ROSAKarpenterControllerPolicy

Summary

Provides permissions for the ROSA Karpenter controller to dynamically provision and manage EC2 instances for Red Hat OpenShift Service on AWS (ROSA) hosted control plane clusters. This includes EC2 fleet and instance lifecycle management, instance pricing queries, KMS operations for EBS volume encryption with customer-managed keys, and IAM instance profile management.

Permissions imported from the AWS Managed Policy Reference Guide; other sections pending editorial review.

Control-plane actions (33)

By access level: 13 List, 1 Permissions management, 3 Read, 2 Tagging, 14 Write.

Data-plane actions (0)

By access level: none.

This policy grants no actions in this plane.

Excluded and conditional actions

No patterns are excluded by NotAction or Deny statements.

Resource scope and attachment

Resource scope across granted actions: mixed.

Can be attached: Yes, to users, groups and roles.

Why this tier

• Grants 17 write, tagging or permissions-management actions, short of full control of any service.
• Grants iam:PassRole, but only for scoped roles or under conditions (for example iam:PassedToService).
