Infrastructure

The infrastructure of the project is rather simple but it is worth splitting it in two distinct diagrams:

  • Physical: It refers to the real infrastructure that is deployed. This includes local IP addresses for each machine, router configuration, DHCP configuration and any other configuration or device that refers to physical/real devices.
  • Logical: This mainly refers to the configuration that Cloudflare uses. The cluster is exposed via Cloudflare Tunnels and the Cloudflared client is running in each machine. In this context each node has another IP that is different from the one used by physical devices and is the one Cloudflare uses to correctly route requests.

Although the configuration for public endpoints is set up. Most of the endpoints exposed via Cloudflare are protected with Cloudflare Access.
