…tests" This reverts commit 72c5b0d.
The original PR openshift#1344 used runtime.GOARCH to detect architecture for the custom schema test's BuildConfig and CatalogSource nodeSelector. This broke arm64-only clusters because runtime.GOARCH returns the test binary's compile-time architecture (amd64), not the cluster's actual node architecture. Fix by querying a schedulable worker node's architecture via `oc get nodes -l node-role.kubernetes.io/worker` and falling back to runtime.GOARCH only if the node query fails.

WalkthroughThe test detects worker node architecture and passes it to custom catalog image builds and CatalogSource creation. BuildConfig, CatalogSource, and embedded Kubernetes templates now apply the architecture through ChangesArchitecture-aware OLM tests
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change improves architecture detection for multi-architecture clusters, but an unsuitable or missing worker-node result can still apply the wrong selector and leave required pods Pending until the test times out. Merge should wait for explicit handling of Ready, schedulable nodes and the empty-result case. Sequence Diagram(s)sequenceDiagram

- Around line 62-72: Update the architecture discovery logic around the
worker-node query to select a node that is Ready and schedulable, using its
kubernetes.io/arch value rather than assuming .items[0] or dedicated worker
nodes. Keep testArch set only when a suitable node is found; otherwise handle
the absence explicitly instead of silently relying on runtime.GOARCH, and
preserve the existing logging for detection or fallback.

Derive testArch from a Ready, schedulable node.
testArch becomes the kubernetes.io/arch selector for both the BuildConfig and CatalogSource. .items[0] can select a cordoned or NotReady worker, while an empty result falls back to runtime.GOARCH. This can leave the build or catalog pod Pending when no schedulable node has that architecture. Do not assume dedicated worker nodes. Handle the absence of a suitable node explicitly.

Summary
Re-applies #1344 (reverted in #1349) with a fix for arm64-only cluster support.
Problem
The original PR #1344 used
runtime.GOARCHto detect the cluster architecture and setnodeSelectorconstraints on the BuildConfig and CatalogSource pods. However,runtime.GOARCHis a compile-time constant that reflects the architecture the test binary was built for — not the cluster's actual node architecture.In multi-arch CI, the
openshift-testsbinary is cross-compiled for amd64 and runs on arm64 nodes via emulation. This causedruntime.GOARCHto returnamd64on arm64-only clusters, settingnodeSelector: kubernetes.io/arch: amd64which could never match any node — resulting in a permanent scheduling failure and test timeout.Fix
Replaces
runtime.GOARCHwith a cluster query that reads the actual architecture from a schedulable worker node:Falls back to
runtime.GOARCHif the node query fails.Validation
To validate on an arm64-only cluster (the environment where the original PR failed), run:
