Kubernetes/GCP GKE Aspects

Show nodes in each node pool:

gcloud container clusters list

export CLUSTERNAME=mycluster
export LOCATION=us-central1

for i in `gcloud container node-pools list --cluster ${CLUSTERNAME} --region ${LOCATION} | grep -v NAME | awk '{print $1}'`
 do
 echo $i ;
 kubectl get node -l cloud.google.com/gke-nodepool=$i
 done

cordon one node pool:

for i in `kns get no -l cloud.google.com/gke-nodepool=production-gcp-env-blue -o name`
do
 echo $i
 #kubectl node cordon $i
done
