Knowledge Base & Operational DocumentationHow to Troubleshoot a Kubernetes Application That Fails After a Namespace Rename
A namespace change alters service discovery names, policies, secrets, role bindings, and resource quotas. Moving a workload can leave references pointing to the old namespace.
What to check
Search configuration and manifests for old namespace references, inspect service names, NetworkPolicies, RBAC, secrets, ingress, and monitoring labels. Compare events before and after the move.
Recommended next step
Update references through a staged migration and verify access and discovery from each dependent workload. Keep the old namespace until traffic and scheduled jobs have moved.
