How namespaces impact your resources and services

Previously, we learned what namespaces are and we will continue to discover them. In this section, we'll learn how to create, update, and delete namespaces, as well as the impacts that namespaces have on services and Pods.

We will also learn how to create ConfigMaps and Pods by specifying a custom namespace so that we don't rely on the default one.

Listing namespaces inside your cluster

We saw this in the previous section but here is how to list the namespaces that have been created in your Kubernetes cluster:

$ kubectl get namespaces #kubectl get ns works too
NAME              STATUS   AGE
default           Active   5m31s
kube-public       Active   5m33s
kube-system       Active...
