EKS Infrastructure for Demo

• eksctl script (one-liner) taken from the docs

• Terraform code based on the Terraform Provider example

• Cloudformation code based on AWS Quick Start

Getting Started

There are three ways presented in this repo that will help you to get a cluster up and running:

• eksctl - great for getting started quickly, will also generate Cloudformation templates
• Cloudformation - a good way to present a menu to end users
• Terraform - good for when you're managing more than just AWS resources

eksctl

Run the eksctl script:

./eksctl/script.sh

Cloudformation

Visit the Cloudformation site and upload the cloudformation/amazon-eks-template.yaml file in order to walk through the form. https://console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/create/template

You can also click the Launh Stack button below to load a snapshot of the template and get started!

Note: if you use ekctl to create a cluster and want to create more, grab the two files in the cloudfomation bucket here: https://s3.console.aws.amazon.com/s3/home?region=us-east-1# (look for bucket that starts with cf-templates)

Terraform

Ensure you have your AWS env vars setup.

Run cd terraform && terraform init

Then run terraform apply:

terraform apply -var='cluster-name=terraform-eks-demo'

Retrieve the kubeconfig with:

aws eks --region us-east-1 update-kubeconfig --name terraform-eks-demo

Check out the cluster:

kubectl get pods -A

You should see something similar to:

NAMESPACE     NAME                       READY   STATUS    RESTARTS   AGE
kube-system   aws-node-v9hkw             1/1     Running   0          3m4s
kube-system   coredns-75b44cb5b4-7bqnj   1/1     Running   0          6m45s
kube-system   coredns-75b44cb5b4-8j78j   1/1     Running   0          6m45s
kube-system   kube-proxy-tlmbv           1/1     Running   0          3m4s

Datadog Install

Ensure Datadog Keys Are Exported

Operator Installation

As the operator handles all installs, the instructions are as follows:

bash ./operator/operator_deploy.sh

Helm Instructions
