Setting up AWS EKS (Hosted Kubernetes)

See https://www.terraform.io/docs/providers/aws/guides/eks-getting-started.html for full guide

Download kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin

Download the aws-iam-authenticator

wget https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/download/v0.3.0/heptio-authenticator-aws_0.3.0_linux_amd64
chmod +x heptio-authenticator-aws_0.3.0_linux_amd64
sudo mv heptio-authenticator-aws_0.3.0_linux_amd64 /usr/local/bin/heptio-authenticator-aws

Modify providers.tf

Choose your region. EKS is not available in every region, use the Region Table to check whether your region is supported: https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/

Make changes in providers.tf accordingly (region, optionally profile)

Terraform apply

terrafomr init
terraform apply

Configure kubectl

terraform output kubeconfig # save output in ~/.kube/config

Configure config-map-auth-aws

terraform output config-map-aws-auth # save output in config-map-aws-auth.yaml
kubectl apply -f config-map-aws-auth.yaml

See nodes coming up

kubectl get nodes

Destroy

Make sure all the resources created by Kubernetes are removed (LoadBalancers, Security groups), and issue:

terraform destroy
