In this video we will look at various kubectl commands that could be used with nodes. This is just a fun exercise to play with the minikube single node cluster that we commissioned in the previous video.

1. kubectl get nodes

2. kubectl get nodes -o wide

3. kubectl get nodes -o yaml

4. kubectl get nodes -o json | less

5. kubectl get nodes -o jsonpath='{.items[*].metadata.name}'

6. kubectl get nodes -o jsonpath='{.items[*].status.addresses[?(@.type=="InternalIP")].address}'

7. kubectl get nodes -o custom-columns='NAME:.metadata.name,InternalIP:.status.addresses[?(@.type=="InternalIP")].address'

8. kubectl get nodes --field-selector=metadata.name==minikube

9. kubectl get nodes --show-labels

10. kubectl label node minikube name=cloudezee

11. kubectl get nodes --selector name=cloudezee

12. kubectl taint node minikube name=cloudezee:NoSchedule

13. kubectl get node minikube -o yaml | grep taints -A 10

14. kubectl get pods -o wide

15. kubectl run nginx-pod --image=nginx

16. kubectl get pods -o wide

17. kubectl delete pod nginx-pod

19. kubectl run nginx-pod --image=nginx --dry-run=client -o yaml > nginx-pod.yaml

20. nano nginx-pod.yaml, and add following under specs:

20. kubectl create -f nginx-pod.yaml
