Deploy AWS EKS stack using Terraform and Bash

In this project, we're going to deploy AWS EKS, 2xEC2 instances (It will be the K8S workers), helm/tiller, Kubernetes Dashboard and create two users (1x admin and 1x user just for the default namespace).

How to use

You can run the initial Bash script, it will look for dependencies (terraform, helm, etc) and you can choose between Deploy and Destroy.

Example:

./deploy_eks_stack.sh
2019-07-14 19:07:24 Checking for dependencies
What action you want to execute?
1) Deploy
2) Destroy
Default: Deploy
-> 1

or

./deploy_eks_stack.sh Deploy
2019-07-14 20:31:40 Checking for dependencies
2019-07-14 20:31:40 Starting to deploy the AWS EKS stack

Getting my Token

By default, this automation will create two users. One is mlozano-admin (Cluster admin) and another mlozano-user (For default namespace).

To get the token, you can run this command.

my_user=mlozano
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | awk '/'"${my_user}"'/ { rc = 1; print $1 }; END { exit !rc }' || echo "${my_user}")

Accessing K8s Dashboard

The dashboard is configured to be "public" (Allowed just for few external IPs) and with HTTP over TLS.

Run this command to get the external address.

kubectl -n kube-system get service

The output will be something like this

NAME              TYPE           CLUSTER-IP      EXTERNAL-IP                                       PORT(S)          AGE
