Kubernetes API - gets Pods on specific nodes
As mentioned in the accepted answer the PR is now merged and you can get pods by node as follows:
kubectl get pods --all-namespaces -o wide --field-selector spec.nodeName=<node>
Example sorting pods by nodeName:
kubectl get pods -o wide --sort-by="{.spec.nodeName}"
Example of getting pods on nodes using label filter:
for n in $(kubectl get nodes -l your_label_key=your_label_value --no-headers | cut -d " " -f1); do kubectl get pods --all-namespaces --no-headers --field-selector spec.nodeName=${n} done
or by number of restarts
kubectl get pods --sort-by="{.status.containerStatuses[:1].restartCount}"
Example filtering by nodeName using --template flag:
$ kubectl get nodesNAME STATUS AGEip-10-0-90-30.ec2.internal Ready 2dip-10-0-90-35.ec2.internal Ready 2dip-10-0-90-50.ec2.internal Ready,SchedulingDisabled 2dip-10-0-91-60.ec2.internal Ready 2dip-10-0-91-65.ec2.internal Ready 2d$kubectl get pods --template '{{range .items}}{{if eq .spec.nodeName "ip-10-0-90-30.ec2.internal"}}{{.metadata.name}}{{"\n"}}{{end}}}{{end}}'filebeat-pezchapp-5xolenode-exporter-6kfs8prometheus-0sso-359976856-wu8zt
You also can query for all pods an a node with the following command
kubectl get pods -o wide --all-namespaces | grep <YOUR-NODE>
