README

This is a github repo to deploy a Kubernetes cluster on AWS (EKS) with terraform, and to add an RShiny app with Polished Authentication.

Polished Authentication

Go through the quickstart guide to sign up and grab your secret and app name.

Deploy the Kubernetes Cluster

Grab the code!

git clone https://github.com/jerowe/rshiny-with-polished-tech-eks

EKS Cluster Code

The recipe for the EKS cluster mainly comes from the Terraform AWS EKS Module examples and is in auto-deployment/eks.

If you've never used terraform before its a very handy tool for deploying infrastructure! It's also not to bad to learn, and since they have so many prepackaged recipes you don't need to configure much on your own.

Docker Image

I've built a minimal docker image that just logs you in with polished. It doesn't do anything else! The code is all in rshiny-app-polished-auth.

Update the AWS Region

The region is set as us-east-1. If you need to change it take a look at auto-deployment/eks/variables.tf and auto-deployment/terraform-state/main.tf.

Update the credentials

Make sure to update your polished API credentials in auto-deployment/eks/variables.tf.

# auto-deployment/eks/variables.tf
# CHANGE THESE!

...

# Then make sure to add your user to the app!
variable "POLISHED_APP_NAME" {
  default = "my_first_shiny_app"
}

# Grab this from the polished.tech Dashboard -> Account -> Secret
variable "POLISHED_API_KEY" {
  default = "XXXXXXXXXXXXXXXXXX"
}

Clean up

If you'd like to get rid of your kubernetes cluster just

cd auto-deployment/terraform-state
terraform init; terraform refresh; terraform destroy -auto-approve
cd ../eks
terraform init; terraform refresh; terraform destroy -auto-approve

If anything times out and gets clobbered head on over to the AWS Console. First go to EC2 -> AutoScaling -> Autoscaling Groups and delete it.

It's this url, except with your region - https://console.aws.amazon.com/ec2/autoscaling/home?region=AWS_REGION#AutoScalingGroups:view=details

Then you can either try the destroy command again, or just destroy from the AWS EKS console.

If you're really having issues grab the script from AWS support, make some tea and delete the resources one by one.
