beautiful-nodes

This is a Terraform deployment for a high availability k3s architecture on AWS.

The k3s server nodes use a shared external RDS Postgres db and are deployed on multiple AZs.
Multiple public and private subnets are provisioned based on your settings in beautiful-nodes.tfvars.
Load balancer routes traffic to healthy server nodes.
When the k3s nodes are started, the kubeconfig and certificates are copied to a local directory on your machine. This will allow you to perform kubectl commands from your local machine.
Note the access_ip variable should only include your public IP. If this is left at 0.0.0.0/0, it will open to world

Prerequisites

Terraform
Kubectl (if you wish to control the server nodes from your local machine)
