on arm64 nodes, so nothing there has to change. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(talos): the Talos installer image is built for amd64 and arm64, with arm64 profiles that carry drbd and zfs, and the bootbox matchbox image network-boots arm64 machines as well as amd64 ones. Releases publish the arm64 Talos ISO, disk images, kernel and initramfs. feat(velero): the KubeVirt Velero plugin is now built in-tree for amd64 and arm64, so the velero server starts on arm64 clusters. build: flux-plunger, keycloak-operator, kilo and migration-controller are now rebuilt by CI like every other first-party image, so their pinned images pick up source patches and base-image updates and are published for amd64 and arm64. feat(harbor): the Harbor application now runs on arm64 nodes. Its component images are rebuilt from the pinned upstream v2.15.1 release for amd64 and arm64, because upstream publishes v2.15 images for amd64 only. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Talos images and boot assets now support both AMD64 and ARM64, including architecture-specific installation and cloud images. * Added build support for Harbor components and the KubeVirt Velero plugin. * Nightly builds now include ARM64 release assets. * **Improvements** * Harbor uses pinned chart and image versions, with built image references recorded automatically. * Added checks to catch image packages missing from the main build and to verify multi-architecture installer output. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Disable persisted checkout credentials in prepare-release.
build-amd64 disables persisted credentials, but the prepare-release checkout does not. GitHub Actions therefore stores GITHUB_TOKEN in .git/config as an extraheader before running the stitch and image build commands. Those commands run on the patched tree and can access the token. Set persist-credentials: false for this checkout. The later push steps configure their own APP_TOKEN remote URL.

Pin the flux version in prepare-release.
build-amd64 installs flux pinned to FLUX_VERSION: "2.8.6". This step pipes the unpinned install.sh straight into sudo bash, so it installs the latest flux release. make ... image-packages republishes the packages artifact with that flux. The republished artifact can then be built with a different flux than the one used to build it. Reuse the same pinned install that build-amd64 uses.

matchbox already carries the kernel and initramfs of both arches, but the release built it for amd64 only: the arm64 leg skips the talos package, so there is no arm64 half to stitch, and the gate let it through on an allowlist entry. Its Dockerfile only copies files, so the amd64 job now rebuilds it for both platforms on a docker-container builder and the stamped ref pins the index. The allowlist entry goes.

tags.yaml only runs on tags, so no pull request exercises it. The matchbox rebuild is the only thing that makes its ref an index, and losing the step, moving it past the tree capture or letting it switch the default builder would surface as a failed gate on the next rc. The comments that called the talos images amd64 only now say they are built for both arches in the amd64 job. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

Scope digest replacement to the repository.
If two repositories pin the same amd64 digest but have different arm64 images, this replacement changes both repositories’ references to the first repository’s index digest. The second repository’s pass then cannot correct its references because the original digest is gone. Those references can point to an index absent from their repository. Match the repository as well as the digest in both the plain-file and gzip rewrites. Keep the leftover check scoped to the repository being stitched.

Review comment at @hack/stitch-multiarch.sh at line 251:
Update the replacement in the per-digest rewrite flow around `sed` to match both
the repository and the digest in plain-file and gzip rewrites, so only
references belonging to the repository being stitched change. Keep the leftover
check scoped to that same repository.

…n rc The amd64 release job builds the Talos installer and matchbox for both arches, so the pages that said CI never builds both in one job, and that build-amd64 builds amd64 only, were wrong. Every rc stitch also skips matchbox and the e2e sandbox, and the nightly report lists matchbox and the refs an in-tree rebuild stamps over; the page said every such skip and line fails the next rc. Name the ones that do not. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>
The release job now builds the Talos installer for both arches, so _out/assets holds an arm64 tarball next to the amd64 one. Both are the image the build pushed, not something upload-assets publishes, and the artifact only excluded the amd64 one. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>
prepare-release now runs flux push artifact to publish the rc's packages artifact, and it installed whatever flux was latest, while build-amd64 and the candidate checks pin one version. It installs that version now. The arm64 leg and the nightly never run flux, so they no longer install it. The rc-e2e comment gave a stable tag as the reason for its !cancelled(), but the job only runs for an rc; it now says it follows the rule every job below build-arm64 has.

Verdict
LGTM with non-blocking notes
This is release-tooling only. The single cluster-facing change (the keda and kuberture values) renders byte-for-byte identical at merge-base and at head: the added registry/repository equal the subchart defaults and exist only so the digest-pinned ref is complete in the file the release tooling reads. Every release gate fails closed, and the whole pipeline first runs after merge, by design. Tested against origin/main (b314514950); the only drift on main since this branch is an unrelated chart bump.
Four notes below, none blocking. Each one fails a release closed rather than shipping a single-arch image, so the failure direction is a blocked release, never a bad ship.
What I checked
- Both charts render identically base to head (
helm template). - Gates fail closed: a
jq/parse error aborts underset -e(confirmed in dash and bash); a rate-limited or unreadable ref lands inbad, never a silent skip; the e2e auditexit 1s for any*-*tag and warns only for stable, which inherits its rc indexes. Neutering theverify-multiarchexit reddens 4 of its 8 own tests, so the suite is not vacuous. - All six new or edited bats suites pass offline.
collect-images.shfailing on an unreadable node leaves noimage-refs.txt, which fails the pre-release audit closed.
Findings
- [MINOR]
.github/workflows/tags.yaml:362, "Re-run all jobs" on a failed rc hits a 409 on the immutable v4 artifact
- [MINOR]
hack/stitch-multiarch.sh:101, manifest_digest treats any stderr containing "not found"/"404" as "image absent"
- [MINOR]
.github/workflows/e2e-tag.yaml:336, the audit and the release gate hit docker.io anonymously, a new rate-limit flake source
First-run risks and smaller notes
Static review cannot settle these; they run for the first time on the next nightly and rc, against live registries:
- The arm64 build itself, the stitch against real registries, and whether
talosctl images lson the x86 sandbox reports the pulled index digest or the amd64 child. If it reports the child, the audit over-blocks every multi-arch image, which is again a blocked release rather than a bad ship. -beta.Nand-alpha.Ntags get the static gate but not the runtime audit (rc-e2eruns only for-rc.); stable inherits from a fully-audited rc.- Disclosed in the PR body: an image neither pinned in the tree nor pulled in e2e is covered by neither gate. That is an improvement over the prior single-arch state, not a regression.
NIT: each rc leaves roughly fifty vX.Y.Z-rc.N-arm64 tags in GHCR that the stitch does not move and neither promote-retag.sh nor nightly-mirror.sh ever touches. Cosmetic, but they accumulate in the package UI over time.

[MINOR] "Re-run all jobs" on a failed rc hits a 409 on the immutable v4 artifact
actions/upload-artifact@v4 artifacts are immutable within a run and the default overwrite is false. If an rc run fails inside prepare-release before the draft is created (so release_exists stays false), "Re-run all jobs" re-runs build-amd64, which rebuilds and re-pushes every image (moving the rc and component tags back onto amd64-only), and then this upload step fails with 409 Conflict: an artifact with this name already exists on the workflow run. The job goes red, prepare-release is skipped, and the images are left single-arch until a clean run. Only "Re-run failed jobs" works, which the comments imply but do not state. overwrite: true on both upload steps would make "Re-run all jobs" work too. Non-blocking: the release still fails closed.

[MINOR] manifest_digest treats any stderr containing "not found"/"404" as "image absent"
grep -qiE 'manifest unknown|not found|404' classifies a missing manifest, but it also matches unrelated skopeo errors, e.g. a credential-helper failure (executable file not found in $PATH) or a network resolution error. Such an error would return empty, print skipping <name>: no <tag>-arm64 image for every image, and rewrite nothing. This is not a silent single-arch ship: verify-multiarch.sh runs right after with the same skopeo and fails the release closed. The cost is a misleading diagnosis in the log ("no arm64 image" instead of the real error) across ~50 warnings. On these ephemeral runners the credsStore trigger is unlikely (login-action writes a plaintext auth to runner.temp/.docker), so this is a latent robustness note rather than a live bug. Narrowing to skopeo's own phrasing (manifest unknown, MANIFEST_UNKNOWN, NAME_UNKNOWN) and returning non-zero on anything else would remove the ambiguity.

[MINOR] the audit and the release gate hit docker.io anonymously, a new rate-limit flake source
The e2e audit here and the Stitch multi-arch indexes and republish gate in tags.yaml both read registry manifests with skopeo directly against docker.io, with no login and no mirror, while node pulls go through mirror.gcr.io (hack/e2e-prepare-cluster.bats) and buildkit through hack/buildkitd.toml. The tree pins docker.io refs (goharbor, grafana, otel, busybox, clastix, alpine/k8s), and the e2e pulled-image list has more. Anonymous docker.io is rate-limited to 100 pulls per 6h per IP, and inspect --raw counts; the Oracle runner pool shares a NAT IP. For a pre-release this is exit 1 (fail-closed, correct), but it is a new flake source on shared infrastructure. A skopeo login docker.io in both steps, or substituting mirror.gcr.io for docker.io/ refs, would remove it.

What this PR does
Pre-release builds now publish every image as an amd64 and arm64 index, and a release fails if anything it ships is single-arch. Main, release lines and pull requests keep building amd64 only. It builds on #4498, which made every image buildable for both architectures. Part of #1961.
This PR is on hold until everything under "Merge after" has landed. Merged earlier, the new gate fails the next rc on the images those PRs fix.
How a pre-release is built
A pre-release tag gets a second job, for arm64, next to the existing release job. That covers
-rc.N,-beta.Nand-alpha.Ntags. It runs on the CNCF arm64 pool (oracle-vm-24cpu-96gb-arm64), builds the same images withPLATFORM=linux/arm64, and pushes them as<tag>-arm64.prepare-releasewaits for it, and if the arm64 job fails the rc fails with it. There is no amd64-only fallback. Stable tags do not run it: promotion copies the rc digests withskopeo copy --multi-arch all, so a stable release inherits the indexes.After the amd64 build, the stitch joins each amd64 image with its arm64 twin into one index. It lives in
hack/stitch-multiarch.sh. Every tag of the amd64 image moves to the index, the component-versioned ones included. The script then rewrites the digests in the tree and republishes the packages artifact and the installer chart pinned on them. It reads refs throughhack/lib/image-refs.sh, and it fails if an old digest survives anywhere outsidecharts/.The gate
A new check fails the rc when a pinned digest in the tree is not an index with both linux/amd64 and linux/arm64. It lives in
hack/verify-multiarch.sh. It checks first-party and third-party refs alike. Images that are amd64 by nature go intohack/multiarch-allowlist, one repository per line, each with a mandatory reason. Today that is only the e2e sandbox. An entry that matches nothing is reported as stale.The static gate only sees digest-pinned refs in the tree. A tag-only ref, an image from a vendored chart default, or one an operator starts at runtime is invisible to it. So the rc e2e also audits every image its nodes pulled, with the same check and the same allowlist. Neither covers a package the e2e never installs.
Nightly
A new nightly workflow builds main for arm64. It keeps the arm64 build cache warm, since the rc job only reads it. It also prints the single-arch refs that would block the next rc. Nothing it builds is published.
Smaller changes
CACHE_TAGinhack/common-envs.mkmoves the default cache ref, so the arm64 build keeps a cache of its own.MATRIX_ARCH=arm64makeshack/build-matrix.shleave out the amd64-only e2e sandbox.IMAGE_TAGlike every other image. Its Makefile setIMAGE_TAGitself, so concurrent builds overwrote each other's component tag. Closes capi-providers-cpprovider: every build pushes over the kamaji provider's release tag, and a second tag ends in a bare dash #4503.hack/nightly-mirror.shverifies a copy against the raw manifest digest. Plainskopeo inspectresolves an index to one platform's child.The stitch also rewrites the kamaji ref inside
files/components.gz, recompressed withgzip -nso the bytes are reproducible, so the kamaji control-plane provider ships multi-arch too. keda and kuberture now name the repository next to their pinned digest, so the gate can resolve them; their rendered manifests do not change.Merge after
build:list. It replaces feat(talos): build the Talos installer and matchbox for arm64 #4507, feat(velero): build the KubeVirt plugin image for amd64 and arm64 #4515, build: rebuild every package that has an image target #4525 and feat(harbor): build the Harbor images for amd64 and arm64 #4528.The rest of the stack is merged: #4485, #4498, #4512, #4517, #4521 and #4522 here, and the multi-arch PRs in ingress-nginx-with-protobuf-exporter, cozy-proxy, cozystack-scheduler and keycloak-kms-proxy.
Verification
The bats suites pass: stitch, verify-multiarch, build-matrix, common-envs, nightly-mirror and the release contracts. The first three also pass under
hack/cozytest.shwith dash. Each new test was red before its implementation, and the verify-multiarch and stitch tests each have a mutation that turns them red. I ranverify-multiarch --reportagainst main. It lists the first-party refs the stitch will fix, plus the third-party and special cases above. The workflows have not run yet. The arm64 job's tools and duration, the stitch against real registries, and the audit are checked for the first time on the nightly and on the next rc.Screenshots
Not a UI change.
