Create AKS cluster

• Master version >= 1.12.x (tested version: 1.12.8)
• One B4ms node

• AWS CLI (version >= 1.16.156)

Create EKS cluster on AWS

• version >= 1.13 (tested version: 1.13)
• One m5.2xlarge node
• Sample script using eksctl to create such a cluster

eksctl create cluster --version=1.13 --name=keptn-cluster --node-type=m5.xlarge --nodes=1 --region=eu-west-3

In our testing we learned that the default CoreDNS that comes with certain EKS versions has a bug. In order to solve that issue we can use eksctl to update the CoreDNS service like this:

eksctl utils update-coredns --name=keptn-cluster --region=eu-west-3 --approve
