Out of the box, there is a Namespace called ‘default‘ in a Kubernetes cluster.
By default, the kubectl command interacts with this ‘default‘ Namespace, but it can be changed to any other Namespace.
In this note i will show how to set the default Namespace in Kubernetes.

Set Default Namespace in Kubernetes
To get the list of all Namespaces in a Kubernetes cluster, run one of the commands below:
$ kubectl get namespaces
- or -
$ kubectl get ns
- sample output -
NAME STATUS AGE
default Active 1d
kube-node-lease Active 1d
kube-public Active 1d
kube-system Active 1d
To find out the current Namespace name:
$ kubectl config view --minify --output 'jsonpath={..namespace}'; echo
- sample output -
default
To change the Namespace (set the default namespace for the current context):
$ kubectl config set-context --current --namespace=<NAME>
The command above sets the default Namespace for the current context, so all the kubectl commands in this context, by default, will be executed in the defined Namespace.
