AWS Quickstart Terraform scripts

The AWS Quickstart Terraform scripts can be used to create the needed infrastructure for a Kubernetes HA cluster. Check out the following AWS getting started walkthrough to learn more about how to use the scripts and how to provision a Kubernetes cluster using KubeOne.

Summary

Create Cluster

terraform apply

terraform output -json > tf.json

export AWS_PROFILE=default

kubeone install config.yaml --tfjson .

cp hannes-kubeconfig ~/.kube

export KUBECONFIG=~/.kube/hannes-kubeconfig

Delete Cluster

kubeone reset config.yaml --tfjson

terraform destroy
