## 💾 Storage & Persistence (`/mnt/data`)

All persistent data and configuration files are stored in `/mnt/data` on the host.

| Host Path | Container Path | Purpose | Type |
|-----------|----------------|---------|------|
| `/mnt/data/gohorsejobs/backend/.env` | (Injected Env) | **Backend Config:** Secrets, DB URL, Port settings. | File |
| `/mnt/data/gohorsejobs/backoffice/.env` | (Injected Env) | **Backoffice Config:** Secrets, DB URL. | File |
| `/mnt/data/gohorsejobs/seeder-api/.env` | (Injected Env) | **Seeder Config:** Secrets, DB URL. | File |
| `/mnt/data/postgres-general` | `/var/lib/postgresql/data` | **Database Storage:** Main storage for `postgres-main` container. Contains `gohorsejobs_dev` DB. | Directory |

> **Backup Note:** To backup the environment, ensure `/mnt/data/gohorsejobs` and `/mnt/data/postgres-general` are included in snapshots.

## 🌍 Service Maps & Networking

### 🚦 Traefik Routing
Services are exposed via Traefik labels defined in the Quadlet `.container` files.

| Domain | Service | Internal Port | Host Port (Debug) |
|--------|---------|---------------|-------------------|
| `dev.gohorsejobs.com` | `gohorsejobs-frontend-dev` | `3000` | `8523` |
| `api-tmp.gohorsejobs.com` | `gohorsejobs-backend-dev` | `8521` | `8521` |
| `b-tmp.gohorsejobs.com` | `gohorsejobs-backoffice-dev` | `3001` | - |
| `seeder.gohorsejobs.com` | `gohorsejobs-seeder-dev` | `8080` | `8522` |

### 🛑 Security
- **Backend/Seeder/Frontend** expose ports to the Host (`85xx`) for debugging/direct access if needed.
- **Backoffice** is *only* accessible via Traefik (internal network).
- **PostgreSQL** is *only* accessible internally via `web_proxy` network (no host port binding).

## 🛠️ Operational Guide

### 1. View & Manage Configs
Configurations are **not** inside containers. Edit them on the host:
```bash
# Edit Backend Config
vim /mnt/data/gohorsejobs/backend/.env

# Apply changes
systemctl restart gohorsejobs-backend-dev
```

### 2. Full Environment Restart
To restart all GoHorseJobs related services (excluding Database):
```bash
systemctl restart gohorsejobs-backend-dev gohorsejobs-backoffice-dev gohorsejobs-seeder-dev gohorsejobs-frontend-dev
```

### 3. Database Access
Access the local database directly via the `postgres-main` container:
```bash
# Internal Connection
docker exec -it postgres-main psql -U yuki -d gohorsejobs_dev
```

## 🚀 Deployment Pipeline (Manual)

Current workflow uses **Local Build** -> **Forgejo Registry** -> **Server Pull**.

### 1. Build & Push (Local Machine)
```bash
# Login
podman login forgejo-gru.rede5.com.br

# Build
cd backend
podman build -t forgejo-gru.rede5.com.br/rede5/gohorsejobs-backend:latest .

# Push
podman push forgejo-gru.rede5.com.br/rede5/gohorsejobs-backend:latest
```

### 2. Deploy (On Apolo Server)
```bash
ssh root@apolo

# Pull new image
podman pull forgejo-gru.rede5.com.br/rede5/gohorsejobs-backend:latest

# Restart service (Systemd handles container recreation)
systemctl restart gohorsejobs-backend-dev
```
