Finally AWS EKS is generally available. If you are keen to give it a go you have 2 docs to start:

• Getting Started Guide
• EKS blog

Unfortunately both have a lot of manual steps. I wanted to have an autoated way to create a 3 node EKS cluster.

Usage

It is as simple as:

source ./all.sh 
eksCreateCluster

Now your env is ready to use kubectl against eks. The KUBECONFIG env var is pointing to ~/.kube/config-eks

$ kubectl get all
NAME                 TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
service/kubernetes   ClusterIP   10.100.0.1   <none>        443/TCP   16m

To wait for nodes joining:

$ kubectl get nodes --watch

After a couple of minutes you will see all Workers as Ready:

$ kubectl get no
NAME                              STATUS    ROLES     AGE       VERSION
ip-192-168-144-225.ec2.internal   Ready     <none>    1m        v1.10.3
ip-192-168-227-12.ec2.internal    Ready     <none>    1m        v1.10.3
ip-192-168-72-48.ec2.internal     Ready     <none>    1m        v1.10.3

Configuration

You can change all paramters, most notably: instanceType, min and max worker numbers:

export EKS_NODE_TYPE=t2.small
export EKS_NODE_MIN=3
export EKS_NODE_MAX=3

eksCreateCluster

Cleanup

To delete every resources (VPC, Workers, EKS cluster)

eksCleanup

Note: the eksServiceRole and keyPair will be kept.
