📝 Walkthrough

Walkthrough

The operator now reads proxy values from the cluster Proxy resource through the Kubernetes API. Startup and node configuration handle lookup errors. The ConfigMap controller watches the cluster Proxy and regenerates the Windows services manifest when proxy settings change. RBAC grants the required Proxy permissions. End-to-end tests validate ConfigMap, system, and service environment variables during sequential proxy updates.

Pre-merge checks failed

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

❌ Failed checks (1 error, 3 warnings)

Check name	Status	Explanation	Resolution
No-Sensitive-Data-In-Logs	❌ Error	New e2e failure messages print proxy maps and environment values; the repository's proxy setup embeds PASSWORD in HTTP_PROXY/HTTPS_PROXY URLs.	Redact proxy credentials and sensitive values in test errors. Report variable names and presence, or sanitize proxy URLs before formatting diagnostics.
Go Best Practices & Build Tags	⚠️ Warning	The PR adds raw error propagation in test/e2e/proxy_test.go (lines 437 and 447) instead of adding fmt.Errorf context with %w.	Wrap the getWMCOVersion and getCurrentServicesConfigMapName errors with operation context using fmt.Errorf("...: %w", err).
Security: Secrets, Ssh & Csr	⚠️ Warning	Added e2e errors print Proxy status-derived values with %v/%q in waitForConfigMapProxyVars and checkNodeProxyVars; proxy URLs can contain authentication credentials.	Redact proxy values from diagnostics. Report only variable names, presence, and counts, or use a credential-safe proxy URL formatter.
Test Structure And Quality	⚠️ Warning	The new removal checks call checkNodeProxyVars, which creates Kubernetes Jobs through runPowerShellSSHJob/runJob, but no cleanup deletes those Jobs.	Delete each diagnostic Job after log collection, using defer or t.Cleanup, and retain bounded job waits and contextual assertion messages.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Docstring Coverage	✅ Passed	Docstring coverage is 80.00% which is sufficient. The required threshold is 80.00%.
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.
Kubernetes Controller Patterns	✅ Passed	The diff adds a cluster-only Proxy watch, returns reconciliation errors for automatic requeue, and preserves idempotent ConfigMap validation/recreation. Status, finalizers, and owner references are...
Windows Service Management	✅ Passed	Diff changes proxy inputs and ConfigMap reconciliation only; service definitions, priority/dependency validation, cleanup, descriptions, SCM calls, and reboot comments are unchanged.
Platform-Specific Requirements	✅ Passed	PR changes proxy reconciliation and an image digest; AWS, Azure, GCP, and vSphere service logic is unchanged, and existing docs cover the listed limits, EC2LaunchV2, and platform requirements.
Stable And Deterministic Test Names	✅ Passed	The PR adds only static titles: “services ConfigMap” and fixed NO_PROXY/HTTPS_PROXY/HTTP_PROXY table values; dynamic node titles predate the PR.
Microshift Test Compatibility	✅ Passed	The changed e2e file uses Go testing.T and t.Run; the diff adds no Ginkgo It, Describe, Context, or When tests, so this check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	Added proxy checks use Go t.Run subtests and iterate over existing Windows nodes; the diff adds no multi-node count, scheduling, distinct-host, failover, or topology assumption.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff adds Proxy RBAC/API watches and proxy reconciliation only; it introduces no affinity, spread, replica, PDB, node, taint, or toleration scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The PR changes no OTE source or suite setup and adds no stdout writes; root test/e2e remains outside the nested OTE module, while the added operator log is not an OTE binary.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The PR adds Go `testing` subtests, not Ginkgo tests. Added lines contain no IPv4 assumptions or external connectivity; existing public URLs are unchanged.
No-Weak-Crypto	✅ Passed	The PR diff adds proxy API access, reconciliation, and tests only; it introduces no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges	✅ Passed	The PR adds only Proxy RBAC and proxy reconciliation logic. The diff adds no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root settings.
Title check	✅ Passed	The title clearly identifies reconciliation of proxy variables from the cluster Proxy resource, which is the primary change.

WMCO copied the cluster-wide egress proxy variables into the WICD windows-services ConfigMap from the operator container's own environment and cached them in a package global that never refreshed. When a proxy field was removed from the cluster Proxy spec, WMCO's view stayed stale, the regenerated manifest still matched the ConfigMap, and the removed key lingered in data.environmentVars forever. Read the proxy values from the cluster Proxy object's status instead, and watch that object so the ConfigMap is regenerated when it changes. This makes the Proxy object the source of truth: removing a field now removes exactly that key while leaving the others intact.

The proxy e2e coverage only checked env vars on the nodes, so it could not catch stale proxy keys left behind in the WICD windows-services ConfigMap after a field was removed from the cluster Proxy. Assert the ConfigMap's environmentVars for the initial state and after staged per-field removal (NO_PROXY, HTTPS_PROXY, HTTP_PROXY), verifying only the removed key drops and the rest remain. Add helpers to read the proxy vars from the ConfigMap and wait for them to converge. The cluster Proxy status is updated asynchronously from the spec patch, so wait for the status to change before deriving the expected variables to avoid comparing the ConfigMap against a stale expectation.
