This repository spins up elastic kubernetes service (EKS) in the AWS cloud. It uses spot instances to spin up the cluster. The cluster is deployed using terraform.
The repository contains the infrastructure code for the AWS EKS cluster. The infrastructure is deployed using Terraform. The infrastructure is deployed to the AWS region specified in the terraform.tfvars file.
The infrastructure is deployed in the following order:
- VPC
- EKS cluster
- EKS node group
- EKS node group autoscaling group
- EKS node group security group
- EKS node group IAM role
- EKS node group IAM role policy
- EKS node group IAM instance profile
- Terraform 0.12.24
- AWS CLI
- AWS IAM Authenticator
- kubectl
- public ssh key located in ~/.ssh/id_rsa.pub
