Namespace (Kubernetes) - CI/CD Glossary Definition
A namespace is a virtual cluster inside a Kubernetes cluster that scopes names, RBAC, and quotas. Objects in different namespaces can share names, and most CI pipelines deploy each environment (staging, prod) into its own namespace.
Why it matters
Namespaces give a deploy job a blast-radius boundary: a misconfigured rollout into staging cannot touch prod objects.
