kubernetes/deployment.go (1)
20-20: Consider using Info level for resource operations.Since this function is crucial for DR operations, consider using
log.Infoinstead oflog.Trace. This will provide better visibility into resource operations during critical scenarios.- log.Trace("Getting resource") + log.Info("Getting resource")kubernetes/deployment_test.go (2)
24-42: Fix inconsistent test case naming.The test case key "GetDeployment(...):" has a trailing colon which is inconsistent with typical test case naming conventions.
Consider this improvement:
testCases := map[string]testCase{ - "GetDeployment(...):": { + "should get existing deployment": { // ... }, - "GetDeployment(...): not found": { + "should handle non-existent deployment": { // ... }, }
16-42: Consider adding more test cases for better coverage.The current test cases only cover basic success and not-found scenarios. Consider adding test cases for:
- Different namespaces
- Invalid namespace names
- Invalid deployment names
- Context cancellation scenarios

1-11: LGTM! Well-organized imports and package declaration.
The imports are properly organized and include all necessary dependencies for Kubernetes client operations and logging.
13-23: Verify CoreDNS-specific usage of this function.
Since this PR is titled "feat: check CoreDNS", let's verify how this function is used in relation to CoreDNS operations.
kubernetes/deployment_test.go (2)
1-14: LGTM! Imports are well-organized and necessary.
The package name and imports are appropriate for a Kubernetes deployment test file.
53-53: Verify the GetDeployment function implementation.
The test assumes the existence of a GetDeployment function. Let's verify its implementation.
✅ Verification successful
GetDeployment function is properly implemented
The function is correctly implemented in kubernetes/deployment.go:
- Takes the required parameters: kubeClient, namespace, and name
- Uses the Kubernetes client's AppsV1 API to get the deployment
- Returns the deployment object and error as expected
- Includes appropriate logging
🏁 Scripts executed
The following scripts were executed for the analysis:

#!/bin/bash
# Search for the GetDeployment function implementation
ast-grep --pattern 'func GetDeployment($_, $_, $_) {

# Let's try a broader search for GetDeployment using ripgrep

16-23: Consider enhancing test coverage with additional test case fields.The test structure is good, but consider adding fields to test more scenarios:
- Different deployment specifications (replicas, labels, etc.)
- Various metadata annotations
- Update scenarios
Example enhancement:
type testCase struct { deployment *appsv1.Deployment expectNotFound bool + // Additional fields for better coverage + expectedReplicas *int32 + withLabels map[string]string + withAnnotations map[string]string }
43-61: Consider adding cleanup between test cases.The test execution is well-structured, but consider adding cleanup between test cases to ensure complete isolation.
for testName, testCase := range testCases { c.Logf("testing kubernetes.%v", testName) + // Clean up any existing resources + if err := kubeClient.AppsV1().Deployments(testCase.deployment.Namespace).Delete( + ctx, testCase.deployment.Name, metav1.DeleteOptions{}); err != nil { + if !apierrors.IsNotFound(err) { + c.Assert(err, IsNil, Commentf(test.ErrErrorFmt, testName)) + } + } // ... rest of the test case ... }

1-14: LGTM! Imports are well-organized and appropriate.
All necessary dependencies are properly imported for testing Kubernetes deployments.
16-61: Verify test coverage for DR volume scenario.
While the test coverage for the GetDeployment function is good, please ensure that this change adequately tests the DR volume reattachment scenario mentioned in issue longhorn/longhorn#9752.
