No VPC

Use this stripped down, minimal IAM Policy if you have pre-existing AWS resources that you need to use for the Amazon EKS Cluster. With this policy example, the customer is expected to create and provide references to the following:

  • VPCs,
  • Subnets,
  • Route Table,
  • Internet Gateway and
  • NatGateway
