Add disconnected cluster testing pipeline - #171
Conversation
📝 WalkthroughWalkthroughAdds a Tekton pipeline for disconnected OpenShift testing. It provisions a mirror registry, mirrors required images, installs the operator, controls node network access, runs tests, and performs conditional cleanup and Report Portal upload. ChangesDisconnected testing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new pipeline can run tests with incomplete network isolation, fail because required images remain external, mis-handle setup or cleanup commands, lose uploaded results, or leave cluster networking and mirror configuration in a bad state. These are high-impact current-head correctness and recovery risks, so the PR is not ready to merge until they are fixed. Sequence Diagram(s)sequenceDiagram

Order the finally tasks so that cleanup cannot delete results before the upload.
Tekton runs all finally tasks in parallel, and runAfter is not permitted in finally. disconnected-cleanup removes disconnected test resources and workspace files, and rptool-upload reads the test results from the same shared-workspace. If disconnected-cleanup deletes result files, rptool-upload can upload an incomplete launch or fail.
Confirm which workspace paths disconnected-cleanup deletes. If it touches the results directory, restrict it to the disconnected artefacts only, or move the reconnect and cleanup steps into the rptool-upload ordering by combining them in a single finally task.

Do not overwrite the iptables backup on repeated runs.
Line 66 saves the current rules every time the task runs. If the task runs disconnect twice on the same node without an intervening reconnect, the second run saves the already-blocked ruleset. reconnect and disconnected-cleanup then restore the blocked rules, and the node stays disconnected after the pipeline ends.
Write the backup only when it does not exist yet.

Block IPv6 egress as well.
The script only changes the IPv4 OUTPUT chain. On a dual-stack cluster, nodes keep IPv6 egress to registry.redhat.io and quay.io. The test then runs against a cluster that is not fully disconnected, and the connectivity check at Line 124 still reports "BLOCKED" because curl -I https://quay.io can succeed over IPv6 only if DNS returns AAAA records and the check uses the same path. This weakens the guarantee the pipeline is designed to provide.
Apply the equivalent rules with ip6tables, and save and restore the IPv6 ruleset in the same way.
Also consider adding the block rules into a dedicated chain instead of iptables -F OUTPUT. The flush removes the jump rules that OVN-Kubernetes and kube-proxy install in OUTPUT, which can disturb in-cluster traffic during the test window.

Fix the internal API check.
oc get --raw /healthz writes ok to stdout. The command substitution captures that body plus the echo "ok" output, so INTERNAL_TEST becomes okok. The comparison at Line 134 never matches, and the task always prints "FAILED - Internal access blocked!" even when the API server is reachable.

Fail the task when the cluster is not disconnected.
The disconnect branch prints a warning and exits 0 when DISCONNECT_OK is false. In pipelines/test/disconnected/pipeline.yaml (Lines 88-180), install-operator and run-tests run after cluster-disconnect with runAfter, so the disconnected test suite runs against a still-connected cluster and can report a false pass.
Exit non-zero when any node keeps external access.

Kubernetes imagePullPolicy Always image digest resolution when the registry is unavailable and the image is already cached
💡 Result:
When imagePullPolicy is set to Always, the Kubernetes kubelet instructs the container runtime to reach out to the image registry every time a container is launched to resolve the image tag or name to a specific digest [1]. Because this step is a required part of the container startup process, if the registry is unavailable, the image resolution will fail, and the pod will be unable to start—even if the exact image version (the resolved digest) is already cached locally on the node [2][3][4]. The process follows these steps: 1. The kubelet delegates the pull request to the container runtime [1]. 2. The container runtime must contact the remote registry to verify the image digest for the specified tag [1][5]. 3. If the registry is unreachable, the runtime cannot perform this verification, resulting in an error (often reported as RegistryUnavailable) [3]. 4. Consequently, the container will fail to start [3]. Although the container runtime is capable of using a cached image if it matches the resolved digest, it cannot skip the initial handshake with the registry when the policy is set to Always [1][6]. This design ensures that the cluster always verifies the latest image manifest and maintains authentication requirements, but it effectively turns the image registry into a critical dependency for pod startup [5][2][4].

imagePullPolicy: Alwayskubernetes/kubernetes#90809
Make all post-disconnection images available inside the cluster.
imagePullPolicy: Always requires registry access when disconnected-install-operator starts. Mirror quay.io/kuadrant/testsuite-pipelines-tools before cluster-disconnect and reference an immutable digest from the in-cluster registry. Apply the same change to the post-disconnection run-tests and cleanup tasks. Pre-pulling the external :latest image alone does not remove this registry dependency.

The mockserver image is still hardcoded to a personal quay namespace.
quay.io/rhn_support_azgabur/mockserver:latest ties the pipeline to a personal repository and a mutable latest tag. Expose it as a task parameter with a shared default, and pin the digest or a version tag so the mirrored content is reproducible. Previous reviews already raised the hardcoding of mirrored images.

Unguarded command substitutions abort the step under set -e. Both sites capture oc output without a fallback, so a transient or expected API failure ends the task instead of following the intended error path.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not append fallback output to count-producing pipelines.
grep -c and wc -l already emit 0 when appropriate, while their non-zero status can trigger || echo "0" and produce a multi-line value such as 0\n0. The resulting numeric comparisons fail or behave incorrectly. Apply a single-value fallback strategy to the pod counts here and to NODE_COUNT, PENDING_PODS, and TERMINATING_PODS in cleanup.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Guard the CatalogSource rename against an empty ORIGINAL_NAME.
The grep | head | awk pipeline exits 0 even when no name: line matches, so ORIGINAL_NAME can be empty. The sed command at line 536 then becomes s/name: /name: kuadrant-disconnected-operator-catalog/, which rewrites the first name: occurrence on every line of the manifest, including metadata.namespace neighbours and spec.image sibling keys that contain name: . The applied CatalogSource is then wrong, and the failure is hard to diagnose.
Fail early instead.

Adds a test-disconnected Tekton pipeline that validates RHCL operator installation on disconnected OpenShift clusters. The pipeline deploys an in-cluster mirror registry, uses oc-mirror v2 to mirror operator images and dependencies from registry.redhat.io, applies IDMS/ITMS configuration, disconnects cluster nodes from external network via iptables, installs the operator from the mirrored catalog, runs the testsuite disconnected target, and cleans up all resources (reconnecting the cluster, removing mirror sets, registry, and catalog sources) in a finally block.
