Can you explain what is meant by namespace in the context of Kubernetes?

In Kubernetes, a namespace is a logical resource isolator within a single cluster. It allows dividing objects (pods, services, configs, etc.) between different teams or projects to avoid name conflicts and simplify management.

For example, in one cluster, you can create namespaces dev, test, and prod, each with its own pods with the same names, but they will not overlap.

Main advantages of namespaces:

• Resource isolation
• Access control (RBAC) at the namespace level
• Simplified organization and monitoring

Example of creating a namespace:

kubectl create namespace dev
kubectl get pods -n dev
