Google Kubernetes Engine Node Pools

In Google Kubernetes Engine, Nodes are Google Complete Engine (Virtual Machiens). Pods run inside Nodes. A Kubernetes cluster can contain multiple node pools. A node pool contain multiple nodes of same instance type.

To create a Node Pool in Google Kubernetes Engine, run

gcloud container node-pools create POOL_NAME \
  --cluster=CLUSER_NAME \
  --machine-type=e2-standard-2 \
  --num-nodes=1 \
  --zone=ZONE_NAME

To delete a node pool, run

gcloud container node-pools delete POOL_NAME --cluster CLUSER_NAME --zone ZONE_NAME

To resize a node pool, run

gcloud container clusters resize CLUSER_NAME --node-pool POOL_NAME \
    --num-nodes 3 --zone ZONE_NAME
