Found this issue - https://github.com/aws/karpenter/issues/2729

Can you check if it works with EKS v1.25

Thanks a lot for your help!

Added version -

karpenter = Karpenter(self, "karpenter", cluster=cluster, version='0.27.1')

Still fails - Error: public.ecr.aws/karpenter/karpenter:0.27.1: not found

[badaldavdatcpl]

Tried with -

karpenter = Karpenter(self, "karpenter", cluster=cluster, version='v0.27.1') ## version is mandatory and v before version (0.27.1) is mandatory example vX.YY.Z

It works.

version is mandatory parameter for karpenter it seems and v before version (0.27.1) is mandatory example vX.YY.Z

A validation check to fail on not adding version would help here.

Closing the issue.

Improvements -

1. Examples for python and TS with full code with eks cluster will help
2. Validation on adding version as mandatory with 'v' added to it and added in documentation will help
