I have 3 nodes, running all kinds of pods. I would like to have a list of nodes and pods, for an example:
NODE1 POD1 NODE1 POD2 NODE2 POD3 NODE3 POD4 How can this please be achieved?
Thanks.

You can do that with custom columns:
kubectl get pod -o=custom-columns=NAME:.metadata.name,STATUS:.status.phase,NODE:.spec.nodeName --all-namespaces or just:
kubectl get pod -o=custom-columns=NODE:.spec.nodeName,NAME:.metadata.name --all-namespaces 5kubectl has a simple yet useful extended output format that you can use like
kubectl get pod -o wide so while custom formats provided in other answers are good, this might be a handy shortcut.
3You can use kubectl get pods --all-namespaces to list all the pods from all namespaces and kubectl get nodes for listing all nodes.
The following command does more or less what you wanted. However, it's more of a jq trick than kubectl trick:
kubectl get pod --all-namespaces -o json | jq '.items[] | .spec.nodeName + " " + .status.podIP'
Not exactly as you wanted cause it describe much more, but you can use
kubectl describe nodes
it will expose each pod per node in the cluster with the following info
1Namespace | Name | CPU Requests | CPU Limits | Memory Requests | Memory Limits
This gets you: "nodeName namespace pod" across the cluster:
kubectl get pods --all-namespaces --output 'jsonpath={range .items[*]}{.spec.nodeName}{" "}{.metadata.namespace}{" "}{.metadata.name}{"\n"}{end}'
