• Before installing Autoscaler make sure you set k8s environment and update-kubeconfig:

  # export KUBE_CONFIG_PATH=~/.kube/config
  # aws eks --region eu-central-1 update-kubeconfig --name 'nt-eks-xxxx'
  

• VPC name and VPC CIDR can be set editing: _variables.tf
• Edit backend.s3 in _variables.tf to determine where state will be stored
