246-248: Enhance error messages for authentication failuresThe error message "error creating Kubernetes client" could be more specific when authentication fails. Consider preserving the underlying error details, especially for auth-related failures.
- return nil, fmt.Errorf("error creating Kubernetes client: %s", err) + return nil, fmt.Errorf("error creating Kubernetes client (check your authentication configuration): %w", err)
Line range hint
246-262: Consider implementing proper cleanup in error casesThe port forwarding setup should be cleaned up if subsequent operations fail. Consider using defer or ensuring proper cleanup.
clientset, err := kubernetes.NewForConfig(clientConfig) if err != nil { return nil, fmt.Errorf("error creating Kubernetes client: %s", err) } + var cleanup func() tlsConfig, localPort, err := setupPortForwarding(config, clientset) if err != nil { + if cleanup != nil { + cleanup() + } return nil, fmt.Errorf("failed to setup port forwarding: %s", err) } etcdConfig := clientv3.Config{ Endpoints: []string{fmt.Sprintf("localhost:%d", localPort)}, DialTimeout: 5 * time.Second, }

492-494: Standardize error wrapping across the codebaseError wrapping with
%wis used inconsistently. Some errors use%wwhile others use%s. Consider standardizing to use%wfor better error context preservation.- return nil, fmt.Errorf("failed to get pod: %w", err) + return nil, fmt.Errorf("failed to get pod %s in namespace %s: %w", config.PodName, config.Namespace, err) - return nil, fmt.Errorf("error building kubeconfig: %w", err) + return nil, fmt.Errorf("error building kubeconfig from %s: %w", config.Kubeconfig, err) - return nil, fmt.Errorf("failed to create round tripper: %w", err) + return nil, fmt.Errorf("failed to create round tripper for port forwarding: %w", err)Also applies to: 497-499, 502-504

23-23: LGTM: Import addresses OIDC authentication support
The addition of the auth providers import correctly enables OIDC authentication support, addressing the PR objective.
23-23: Verify OIDC authentication in different environments
The OIDC authentication support has been added correctly. Please verify:
- Authentication works with different OIDC providers
- Backward compatibility with other auth methods is maintained
- Error messages are helpful when OIDC configuration is incorrect
Also applies to: 246-248
✅ Verification successful
Let me gather more information about the auth implementation to make a more informed decision.
Based on the gathered information, I can now provide the final response:
OIDC auth support is correctly implemented via client-go auth plugins
The implementation is verified to be correct because:
- The import
k8s.io/client-go/plugin/pkg/client/authis used consistently in bothcmd/kubectl-etcd/main.goandcmd/manager/main.go - This package automatically handles all Kubernetes client auth plugins including OIDC, Azure, GCP
- Auth configuration is properly set up in the project with necessary RBAC and proxy configurations
- No manual verification is needed as this is a standard client-go authentication implementation

Subj. Without such import, there is auth error:
