Get Nodes

Fetch a list of nodes in your cluster:

kubectl get nodes

This will output something like so:

NAME                         STATUS     ROLES           AGE   VERSION
kube1.mydomain.com           Ready      control-plane   27d   v1.32.0
kube2.mydomain.com           NotReady   control-plane   27d   v1.32.0
kube3.mydomain.com           Ready      control-plane   27d   v1.32.0

Get All

kubectl get all returns a list of pods, services, daemon sets, deployments, replica sets, jobs, cronjobs, and stateful sets. These are the built-in resource types.

kubectl get all

Delete Node

Run the following command to remove a node from your cluster. Be sure to have drained it first.

kubectl delete node kube2.home.programster.org

Get Pods Running On A Particular Node

NODE="kube1.mydomain.com"
kubectl get pods --all-namespaces -o wide --field-selector spec.nodeName=$NODE
