Editing AWS Elastic Kubernetes Service (EKS)

[[AWS]] Elastic [[Kubernetes]] Service ([[EKS]]) is a managed [[Kubernetes]] solution for running [[containers]] available in AWS cloud platform since June 2018 <ref>https://en.wikiversity.org/wiki/DevOps/Kubernetes/EKS</ref>. EKS can be managed using [[Jenkins X]] software <ref>https://aws.amazon.com/blogs/opensource/continuous-delivery-eks-jenkins-x/</ref>. Other AWS services for running containers are [[ECS]] or [[Fargate]].

By default EKS provides 3 [[master node]]s and 3 <code>[[etcd]]</code> nodes, but are invisible to you and Amazon is responsible of AutoScaling them when needed.

== Creation your first EKS Cluster <ref>https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html</ref> ==
:0) Prerequisites: <code>[[kubectl]]</code> and <code>aws-iam-authenticator</code> (a tool to authenticate to Kubernetes using AWS IAM credentials)<ref>https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html</ref>
:: On macOS: <code>brew install aws-iam-authenticator</code> and <code>brew install kubernetes-cli</code> 
:1) Create a new service role
:2) Create a new VPC for you new EKS Cluster using this [[CloudFormation]] template from AWS: https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html
:3) Create EKS Cluster from AWS Webconsole, user used for creating EKS Cluster will be the initial administrator.
:4) Create Worker Nodes using AWS Cloudformation template https://github.com/awslabs/amazon-eks-ami/blob/master/amazon-eks-nodegroup.yaml
:5) Install Kubernetes dashboard<ref>https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/</ref>

== Costs ==
[[EKS]] is not included in [[AWS Free Tier]], usually running an EKS cluster is more expensive than [[ECS]] for small deployments. [[Google Kubernetes Engine (GKE)]] offers free trial Kubernetes service.
