Infrastructure Overview

This document provides an overview of our infrastructure.

1. Hosting Provider​

We host our infrastructure at Hetzner.

2. Hetzner Cloud Access​

To access the Hetzner Cloud console, navigate to https://console.hetzner.cloud/ and log in with your credentials. Server access is primarily via SSH using authorized keys.

3. Servers​

We have 5 dedicated servers with the following roles:

  • Coolify Server: 1 server running Coolify (188.245.90.124).
  • Nomad Agent: 1 server acting as a Nomad agent (138.199.222.109).
  • Nomad Clients: 2 servers acting as Nomad clients (91.99.17.219, 91.99.60.214).

5. DNS Provider​

We use Cloudflare for our DNS management.

6. Network Topology​

Our Hetzner environment is set up with appropriate networking configurations for server communication and service accessibility.

7. Deployment Process​

Applications are deployed via Coolify, leveraging Nomad for orchestration.

8. Access Management​

Access to our servers and services is managed through secure SSH keys, appropriate access controls, and 1Password for secure credential management.

9. HashiCorp Stack​

We leverage the HashiCorp stack for various infrastructure needs:

  • Nomad: For container orchestration (as mentioned in Core Services).
  • Consul: For service discovery and configuration.
