$ mkdir -p $HOME/.kube
$ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
$ sudo chown $(id -u):$(id -g) $HOME/.kube/config
# kubectl completion bash | sudo tee /etc/bash_completion.d/kubectl > /dev/null (kubectl bash completion)
# kubectl get node (test cluster)
# for i in `kubectl api-resources | awk '{print $1}'`; do echo "### Resource $i ###" && kubectl get $i -A; done (show all resources)
# kubectl patch <resource> <name> -n <namespace> -p '{"metadata": {"finalizers": null}}' --type merge (set resource finalized)
# helm completion bash > /etc/bash_completion.d/helm (helm bash completion)
This command (with kubectl 1.11+) will show you what resources remain in the namespace:
# kubectl api-resources --verbs=list --namespaced -o name \
| xargs -n 1 kubectl get --show-kind --ignore-not-found -n <namespace>
# kubectl port-forward service/argo-cd-argocd-server -n argocd --address 192.168.109.100 8080:443
