HYPERFLEET-1582 - docs: Image delivery for the CAPOCI Controller and the OCI Cloud Controller Manager - #216
Conversation
…ion decision Decide how the CAPOCI controller image and the OCI cloud controller manager image are delivered, since neither is in the OpenShift release payload. Both resolve by one precedence -- annotation > environment variable > compiled digest-pinned default -- via two mechanisms that already exist upstream: the CAPI provider pattern for CAPOCI, and a synthetic payload tag injected through the control plane operator's existing --image-overrides for the cloud controller manager. The latter keeps the image inside the registry override channel, which is the only mirroring lever on a vanilla OKE management cluster. Delivery is staged: Oracle's Apache-2.0 upstream images pinned by manifest list digest now, with a Konflux rebuild required before GA to satisfy the app-interface-standard Enterprise Contract policy. Unblocks HYPERFLEET-1547 and HYPERFLEET-1552. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

📝 SummarySummary by CodeRabbit
WalkthroughADR-0025 now defines OCI operand sourcing and supply-chain rules. It specifies digest-pinned defaults, HyperFleet-owned Konflux builds for GA, compatibility requirements, mirrored pullspecs for disconnected installs, and exclusion from the release payload. The ADR index uses the new title. The glossary adds CAPOCI and Release Payload entries and requires digest-pinned explicit operand-image overrides. Priority: ⬇️ Low Estimated code review effort: 1 (Trivial) | ~5 minutes Change: Other Suggested reviewers: Merge Risk: 🟡 Moderate · up to The OCI CCM delivery contract can be implemented with a mutable image tag, defeating the stated immutable-image and disconnected-mirroring requirements.

- Around line 52-56: Clarify the ADR’s digest-pinning contract for explicit
CAPOCI and OCI cloud controller manager image overrides: require
disconnected-installation overrides to use digest-pinned pullspecs, or
explicitly limit artifact image inventories to shipped defaults and exclude
customer-selected overrides.
In `@hyperfleet/docs/glossary.md`:
- Line 30: Update the visible ADR citations in the affected glossary entries,
including the CAPOCI entry and the entries at the referenced locations, from
ADR-0023 to ADR-0025 while keeping their existing
0025-oci-operand-image-delivery.md links unchanged.
- Line 70: Update the OKE glossary entry to document the disconnected-image
rules separately: OCI cloud controller manager images may use HyperShift
registry rewriting or an explicit override, while CAPOCI requires an explicit
override to its mirrored pullspec and does not support registry rewriting.
Replace the generic registry-overrides wording without changing the surrounding
OKE description.

The research holds up. The issue is underneath the document: 548 is a child of HYPERFLEET-164, which is paused pending the approach decision, and the Decision section presumes a first-class OCI platform type upstream. ADR-0021 scoped itself to the guest layer and parked that question (its line 13), so it was assumed rather than decided.
Suggest we narrow rather than park this. The image source, digest pinning and disconnected contract hold under any approach and are worth landing now. The resolution mechanism moves to a follow-up ADR that cites this one once the platform decision lands. Inline comments mark which is which.
Retitle to something like "image sourcing and supply chain for the OCI operands", keep Status: Active, and add a line saying the mechanism is deliberately deferred.

| - HyperFleet keeps the user override in the existing `hypershift.openshift.io/image-overrides` annotation as `oci-cloud-controller-manager=<pullspec>`. | ||
| - For OCI clusters, HyperFleet automatically supplies an OCI cloud controller manager image to HyperShift through the existing `image-overrides` mechanism. It uses `IMAGE_OCI_CLOUD_CONTROLLER_MANAGER` if set; otherwise it uses the compiled digest-pinned default. | ||
| - For the OCI cloud controller manager image, user overrides take precedence over `IMAGE_OCI_CLOUD_CONTROLLER_MANAGER`, which in turn takes precedence over the compiled default. | ||
| - HyperFleet provides the OCI cloud controller manager image through HyperShift's existing image-resolution mechanism rather than hardcoding it in the component manifest, so existing override and mirroring behavior continues to apply. | ||
| - If HyperFleet cannot resolve an OCI cloud controller manager image, it must fail during rendering rather than later at deployment time. |

Drop the section. The image-overrides path presumes an OCI component in the CPO. Line 38 is a good requirement, carry it to the follow-up: HyperShift sets ValidReleaseInfo only after rendering, so a missing key today produces a Deployment with an empty image rather than a render failure.

Keep as-is, this is the core of the narrowed ADR. One gap: line 46 commits to HyperFleet-owned Konflux builds and nothing names the component, registry or release wiring, which is AC3 on HYPERFLEET-1582. Without an owner the Oracle digests become the GA defaults by default, which line 96 rejects.

Drop 101 and 102 with the mechanism. For 103: HYPERFLEET-1412 is Closed (resolved 11 Sep), 1411 is in Review, and 1569 is scoped to the HyperShift, CPO and release image triple, so none of the three will pick this up. Worth noting 1412's relatedImages gate checks images the operator deploys, and neither of these is, so both can go missing silently. Needs an open, in-scope owner.

| HyperFleet treats both OCI images as non-payload operands. HyperFleet ships a compiled digest-pinned default for each image. For first shipped support, those defaults are Oracle-published manifest-list digests. For GA / released OCI support, those defaults must move to HyperFleet-owned Konflux builds from the same upstream sources. Both images remain outside the OpenShift release payload in either phase. | ||
|
|
||
| - CAPOCI controller: the selected image, vendored CAPOCI version, and shipped CAPOCI CRDs must stay aligned. Installation-time overrides are limited to digest-pinned mirrors of that aligned image; they must not change the CAPOCI version independently. | ||
| - OCI cloud controller manager: the selected image must remain compatible with the Kubernetes minor of the hosted OpenShift release. OpenShift 4.20 uses Kubernetes 1.33, so the first default pin is `v1.33.x`. |

Do not use v1.33.x as the image pin.
The ADR requires a compiled digest-pinned default, but this line calls the compatibility range v1.33.x the first default pin. If an implementation uses it as the default reference, the image can change without a digest or inventory update, and disconnected mirroring cannot identify one immutable artifact (CWE-494). Keep v1.33.x as the compatibility criterion and define the default as a manifest-list digest for a compatible image.
Proposed wording
- OpenShift 4.20 uses Kubernetes 1.33, so the first default pin is `v1.33.x`.
+ OpenShift 4.20 uses Kubernetes 1.33, so the first default must be a manifest-list digest for an image compatible with Kubernetes 1.33. `v1.33.x` is the compatibility range, not the image reference.📝 Committable suggestion
