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.
Scaling down can evict pods. Make sure production workloads have enough replicas and disruption budgets before reducing worker count.
