# pez-infra
|
|
|
|
Infrastructure-as-code monorepo for managing my homelab and cloud server fleet. It contains everything needed to rebuild, configure, and maintain the entire infrastructure from scratch — including server provisioning, service deployment, DNS, monitoring, and secrets management.
|
|
|
|
## What's in this repo
|
|
|
|
- **Ansible** — Playbooks, roles, and inventory for configuring servers, deploying Docker-based services, and managing dotfiles
|
|
- **Terraform** — OpenTofu/Terraform configs for cloud resources (Cloudflare DNS, Hetzner servers)
|
|
- **Services** — Docker Compose definitions and config files for each self-hosted service
|
|
- **Documentation** — Architecture decisions, networking topology, and operational guides
|
|
|
|
## Architecture Overview

```
|
|
|
|
Traffic enters via Cloudflare DNS, hits a Caddy reverse proxy on a Hetzner cloud instance, and is forwarded to backend services running on various hosts connected over a Tailscale mesh network. Authentication is handled by Authelia with an LLDAP backend.

|
## Getting Started
|
|
|
|
### Prerequisites
|
|
|
|
- SSH access to hosts via Tailscale
|
|
- `ansible` for configuration management
|
|
- `tofu` (OpenTofu) or `terraform` for infrastructure provisioning
|
|
|
|
### Usage
|
|
|
|
1. **Clone:** `git clone git@github.com:RWejlgaard/pez-infra.git`
|
|
2. **Services:** Each service has its own directory under `ansible/services/` with a `docker-compose.yml` and config files
|
|
3. **Deploy:** Ansible playbooks in `ansible/` handle deployment (see individual playbook docs)
|
|
4. **Infrastructure:** Terraform configs in `terraform/` manage DNS and cloud resources
|
|
|
|
### Secrets
|
|
|
|
Secrets are encrypted in-repo using [SOPS](https://github.com/getsops/sops) + [age](https://github.com/FiloSottile/age). Encrypted files use `.enc.` in their extension (e.g. `secrets.enc.yml`). See **[Secrets Management](docs/secrets.md)** for full setup and usage instructions.
