OCPBUGS-112278: Add ConfigMap hash annotation to networking console plugin deployment by tpantelis · Pull Request #3131 · openshift/cluster-network-operator

tpantelis · 2026-08-21T14:47:38Z

When TLS parameters change, the nginx ConfigMap is updated but the pods don't automatically restart to pick up the new configuration. This adds a hash of the ConfigMap content as a pod template annotation, which triggers a rolling update when the ConfigMap changes.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

Summary by CodeRabbit

New Features
- Networking Console Plugin deployments now automatically track configuration changes through a generated configuration hash.
- Deployments update when TLS or other plugin configuration changes.
- Configuration changes are detected consistently from the rendered plugin configuration.
Bug Fixes
- Improved error handling when plugin configuration rendering, serialization, or hash generation fails.
- Added validation to ensure configuration changes produce a different deployment hash.

Walkthrough

The networking console plugin renderer hashes serialized ConfigMap manifests. The deployment pod template receives the hash as an annotation. Tests verify that TLS changes produce a different hash.

Changes

Networking console plugin rollout

Layer / File(s)	Summary
Generate configuration hash `pkg/network/render.go`, `pkg/network/render_test.go`	The renderer serializes the ConfigMap manifest and computes a SHA-256 hexadecimal hash. Errors return contextual failures. Tests verify hash generation and changes from TLS updates.
Apply hash to deployment pod template `bindata/networking-console-plugin/003-deployment.yaml`	The deployment pod template includes the generated configuration hash annotation.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to c938d

This localized change adds automatic pod restarts when the networking console plugin configuration changes, with no actionable merge-blocking risk remaining beyond normal checks and review.

Suggested reviewers: miheer, weliang1, bpickard22

Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

Ignore

❌ Failed checks (5 errors, 2 warnings)

Check name	Status	Explanation	Resolution
Pr Quality	❌ Error	The authored description is one paragraph: it lacks Why/What/Testing sections, CI lane/platform details, upgrade or rollback notes, and a bug link; the 60-line change is appropriately scoped.	Update the PR description with Why, What, Testing (automated CNO CI jobs and platforms), root cause, OCPBUGS-112278 link, user impact, and upgrade/rollback considerations.
Commit Message Quality	❌ Error	The sole PR commit is logical and has a useful body, but its scoped subject starts “Add” instead of an affected-component prefix; related commits use prefixes such as “frr-k8s:”.	Rename the subject with a component prefix, for example: “networking-console-plugin: Add ConfigMap hash annotation to deployment”.
E2e Tests For Feature Changes	❌ Error	The PR changes user-facing rendering behavior in pkg/network/render.go, but its diff has no test/e2e files and the description has no Testing or How to verify it section.	Add or modify test/e2e coverage and add the required testing section with CI lanes, platforms, and results. If E2E is not feasible, document why under How to verify it and follow the stated override process.
Ai-Generated Code Smell	❌ Error	The new test adds `// Render with different TLS config` immediately above the TLS assignment and render call; it merely restates the code and matches the explicit comment-slop condition.	Remove the redundant test comment, or replace it with rationale that explains a non-obvious testing requirement.
Title check	❌ Error	The title describes the change and uses the imperative mood, but it exceeds the 72-character limit at 85 characters.	Shorten the title to 72 characters or fewer while preserving the Jira key and the ConfigMap hash annotation change.
Docstring Coverage	⚠️ Warning	Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 2 functions across 2 files.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Test Structure And Quality	⚠️ Warning	The added test uses generic `NotTo(HaveOccurred())` assertions at lines 800 and 816 without failure messages, matching the check's explicit failure example.	Add meaningful context to both error assertions, such as `failed to render networking console plugin with initial TLS config` and `...with changed TLS config`.

✅ Passed checks (17 passed)

Check name	Status	Explanation
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Unit Tests For Go Changes	✅ Passed	The PR modifies pkg/network/render.go and a bindata YAML template, and also modifies pkg/network/render_test.go with coverage for the config-hash behavior.
Rbac Least Privilege	✅ Passed	The commit changes only one scoped YAML file, and its diff adds an annotation to kind Deployment. No Role, ClusterRole, rules, verbs, or resources RBAC rule changed.
Docs For Feature And Behavior Changes	✅ Passed	The diff fixes stale TLS configuration by hashing the existing ConfigMap into the pod template; the check explicitly passes bug fixes, so docs/ changes are not required.
Stale Project Docs And Config	✅ Passed	The PR changes only console-plugin manifests and rendering code. All in-scope docs and .coderabbit.yaml are unchanged, and no reference conflicts with the new hash behavior.
Go And Test Code Quality	✅ Passed	The diff adds contextual error wrapping; its err shadows are immediately checked. New tests use t.Setenv, with no bare t.Fatal, time.Sleep, forbidden logging, duration, IPv4-only, or concurrency is...
Stable And Deterministic Test Names	✅ Passed	The only added test title is a static t.Run string; it contains no generated values, timestamps, names, IPs, or random identifiers.
Microshift Test Compatibility	✅ Passed	The PR adds a standard Go unit test with t.Run, not a new Ginkgo e2e test; no MicroShift-incompatible APIs, namespaces, or assumptions are introduced.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR adds a standard Go unit subtest, not a Ginkgo e2e test; it renders manifests and compares hashes without any multi-node or HA assumption.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff adds only a pod-template hash annotation and hashing logic; existing preferred anti-affinity, maxUnavailable: 1, and linux selector are unchanged.
Ote Binary Stdout Contract	✅ Passed	The commit adds hashing, JSON buffering, and a YAML annotation only; it adds no stdout or suite-setup writes, and the existing render log.Printf predates the commit.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The added test is a local Go `testing.T`/`t.Run` unit test, not a Ginkgo e2e test; it performs rendering only and opens no network or external connection.
No-Weak-Crypto	✅ Passed	The PR adds only Go crypto/sha256 hashing with hex encoding; the patch contains no MD5, SHA-1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges	✅ Passed	The PR adds only a config-hash annotation and hashing logic; the deployment's existing non-root and allowPrivilegeEscalation:false settings remain unchanged, with no forbidden privilege fields added.
No-Sensitive-Data-In-Logs	✅ Passed	The diff adds no logging. It hashes the rendered ConfigMap and sets an annotation; new errors contain operation context only, while TLS data includes configuration directives, not credentials.
Description check	✅ Passed	The description clearly explains the ConfigMap hash annotation and the resulting pod rolling update.
