## Orchestration of a 2 Controller 3 Nodes Kubernetes Cluster ### For High Availability and a Reverse Proxy
This repository contains the code for orchestrating a Kubernetes cluster with two controllers and three nodes, all running on LXD containers. It also sets up a reverse proxy using Nginx to expose the Kubernetes API server to the outside world.
To get started, first install LXD by running:
sudo snap install lxdThen, create and initialize the LXD instance with:
sudo lxd initNext, install Terraform by running:
sudo snap install terraformYou'll also need to add the Terraform LXD provider plugin by running:
terraform init -plugin-dir=$HOME/.terraform.d/plugins/In the main.tf file, you'll need to add the LXD provider configuration:
provider "lxd" {
# Configuration options
}Before you start Terraform, generate a key for your SSH connection that will be used by Terraform:
ssh-keygen -t rsa -b 4096 -C <your_email>This will save the id_rsa and id_rsa.pub files to ~/.ssh/. Make sure to replace <your_email> with your email address.
Note that there are two types of images available for LXD containers: cloud-init and standard Ubuntu images. The cloud-init images are more lightweight and provide a faster startup, but require cloud-init to be installed and configured. For this reason, this repository uses standard Ubuntu images.
Once you've set up LXD and Terraform, you can run Terraform by executing:
terraform applyThis will create the LXD containers and set up the Kubernetes cluster. You'll be prompted to confirm that you want to apply the changes, so enter yes when prompted.
Note that this repository is a work in progress and may be unstable at this time. Contributions are welcome.
