Notes for importing managed clusters into Cluster API

WARNING: This hasn't been tested extensively outside of my environment. Your mileage may vary.

Assumptions:

  • Any security group modifications or creation that CAPA does that's not specifically flagged below are acceptable for a brief disruption when modified
  • This is valid as of CAPA 2.0.2. This may not work with new versions (e.g., the steps were different pre-2.x and it was easier to import even the VPC itself pre-2.x)

Importing CAPA Cluster (using BYO VPC):

  • Make sure AWSManagedControlPlane.spec.eksClusterName matches the EKS cluster name
  • Optionally set AWSManagedControlPlane.spec.network.securityGroupOverrides.controlplane to match the security group you have on the EKS controlplane. If you have extra security groups I haven't been able to figure out how to import those into CAPA but they stay attached to the EKS cluster and are just ignored by CAPA
  • Set the VPC information according to the BYO VPC specs https://cluster-api-aws.sigs.k8s.io/topics/bring-your-own-aws-infrastructure.html#configur
