As of openshift/cluster-version-operator#1466, the cvo will already have a default update service url, so we need to remove the override for OKD

Summary by CodeRabbit

  • Configuration
    • Standardized ClusterVersion channel configuration across all deployments.
    • Removed SCOS-specific update graph and channel settings.

📝 Walkthrough

Walkthrough

The ClusterVersion override template now always sets channel from .CVOChannel. It removes the SCOS-specific CI graph upstream and stable-scos-4 channel.

Unconditional CVO channel selection
data/data/manifests/bootkube/cvo-overrides.yaml.template
The template removes the .IsSCOS branch and uses .CVOChannel for all configurations.

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.

Full details: Stable And Deterministic Test Names

Explanation

The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template. It adds no Ginkgo test declarations or test titles. The removed lines only change ClusterVersion update-service configuration.

Full details: Test Structure And Quality

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template, removing five YAML template lines. The committed diff contains no Ginkgo test files and no It, BeforeEach, AfterEach, Eventually, or Consistently changes. Therefore, this test-structure check is not applicable.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template. The diff removes SCOS-specific ClusterVersion template fields and adds no Ginkgo tests or test declarations. The MicroShift Test Compatibility check is therefore not triggered.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only the ClusterVersion configuration template. It removes the SCOS upstream and channel conditional and retains spec.channel from .CVOChannel. The verified diff adds no workloads, replicas, affinity, topology spread constraints, node selectors, tolerations, or PDBs. Therefore, it introduces no topology-dependent scheduling constraint.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template, removing five YAML template lines. It adds no OTE binary code, suite setup, initializer, or process-level stdout write. The OTE Binary Stdout Contract is not violated.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template. The diff removes an SCOS update URL and channel conditional. It adds no Ginkgo e2e test and introduces no IPv4 assumption or external connectivity requirement in a test.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template. It deletes the SCOS update-service and channel block and retains channel: {{.CVOChannel}}. The parent-to-HEAD diff contains no additions involving MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret/token comparisons. Therefore, this pull request introduces no weak-crypto usage.

Full details: Container-Privileges

Explanation

PASS. The commit changes only data/data/manifests/bootkube/cvo-overrides.yaml.template and deletes the SCOS upstream and channel override. It introduces no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root user setting. The resulting ClusterVersion manifest contains no container privilege configuration.

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

Explanation

PASS: The pull request changes only data/data/manifests/bootkube/cvo-overrides.yaml.template. It removes the SCOS update URL and channel branch, then retains configuration fields for CVOChannel, CVOClusterID, and capabilities. The changed template contains no logging statements and does not add passwords, tokens, API keys, PII, session IDs, hostnames, or customer data to logs.

Add unit coverage for both CVO channel outcomes.

pkg/asset/manifests/operators_test.go contains only redaction tests and does not cover generateBootKubeManifests. Add assertions for stable-scos-<major> on SCOS installations and stable-<major>.<minor> on non-SCOS installations.

This is the only template consumer of IsSCOS, right? If so, you can probably drop this and maybe more.
