Want to rotate out node group in EKS

I want to replace a node group entirely with fresh nodes in an EKS node group.

Whats is the difference between

eksctl scale nodegroup --cluster=$CLUSTER_NAME --nodes=0

And draining/deleting nodegroup, then provisioning via Terraform?

To replace an entire node group in an EKS cluster, you can either use the eksctl command or manually drain and delete the node group and provision a new one with Terraform.

eksctl scale nodegroup --cluster=my-cluster --nodes=0

This command will drain and delete all nodes in the node group, leaving the node group empty. You can then use the eksctl create nodegroup command to provision a new node group with the desired configuration.

The difference between draining and deleting a node group is that :

  • Draining a node group will gracefully terminate the nodes in the group, while deleting a node group will immediately terminate the nodes.

  • Draining a node group is typically used when you want to replace the node group with a new one, while deleting a node group is usually used when you want to completely remove the node group from the EKS cluster
