Kubernetes: list all pods and its nodes

Solution 1:

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

Solution 2:

kubectl 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.

Solution 3:

You can use kubectl get pods --all-namespaces to list all the pods from all namespaces and kubectl get nodes for listing all nodes.

Solution 4:

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'

Solution 5:

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

Namespace | Name | CPU Requests | CPU Limits | Memory Requests | Memory Limits
