Namespaces

Work with namespaces

SHELL

1kubectl get ns

2kubectl create ns staging

3kubectl get pods -n staging

4kubectl get pods -A # all namespaces

5kubectl delete ns staging # deletes everything inside it

Contexts

Switch clusters / default namespace

SHELL

1kubectl config get-contexts

2kubectl config current-context

3kubectl config use-context kind-dev

4kubectl config set-context --current --namespace=staging

5

6# merge another kubeconfig into yours

7KUBECONFIG=~/.kube/config:~/prod.yaml kubectl config view --flatten > ~/.kube/merged && mv ~/.kube/merged ~/.kube/config

Tip

Install kubectx and kubens for fast switching. Show the current context in your shell prompt (e.g. kube-ps1) so you never run a command against production by accident.
