I couldn't find useful information from:
gcloud container clusters describe CLUSTER_NAME
or from
gcloud container node-pools describe POOL_NAME --cluster CLUSTER_NAME
It is easy to scale up/down using gcloud
tool though:
gcloud container clusters resize [CLUSTER_NAME] --node-pool [POOL_NAME] \
--size [SIZE]
But how can I know beforehand what is the size of my node-pool?
You should use the following command:
gcloud container clusters describe <cluster name> --zone <zone-cluster>
Check for the field currentNodeCount
