Question

Mention different kinds of Namespaces in Kubernetes.

Answer 1

The namespaces are of three kinds. They are:

1. Default: The default namespace that when the cluster comes out of the box with no other namespaces
2. Kube-system: The namespace for objects created by Kubernetes. 
3. Kune-public: The namespace that can create automatically and is visible and readable publicly throughout the whole cluster. The public aspect of this namespace is only convenient and reserved for cluster usage.
