Bare Metal Kubernetes Cluster Setup

This repository is a step by step guide for configuring a bare metal Kubernetes cluster. This is really just an organized collection of my notes and configs, but others can use these as a starting point.

Configuration:

Configuring API High Availability

Provisioning a Bare Metal Cluster

Configuring a Bare Metal Load Balancer

Configuring an Ingress Controller with SSL

Configuring the Kubernetes Dashboard with Metrics

Configuring Network Policies

Components

1. Keepalived: VRRP Software for high-availability
2. HAProxy: Load-balancer for Kubernetes API
3. MetalLB: Provides a highly-available IP address for all external traffic entering the cluster
4. Ingress-NGINX: Ingress controller that acts as a reverse proxy, and handles SSL termination
5. cert-manager: Automates TLS certificates
6. Dashboard: Official web UI for Kubernetes clusters
7. Metrics Server: Provides resource usage data
