- Detect MP vs MD per node (node_image absence → MachinePool) - Generate AWSManagedMachinePool manifests for MP nodes - Add autoscaler RBAC for MachinePool resources - Add validation for EKS managed node group constraints - Update cluster struct to carry MP node kind info Install and MD lifecycle verified OK. MP scale/delete fix pending. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…y doc aws-load-balancer-controller v2.14.x calls DescribeListenerAttributes during NLB reconciliation. The IRSA policy reference in the installation guide was missing this action, causing AccessDenied errors in controller logs. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add CAPALaunchTemplates and CAPAAutoScalingGroups statements required for the deployment user when managing EKS MachinePools (managed node groups). Also add iam:UntagRole alongside the existing iam:TagRole. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…onfig for MachinePools - Add MPRoleName field to AWSCP struct to pass pre-existing IAM role to AWSManagedMachinePools - Add managedMachinePool block to AWSIAMConfiguration: creates eks-nodegroup role with AmazonEBSCSIDriverPolicy when create_iam: true - Add .claude/ to .gitignore
Adds a new script to assist migration of existing EKS clusters from MachineDeployments to MachinePools. The script: - Validates prerequisites (provider, CAPA >= v2.9.2, CO >= 0.6.1, status.ready) - Patches CAPA feature gates (MachinePool=true, EKSAllowAddRoles=true) idempotently - Updates cluster-operator to the target version - Provides a --check-ready assistant mode that validates MP capacity and prints drain commands for the equivalent MD worker (client executes manually)
Default is now TARGET_CLUSTER_OPERATOR_VERSION (0.9.0-PR907-SNAPSHOT) so clients can run the migration script without specifying the version manually.
Before running preparation mode, the script now prints a reminder to verify that the cluster-operator image and Helm chart are accessible in the cluster's configured registry and Helm repository.

PLT-3962 Add MachinePool support for EKS managed node groups
Description
Adds native support for
AWSManagedMachinePool(EKS managed node groups / MachinePools) in cluster-operator, while maintaining full backwards compatibility withMachineDeployment-based worker nodes.Detection logic (field-based, implicit):
node_imagepresent →MachineDeployment+AWSMachineTemplate+EKSConfigTemplateami_typepresent, or no image field →MachinePool+AWSManagedMachinePool(default:BOTTLEROCKET_x86_64)Type of Change
