Small test Kubernetes environment built on AWS EKS using Terraform

aws-eks-k8s-terraform

• Small test Kubernetes environment built on AWS EKS using Terraform

Prereqs :

• Have an AWS account with your access and secret key ready and exported to local env variables

• e.g. export AWS_ACCESS_KEY_ID="$myID" && export AWS_SECRET_ACCESS_KEY="$myKEY"

• Download + install terraform

• • https://www.terraform.io/downloads.html
• • https://www.terraform.io/intro/getting-started/install.html

• Download + install kubectl

• • https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl

• Download + install heptio-authenticator-aws

• • https://github.com/kubernetes-sigs/aws-iam-authenticator
• • https://aws.amazon.com/blogs/opensource/deploying-heptio-authenticator-kops/
• • https://docs.aws.amazon.com/eks/latest/userguide/configure-kubectl.html

Steps :

• sudo su

• clone repo

• cd .. cluster

• terraform init

• terraform plan

• terraform apply

Now the cluster will build. This will take approx 10 minutes.

• mkdir ~/.kube/

• touch ~/.kube/config

• terraform output kubeconfig > ~/.kube/config

• kubectl get pods

If everything is installed and setup correctly you should ge the message 'No resources found.'

• terraform output config-map-aws-auth > aws-auth.yaml

• kubectl apply -f aws-auth.yaml

• kubectl get nodes

• cd ../kubernetes/

• terraform init

• terraform plan

• terraform apply

• kubectl get service -n demo-service -o wide

• kubectl get pods -n demo-service

• kubectl get service -n demo-service

To verify

• curl http://$EXTERNAL-IP(ELB provided in the get service output):8080

Notes :

There is currently no free tier for EKS. Current usage rates are $0.20 per hour.

Next will add steps to setup monitoring (access kube dashboard + grafana graphs for metrics)
