Question 3 of 90
What are Kubernetes namespaces and why are they used?
← All Kubernetes questions
Re-explain
Namespaces partition one cluster into virtual clusters, so several teams or environments can share it. Each namespace gives its group:
- Name scoping. Names must be unique only within a namespace, so
dev and prod can each have a Service called api.
- Environment separation. Dev, staging and prod objects are listed and deleted per namespace.
- Access control. A
RoleBinding grants a team permissions in one namespace only.
- Resource quotas. A
ResourceQuota caps the CPU, memory and object count a namespace can use.
Pods in different namespaces can still reach each other unless a NetworkPolicy blocks them. Node and PersistentVolume objects belong to no namespace.
kubectl create namespace development
kubectl get pods --namespace=development
