Getting the existing namespaces

The default Namespace

The kube-public Namespace

The kube-system Namespace

Try it yourself

Now that we know that our cluster has multiple Namespaces, let’s explore them a bit.

Getting the existing namespaces

We can list all the Namespaces through the kubectl get namespaces command. As with the most of the other Kubernetes objects and resources, we can also use a shortcut ns instead of the full name.

kubectl get ns

Get Namespaces in cluster

The output is as follows.

12345

NAME STATUS AGE

default Active 23m

kube-node-lease Active 23m

kube-public Active 23m

kube-system Active 23m

Output of 'kubectl get ns'

We can see that three Namespaces were set up automatically when we created the cluster.
