AWS EKS configuration issues

Hi,

First, I would suggest that you update your question with more details about the messages coming with NodeCreationFailure to obtain better support from re:Post Community.

Second, you should go to this page: https://docs.aws.amazon.com/eks/latest/userguide/troubleshooting.html

NodeCreationFailure

Your launched instances are unable to register with your Amazon EKS cluster. Common causes 
of this failure are insufficient node IAM role permissions or lack of outbound internet access for 
the nodes. Your nodes must meet either of the following requirements:

Able to access the internet using a public IP address. The security group associated to the subnet 
the node is in must allow the communication. For more information, see Subnet requirements and 
considerations and Amazon EKS security group requirements and considerations.

Your nodes and VPC must meet the requirements in Private cluster requirements.

The text above contains hyperlinks to more details, so get to the page to obtain those hyperlinks to be able to obtain all guidance.

Best,
