Resize a cluster when workloads need more capacity or when you want to reduce cost after a load test.

​
When to resize

Resize when:
  • Pods are pending because there is not enough CPU or memory.
  • Nodes stay near resource limits.
  • You need extra capacity before a launch.
  • Development workloads no longer need as many workers.

​
Change worker count

1

Open the cluster

Go to Kubernetes Clusters and open the target cluster.
2

Open node pools

Choose the node pool you want to resize.
3

Update worker count

Increase or decrease the worker count.
4

Watch node state

Use kubectl get nodes to verify the cluster sees the desired nodes.
kubectl get nodes
kubectl get pods --all-namespaces
Scaling down can evict pods. Make sure production workloads have enough replicas and disruption budgets before reducing worker count.
