Add an alert-gate presubmit that runs aro-hcp-tests merge-gate, which asks the release dashboard whether the PR should merge given production alerts. The job always runs but is optional (non-blocking) while the gate is stabilized.

Summary by CodeRabbit

  • Adds an always-running, non-blocking alert-gate presubmit to the Azure/ARO-HCP CI pipeline.
  • Runs aro-hcp-tests merge-gate against the release dashboard to check production alerts before merge.
  • Adds the step definition, ownership, metadata, command, resource settings, timeout, and documentation.

Walkthrough

The change adds an ARO HCP alert-gate CI step. The step runs the merge-gate test with the release dashboard URL and is added as an optional job in the Azure ARO HCP pipeline.

Changes

ARO HCP alert-gate

Layer / File(s) Summary
Define the alert-gate step
ci-operator/step-registry/aro-hcp/alert-gate/*
The new step runs test/aro-hcp-tests merge-gate with ${RELEASE_DASHBOARD_URL}, defines resource requests and a 10-minute timeout, and adds metadata and ownership entries.
Wire the step into the pipeline
ci-operator/config/Azure/ARO-HCP/Azure-ARO-HCP-main.yaml
The Azure ARO HCP test pipeline invokes the optional aro-hcp-alert-gate test reference.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files. (4 skipped: 4 unsupported.)

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request adds CI configuration, ownership metadata, a shell wrapper, and a step-registry definition. The diff contains no Ginkgo test-title APIs such as It, Describe, Context, or When, and no dynamic test title construction. The added CI names (alert-gate and pull-ci-Azure-ARO-HCP-main-alert-gate) are static configuration identifiers, not Ginkgo test titles.

Full details: Test Structure And Quality

Explanation

PASS — the custom check targets Ginkgo test code, but this pull request changes no Ginkgo or test-source files. The commit adds CI YAML, ownership metadata, and a Bash wrapper that invokes the existing test/aro-hcp-tests merge-gate binary. It adds no It blocks, cluster operations, Eventually/Consistently calls, setup/cleanup, or assertions to review.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request adds CI configuration and a shell step that invokes test/aro-hcp-tests merge-gate; it does not add new Ginkgo It, Describe, Context, or When tests. The added files contain no MicroShift-incompatible OpenShift API, namespace, or unsupported platform assumption. The generated presubmit job only runs the optional alert-gate step.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request adds CI configuration, a generated presubmit job, ownership metadata, and a shell step that runs test/aro-hcp-tests merge-gate. The committed diff adds no Ginkgo e2e tests (It, Describe, Context, or When) and no multi-node or HA test assumptions. The SNO compatibility check is therefore not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request adds CI configuration, a step-registry reference, ownership metadata, a shell command, and a generated Prow presubmit job. It does not add or modify a deployment manifest, operator code, or controller. The generated job only adds a container, volumes, resources, and status.podIP; the diff adds no affinity, topology spread, replica, PDB, node selector/affinity, taint, or toleration constraints. No stated topology-scheduling failure condition is introduced.

Full details: Ote Binary Stdout Contract

Explanation

No OTE stdout contract violation is introduced. The pull request changes zero Go files and adds no process-level Go code, logging, Ginkgo setup, or stdout writes. The new script enables Bash xtrace, which writes to stderr, then invokes the existing aro-hcp-tests merge-gate command. The generated job runs this as a direct CI step, not as an openshift-tests test-listing process.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

The new alert-gate test step requires external connectivity. Its default URL is https://api.releases.dev.aro.azure-test.net, and the command posts JOB_SPEC to the release-dashboard merge-gate API. The generated job runs always and is only optional, so it still runs in CI. The change adds no IPv4-specific code, but the external API requirement violates disconnected-network compatibility.

Resolution

IPv6 and disconnected network compatibility notice: This test may contain IPv4 assumptions or external connectivity requirements that will fail in IPv6-only disconnected environments. Please verify your test works on IPv6 by running an additional CI job: For parallel tests: /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-ovn-ipv6 For serial tests (test name contains [Serial]): /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-serial-ovn-ipv6 Use an internal, mirrored release-dashboard endpoint for disconnected jobs, or skip this test in disconnected environments with the applicable [Skipped:Disconnected] mechanism. Verify the endpoint and its DNS path do not require public internet access.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request adds CI configuration, ownership metadata, a Bash wrapper, and a step definition. The changed command only invokes test/aro-hcp-tests merge-gate --url "${RELEASE_DASHBOARD_URL}". The diff contains no MD5, SHA1, DES, 3DES, RC4, Blowfish, ECB, custom cryptography, or secret/token comparisons. Secret volume references in the generated job only configure CI credentials and do not perform cryptographic operations.

Full details: Container-Privileges

Explanation

No custom-check privilege condition is introduced. The new step reference has no privileged, host namespace, capability, security context, runAsUser, or allowPrivilegeEscalation setting. The generated Kubernetes job also has no pod or container security context. The command only runs merge-gate. Existing USER root entries are unchanged build definitions and are not part of the added alert-gate step.

Full details: No-Sensitive-Data-In-Logs

Explanation

No sensitive data logging is introduced. The new set -o xtrace traces only the merge-gate command and its configured URL. The URL is a public HTTPS endpoint, not a password, token, API key, PII, session ID, or customer data. JOB_SPEC is consumed by the test binary and is not expanded by the shell trace. The changed files contain no secret-bearing command arguments or logging statements.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Disable command tracing in this step.

set -o xtrace writes the expanded RELEASE_DASHBOARD_URL to CI logs. Remove tracing and use the repository default.

Proposed fix
-set -o errexit
-set -o nounset
-set -o pipefail
-set -o xtrace
+set -euo pipefail

As per coding guidelines, step registry command scripts must default to set -euo pipefail without -x and must not leak environment-specific URLs into CI logs.
