What:
We need to add a second node group on EKS to be used exclusively by prometheus due to the application using up a lot/most of the resources of a given node and causing issues for other pods on the node.

Why:
We do this on the current KOPS cluster and found it resolves the above issues
https://github.com/ministryofjustice/cloud-platform-infrastructure/blob/68278816d7192b545416e70bbf48d5373bcdf45a/terraform/aws-accounts/cloud-platform-aws/vpc/kops/main.tf#L78

Definition of Done:

  • 2nd node group created, running the prometheus instance(s)
