What is a Namespace?
In Kubernetes, Namespaces are used to organize resources. You can have multiple Namespaces in a Cluster And these Namespaces are kind of virtual Clusters of their own.
The official definition of Namespace says “In Kubernetes, namespaces provide a mechanism for isolating groups of resources within a single cluster”. Within a Kubernetes Namespace, resources must have unique names, but across different Namespaces, you can have resources with the same name. When you create a Kubernetes cluster, by default Kubernetes gives you 4 Namespaces out of the box:
- default
- kube-node-lease
- kube-public
- kube-system
