Provision production ready EKS cluster

POKE ==> Provision Opinionated Kubernetes on EKS

Poke is infrastructure as software to provision EKS cluster in an opinianated way. Code is written in nodejs utilising pulumi framework. It is opinionated in such a way to improve security and simplicity.Consider this similar to a terraform module. This package can be used to provision eks clusters declaratively with immutability and repeatability.

Please note thi is a MVP and code quality isn’t that great. But the good thing is it works. I should probably make some code optimisations going forward. I welcome PRs to make improvements.

It has following capabilities

Has the ability to create multiple clusters with multiple worker node groups with a mix of Linux and windows nodes.
Control plane API is private
Subnets are private
Default Dashboard is disabled
Autoscalling of worker groups is enabled
Nodes in worker group have private ip addresses only
Default node group is skiped
Uses spot instances for worker nodes
Has the ability to attach existing security groups to worker nodes.
Has the ability to provision both Linux and Windows worker groups
Pre existing VPC and subnets are used
Uses bottlerocket linux distribution for enhanced security of worker nodes

Some of the config options can be set as per your requirements in pulumi.dev.yaml file. This is where Pulumi keeps config values.

Requirements

Pulumi CLI
Appropriate AWS credentials in the form of environment variables, profile, or ec2 role.
AWS CLI - This is needed to fetch kubeconfig to execute kubectl commands (optional)

How to use it

Clone this repository

git clone https://github.com/bit-cloner/poke.git

cd poke

Set AWS credentials

aws configure

Initialise Pulumi - Assuming your remote state is in AWS S3.

pulumi login s3://name-of-your-state-bucket

Select the stack you want to use- This repo has a dev stack

pulumi stack select dev

Deploy the stack

pulumi up

After you are happy with details of the plan, apply it by selecting Yes

This should create 2 clusters eks18-dev and eks19-dev as per declerations made in pulumi.dev.yaml file. You can tweak these elements to customise as per your requirements. For example if you want to add another cluster to your stack , add another code block and edit index.js file accordingly.
