What are Kubernetes namespaces for?

To encrypt the traffic that moves between the pods of the cluster
To split one cluster into sections with names, quotas and permissions (Correct option)
To store the container images that belong to each team
To schedule jobs at fixed times of the day inside the cluster

To divide one cluster into logical virtual sections (e.g. dev, staging, team-a) with separate names, quotas and permissions

A namespace is a folder-like boundary inside a cluster. Two teams or environments can both have a Service called api without clashing.

You can attach resource quotas and access rules (RBAC) per namespace. Default namespaces: default, kube-system (cluster components).

Use kubectl get pods -n staging to choose one.

Namespace = logical partition of a cluster.
