# AWS EKS Better Practice with Terraform

## Update **frequently**(break points)

### Kubeconfig(Pre-requisite)

- awscli

- kubectx

```sh

export AWS_PROFLIE=YOUR_PROFILE

export CLUSTER_NAME=YOUR_CLUSTER_NAME

# Cleanup

# caveat: the cluster and context would be removed but the USER would NOT

k ctx -d $AWS_PROFILE@$CLUSTER_NAME

k config delete-cluster $CLUSTER_NAME

# TODO: more elegant way e.g. cli, krew?

# Set a simple context and user name,

# each with CLUSTER_NAME and AWS_PROFLIE, not the verbose arn

aws eks update-kubeconfig --name $CLUSTER_NAME --alias $AWS_PROFILE@$CLUSTER_NAME --user-alias $AWS_PROFILE

# Set a simple cluster name over the verbose arn

sed -i s%$(aws eks describe-cluster --name $CLUSTER_NAME | jq -r .cluster.arn | awk -F/ '{ print $1"/" }')%% -- $HOME/.kube/config

```

## Roadmap

Implement [EKS workshop](https://www.eksworkshop.com/)'s each part

  - [Storage](https://www.eksworkshop.com/docs/fundamentals/storage/)

    - [ ] [EBS](https://www.eksworkshop.com/docs/fundamentals/storage/ebs/)

    - [ ] [EFS](https://www.eksworkshop.com/docs/fundamentals/storage/efs/)

- [Autoscaling](https://www.eksworkshop.com/docs/autoscaling/)

  - [ ] [Karpenter](https://www.eksworkshop.com/docs/autoscaling/compute/karpenter/)

## Diagrams

### Two-steps of Provisioning

![one-two-prov](img/one-two-prov.png)

- One provisionig with Terraform

  - VPC

  - EKS cluster

  - Karpenter(AWS' things)

  - Helm

    - Karpenter

    - ArgoCD

- Two provisioning with ArgoCD

  - Karpenter things

    - AWSNodeTemplates

    - Provisioners

  - Sample applications

How to connect two steps?

- Terraform outputs should be passed Helm(ArgoCD) values.
