Overview

In this blog post I will demonstrate how to check the current namespace for your current K8S context and how to switch to different one.

Solution

What is my current K8S namespace ?

kubectl config view --minify --output 'jsonpath={..namespace}'; echo

Output:

default

kubectl config get-contexts

Output:

CURRENT   NAME               CLUSTER            AUTHINFO                                           NAMESPACE
          dev-k8s            dev-k8s            clusterUser_dev-k8s                                apps
*         minikube           minikube           minikube                                           default

Switch to different K8S namespace

kubectl config set-context --current --namespace=tracing

Output:

Context "minikube" modified.

Double check the current context

kubectl config view --minify --output 'jsonpath={..namespace}'; echo

Output:

tracing

kubectl config get-contexts

Output:

CURRENT   NAME               CLUSTER            AUTHINFO                                           NAMESPACE
          dev-k8s            dev-k8s            clusterUser_dev-k8s                                apps
*         minikube           minikube           minikube                                           tracing
