kubectl config use-context geralexgr-aks
Get k8s cluster context:
kubectl config view
Create a deployment:
kubectl create deployment new-app --image=hello-world:latest
Delete a deployment:
kubectl delete deployment nginx -n nginx
Describe a service:
Kubectl describe service/myservice
Get logs for pod:
Kubectl logs pod-123
Get cluster namespaces:
kubectl get namespace
Set active namespace:
kubectl config set-context --current --namespace nginx
Delete a pod:
