    - Fixed TierLimitExceededException import and Pydantic @field_validator bugs
    - `wizard.lu` serving frontend with CSS over HTTPS (mixed content fixed)
    - `/merchants` and `/admin` redirect fix (CMS catch-all was intercepting)

!!! success "Progress — 2026-02-13"
    **Completed:**

    - CI fully green: ruff (lint), pytest, architecture, docs all passing
    - Pinned ruff==0.8.4 in requirements-dev.txt (CI/local version mismatch was root cause of recurring I001 errors)
    - Pre-commit hooks configured and installed (ruff auto-fix, architecture validation, trailing whitespace, end-of-file)
    - AAAA (IPv6) records added for all wizard.lu domains
    - mkdocs build clean (zero warnings) — all 32 orphan pages added to nav
    - Pre-commit documented in `docs/development/code-quality.md`
    - **Step 16: Continuous deployment** — auto-deploy on push to master via `scripts/deploy.sh` + Gitea Actions

    **Next steps:**

    - [x] Step 17: Backups
    - [x] Step 18: Monitoring & observability

    **Deferred (not urgent, do when all platforms ready):**

    - [x] ~~DNS A + AAAA records for platform domains (`omsflow.lu`, `rewardflow.lu`)~~
    - [x] ~~Uncomment platform domains in Caddyfile after DNS propagation~~

!!! success "Progress — 2026-02-14"
    **Completed:**

    - **Wizamart → Orion rename** — 1,086 occurrences replaced across 184 files (database identifiers, email addresses, domains, config, templates, docs, seed data)
    - Template renamed: `homepage-wizamart.html` → `homepage-orion.html`
    - **Production DB rebuilt from scratch** with Orion naming (`orion_db`, `orion_user`)
    - Platform domains configured in seed data: wizard.lu (main), omsflow.lu, rewardflow.lu (loyalty)
    - Docker volume explicitly named `orion_postgres_data`
    - `.dockerignore` added — prevents `.env` from being baked into Docker images
    - `env_file: .env` added to `docker-compose.yml` — containers load host env vars properly
    - `CapacitySnapshot` model import fixed (moved from billing to monitoring in `alembic/env.py`)
    - All services verified healthy at `https://api.wizard.lu/health`
    - **Step 17: Backups** — automated pg_dump scripts (daily + weekly rotation), R2 offsite upload, restore helper
    - **Step 18: Monitoring** — Prometheus, Grafana, node-exporter, cAdvisor added to docker-compose; `/metrics` endpoint activated via `prometheus_client`

!!! success "Progress — 2026-02-15"
    **Completed:**

    - **Step 17 server-side**: Hetzner backups enabled (5 of 7 daily images, last 6.22 GB)
    - **Step 18 server-side**: Full monitoring stack deployed — Prometheus (4/4 targets up), Grafana at `https://grafana.wizard.lu` with Node Exporter Full (#1860) and Docker/cAdvisor (#193) dashboards
    - **Domain rename**: `oms.lu` → `omsflow.lu`, `loyalty.lu` → `rewardflow.lu` across entire codebase (19 + 13 files)
    - **Platform domains live**: all three platforms serving HTTPS via Caddy with auto-SSL
        - `https://wizard.lu` (main)
        - `https://omsflow.lu` (OMS)
        - `https://rewardflow.lu` (Loyalty+)
    - Platform `domain` column updated in production DB
    - RAM usage ~2.4 GB on 4 GB server (stable, CI jobs add ~550 MB temporarily)

    **Remaining:**

    - [ ] Cloudflare R2 offsite backup setup (create account + bucket, configure `awscli`, add `--upload` to systemd timer)
    - [ ] Systemd backup timer (`orion-backup.timer`) — daily at 03:00

---

## Step 1: Initial Server Access

```bash
ssh root@91.99.65.229
```

## Step 2: Create Non-Root User

Create a dedicated user with sudo privileges and copy the SSH key:

```bash
# Create user
adduser samir
usermod -aG sudo samir

# Copy SSH keys to new user
rsync --archive --chown=samir:samir ~/.ssh /home/samir
```

Verify by connecting as the new user (from a **new terminal**):

```bash
ssh samir@91.99.65.229
```

## Step 3: System Update & Essential Packages

```bash
sudo apt update && sudo apt upgrade -y

sudo apt install -y \
    curl \
    git \
    wget \
    ufw \
    fail2ban \
    htop \
    unzip \
    make
```

Reboot if a kernel upgrade is pending:

```bash
sudo reboot
```

## Step 4: Firewall Configuration (UFW)

```bash
sudo ufw allow OpenSSH
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
```

Verify:

```bash
sudo ufw status
```

Expected output:

```
Status: active

To                         Action      From
--                         ------      ----
OpenSSH                    ALLOW       Anywhere
80/tcp                     ALLOW       Anywhere
443/tcp                    ALLOW       Anywhere
```

## Step 5: Harden SSH

!!! warning "Before doing this step"
    Make sure you can SSH as `samir` from another terminal first!
    If you lock yourself out, you'll need to use Hetzner's console rescue mode.

```bash
sudo sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin no/' /etc/ssh/sshd_config
sudo sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config
sudo systemctl restart ssh    # Note: Ubuntu 24.04 uses 'ssh' not 'sshd'
```

## Step 6: Install Docker & Docker Compose

```bash
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker samir
```

Log out and back in for the group change:

```bash
exit
# Then: ssh samir@91.99.65.229
```

Verify:

```bash
docker --version
docker compose version
```

## Step 7: Gitea (Self-Hosted Git)

Create the Gitea directory and compose file:

```bash
mkdir -p ~/gitea && cd ~/gitea
```

Create `docker-compose.yml` with `nano ~/gitea/docker-compose.yml`:

```yaml
services:
  gitea:
    image: gitea/gitea:latest
    container_name: gitea
    restart: always
    environment:
      - USER_UID=1000
      - USER_GID=1000
      - GITEA__database__DB_TYPE=postgres
      - GITEA__database__HOST=gitea-db:5432
      - GITEA__database__NAME=gitea
      - GITEA__database__USER=gitea
      - GITEA__database__PASSWD=<GENERATED_PASSWORD>
      - GITEA__server__ROOT_URL=http://91.99.65.229:3000/
      - GITEA__server__SSH_DOMAIN=91.99.65.229
      - GITEA__server__DOMAIN=91.99.65.229
      - GITEA__actions__ENABLED=true
    volumes:
      - gitea-data:/data
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    ports:
      - "3000:3000"
      - "2222:22"
    depends_on:
      gitea-db:
        condition: service_healthy

  gitea-db:
    image: postgres:15
    container_name: gitea-db
    restart: always
    environment:
      POSTGRES_DB: gitea
      POSTGRES_USER: gitea
      POSTGRES_PASSWORD: <GENERATED_PASSWORD>
    volumes:
      - gitea-db-data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U gitea"]
      interval: 10s
      timeout: 5s
      retries: 5

volumes:
  gitea-data:
  gitea-db-data:
```

Generate the database password with `openssl rand -hex 16` and replace `<GENERATED_PASSWORD>` in both places.

Open the firewall for Gitea and start:

```bash
sudo ufw allow 3000/tcp
docker compose up -d
docker compose ps
```

Visit `http://91.99.65.229:3000` and complete the setup wizard. Create an admin account (e.g. `sboulahtit`).

Then create a repository (e.g. `orion`).

## Step 8: Push Repository to Gitea

### Add SSH Key to Gitea

Before pushing via SSH, add your local machine's public key to Gitea:

1. Copy your public key:

    ```bash
    cat ~/.ssh/id_ed25519.pub
    # Or if using RSA: cat ~/.ssh/id_rsa.pub
    ```

2. In the Gitea web UI: click your avatar → **Settings** → **SSH / GPG Keys** → **Add Key** → paste the key.

3. Add the Gitea SSH host to known hosts:

    ```bash
    ssh-keyscan -p 2222 git.wizard.lu >> ~/.ssh/known_hosts
    ```

### Add Remote and Push

From your **local machine**:

```bash
cd /home/samir/Documents/PycharmProjects/letzshop-product-import
git remote add gitea ssh://git@git.wizard.lu:2222/sboulahtit/orion.git
git push gitea master
```

!!! note "Remote URL updated"
    The remote was initially set to `http://91.99.65.229:3000/...` during setup.
    After Caddy was configured, it was updated to use the domain with SSH:
    `ssh://git@git.wizard.lu:2222/sboulahtit/orion.git`

    To update an existing remote:
    ```bash
    git remote set-url gitea ssh://git@git.wizard.lu:2222/sboulahtit/orion.git
    ```

## Step 9: Clone Repository on Server

```bash
mkdir -p ~/apps
cd ~/apps
git clone http://localhost:3000/sboulahtit/orion.git
cd orion
```

## Step 10: Configure Production Environment

```bash
cp .env.example .env
nano .env
```

### Critical Production Values

Generate secrets:

```bash
openssl rand -hex 32   # For JWT_SECRET_KEY
openssl rand -hex 16   # For database password
```

| Variable | How to Generate / What to Set |
|---|---|
| `DEBUG` | `False` |
| `DATABASE_URL` | `postgresql://orion_user:YOUR_DB_PW@db:5432/orion_db` |
| `JWT_SECRET_KEY` | Output of `openssl rand -hex 32` |
| `ADMIN_PASSWORD` | Strong password |
| `USE_CELERY` | `true` |
| `REDIS_URL` | `redis://redis:6379/0` |
| `STRIPE_SECRET_KEY` | Your Stripe secret key (configure later) |
| `STRIPE_PUBLISHABLE_KEY` | Your Stripe publishable key (configure later) |
| `STRIPE_WEBHOOK_SECRET` | Your Stripe webhook secret (configure later) |
| `STORAGE_BACKEND` | `r2` (if using Cloudflare R2, configure later) |

Also update the PostgreSQL password in `docker-compose.yml` (lines 9 and 40) to match.

## Step 11: Deploy with Docker Compose

```bash
cd ~/apps/orion

# Create directories with correct permissions for the container user
mkdir -p logs uploads exports
sudo chown -R 1000:1000 logs uploads exports

# Start infrastructure first
docker compose up -d db redis

# Wait for health checks to pass
docker compose ps

# Build and start the full stack
docker compose --profile full up -d --build
```

Verify all services are running:

```bash
docker compose --profile full ps
```

Expected: `api` (healthy), `db` (healthy), `redis` (healthy), `celery-worker` (healthy), `celery-beat` (running), `flower` (running).

## Step 12: Initialize Database

!!! note "PYTHONPATH required"
    The seed scripts need `PYTHONPATH=/app` set explicitly when running inside the container.

```bash
# Run migrations (use 'heads' for multi-branch Alembic)
docker compose --profile full exec -e PYTHONPATH=/app api python -m alembic upgrade heads

# Seed production data
docker compose --profile full exec -e PYTHONPATH=/app api python scripts/seed/init_production.py
docker compose --profile full exec -e PYTHONPATH=/app api python scripts/seed/init_log_settings.py
docker compose --profile full exec -e PYTHONPATH=/app api python scripts/seed/create_default_content_pages.py
docker compose --profile full exec -e PYTHONPATH=/app api python scripts/seed/seed_email_templates.py
```

### Seeded Data Summary

| Data | Count |
|---|---|
| Admin users | 1 (`admin@wizard.lu`) |
| Platforms | 3 (OMS, Main, Loyalty+) |
| Admin settings | 15 |
| Subscription tiers | 4 (Essential, Professional, Business, Enterprise) |
| Log settings | 6 |
| CMS pages | 8 (About, Contact, FAQ, Shipping, Returns, Privacy, Terms, Homepage) |
| Email templates | 17 (4 languages: en, fr, de, lb) |

---

## Step 13: DNS Configuration

Before setting up Caddy, point your domain's DNS to the server.

### wizard.lu (Main Platform) — Completed

| Type | Name | Value | TTL |
|---|---|---|---|
| A | `@` | `91.99.65.229` | 300 |
| A | `www` | `91.99.65.229` | 300 |
| A | `api` | `91.99.65.229` | 300 |
| A | `git` | `91.99.65.229` | 300 |
| A | `flower` | `91.99.65.229` | 300 |

### omsflow.lu (OMS Platform) — Completed

| Type | Name | Value | TTL |
|---|---|---|---|
| A | `@` | `91.99.65.229` | 300 |
| A | `www` | `91.99.65.229` | 300 |
| AAAA | `@` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `www` | `2a01:4f8:1c1a:b39c::1` | 300 |

### rewardflow.lu (Loyalty+ Platform) — Completed

| Type | Name | Value | TTL |
|---|---|---|---|
| A | `@` | `91.99.65.229` | 300 |
| A | `www` | `91.99.65.229` | 300 |
| AAAA | `@` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `www` | `2a01:4f8:1c1a:b39c::1` | 300 |

### IPv6 (AAAA) Records — TODO

Optional but recommended. Add AAAA records for all domains above, pointing to the server's IPv6 address. Verify your IPv6 address first:

```bash
ip -6 addr show eth0 | grep 'scope global'
```

It should match the value in the Hetzner Cloud Console (Networking tab). Then create AAAA records mirroring each A record above, e.g.:

| Type | Name (wizard.lu) | Value | TTL |
|---|---|---|---|
| AAAA | `@` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `www` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `api` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `git` | `2a01:4f8:1c1a:b39c::1` | 300 |
| AAAA | `flower` | `2a01:4f8:1c1a:b39c::1` | 300 |

Repeat for `omsflow.lu` and `rewardflow.lu`.

!!! tip "DNS propagation"
    Set TTL to 300 (5 minutes) initially. DNS changes can take up to 24 hours to propagate globally, but usually complete within 30 minutes. Verify with: `dig api.wizard.lu +short`

## Step 14: Reverse Proxy with Caddy

Install Caddy:

```bash
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' \
    | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' \
    | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update && sudo apt install caddy
```

### Caddyfile Configuration

Edit `/etc/caddy/Caddyfile`:

```caddy
# ─── Platform 1: Main (wizard.lu) ───────────────────────────
wizard.lu {
    reverse_proxy localhost:8001
}

www.wizard.lu {
    redir https://wizard.lu{uri} permanent
}

# ─── Platform 2: OMS (omsflow.lu) ───────────────────────────────
omsflow.lu {
    reverse_proxy localhost:8001
}

www.omsflow.lu {
    redir https://omsflow.lu{uri} permanent
}

# ─── Platform 3: Loyalty+ (rewardflow.lu) ──────────────────
rewardflow.lu {
    reverse_proxy localhost:8001
}

www.rewardflow.lu {
    redir https://rewardflow.lu{uri} permanent
}

# ─── Services ───────────────────────────────────────────────
api.wizard.lu {
    reverse_proxy localhost:8001
}

git.wizard.lu {
    reverse_proxy localhost:3000
}

flower.wizard.lu {
    reverse_proxy localhost:5555
}
```

!!! info "How multi-platform routing works"
    All platform domains (`wizard.lu`, `omsflow.lu`, `rewardflow.lu`) point to the **same FastAPI backend** on port 8001. The `PlatformContextMiddleware` reads the `Host` header to detect which platform the request is for. Caddy preserves the Host header by default, so no extra configuration is needed.

    The `domain` column in the `platforms` database table must match:

    | Platform | code | domain |
    |---|---|---|
    | Main | `main` | `wizard.lu` |
    | OMS | `oms` | `omsflow.lu` |
    | Loyalty+ | `loyalty` | `rewardflow.lu` |

Start Caddy:

```bash
sudo systemctl restart caddy
```

Caddy automatically provisions Let's Encrypt SSL certificates for all configured domains.

Verify:

```bash
curl -I https://wizard.lu
curl -I https://api.wizard.lu/health
curl -I https://git.wizard.lu
```

After Caddy is working, remove the temporary firewall rules:

```bash
sudo ufw delete allow 3000/tcp
sudo ufw delete allow 8001/tcp
```

Update Gitea's configuration to use its new domain. In `~/gitea/docker-compose.yml`, change:

```yaml
- GITEA__server__ROOT_URL=https://git.wizard.lu/
- GITEA__server__SSH_DOMAIN=git.wizard.lu
- GITEA__server__DOMAIN=git.wizard.lu
```

Then restart Gitea:

```bash
cd ~/gitea && docker compose up -d gitea
```

### Future: Multi-Tenant Store Routing

Stores on each platform use two routing modes:

- **Standard (subdomain)**: `acme.omsflow.lu` — included in the base subscription
- **Premium (custom domain)**: `acme.lu` — available with premium subscription tiers

Both modes are handled by the `StoreContextMiddleware` which reads the `Host` header, so Caddy just needs to forward requests and preserve the header.

#### Wildcard Subdomains (for store subdomains)

When stores start using subdomains like `acme.omsflow.lu`, add wildcard blocks:

```caddy
*.omsflow.lu {
    reverse_proxy localhost:8001
}

*.rewardflow.lu {
    reverse_proxy localhost:8001
}

*.wizard.lu {
    reverse_proxy localhost:8001
}
```

!!! warning "Wildcard SSL requires DNS challenge"
    Let's Encrypt cannot issue wildcard certificates via HTTP challenge. Wildcard certs require a **DNS challenge**, which means installing a Caddy DNS provider plugin (e.g. `caddy-dns/cloudflare`) and configuring API credentials for your DNS provider. See [Caddy DNS challenge docs](https://caddyserver.com/docs/automatic-https#dns-challenge).

#### Custom Store Domains (for premium stores)

When premium stores bring their own domains (e.g. `acme.lu`), use Caddy's **on-demand TLS**:

```caddy
https:// {
    tls {
        on_demand
    }
    reverse_proxy localhost:8001
}
```

On-demand TLS auto-provisions SSL certificates when a new domain connects. Add an `ask` endpoint to validate that the domain is registered in the `store_domains` table, preventing abuse:

```caddy
tls {
    on_demand
    ask http://localhost:8001/api/v1/internal/verify-domain
}
```

!!! note "Not needed yet"
    Wildcard subdomains and custom domains are future work. The current Caddyfile handles all platform root domains and service subdomains.

## Step 15: Gitea Actions Runner

!!! warning "ARM64 architecture"
    This server is ARM64. Download the `arm64` binary, not `amd64`.

Download and install:

```bash
mkdir -p ~/gitea-runner && cd ~/gitea-runner

# Download act_runner v0.2.13 (ARM64)
wget https://gitea.com/gitea/act_runner/releases/download/v0.2.13/act_runner-0.2.13-linux-arm64
chmod +x act_runner-0.2.13-linux-arm64
ln -s act_runner-0.2.13-linux-arm64 act_runner
```

Register the runner (get token from **Site Administration > Actions > Runners > Create new Runner**):

```bash
./act_runner register \
    --instance https://git.wizard.lu \
    --token YOUR_RUNNER_TOKEN
```

Accept the default runner name and labels when prompted.

Create a systemd service for persistent operation:

```bash
sudo nano /etc/systemd/system/gitea-runner.service
```

```ini
[Unit]
Description=Gitea Actions Runner
After=network.target

[Service]
Type=simple
User=samir
WorkingDirectory=/home/samir/gitea-runner
ExecStart=/home/samir/gitea-runner/act_runner daemon
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
```

Enable and start:

```bash
sudo systemctl daemon-reload
sudo systemctl enable --now gitea-runner
sudo systemctl status gitea-runner
```

Verify the runner shows as **Online** in Gitea: **Site Administration > Actions > Runners**.

## Step 16: Continuous Deployment

Automate deployment on every successful push to master. The Gitea Actions runner and the app both run on the same server, so the deploy job SSHes from the CI Docker container to `172.17.0.1` (Docker bridge gateway — see note in 16.2).

```
push to master
  ├── ruff ──────┐
  ├── pytest ────┤
  └── validate ──┤
                 └── deploy (SSH → scripts/deploy.sh)
                          ├── git stash / pull / pop
                          ├── docker compose up -d --build
                          ├── alembic upgrade heads
                          └── health check (retries)
```

### 16.1 Generate Deploy SSH Key (on server)

```bash
ssh-keygen -t ed25519 -C "gitea-deploy@wizard.lu" -f ~/.ssh/deploy_ed25519 -N ""
cat ~/.ssh/deploy_ed25519.pub >> ~/.ssh/authorized_keys
```

### 16.2 Add Gitea Secrets

In **Repository Settings > Actions > Secrets**, add:

| Secret | Value |
|---|---|
| `DEPLOY_SSH_KEY` | Contents of `~/.ssh/deploy_ed25519` (private key) |
| `DEPLOY_HOST` | `172.17.0.1` (Docker bridge gateway — **not** `127.0.0.1`) |
| `DEPLOY_USER` | `samir` |
| `DEPLOY_PATH` | `/home/samir/apps/orion` |

!!! important "Why `172.17.0.1` and not `127.0.0.1`?"
    CI jobs run inside Docker containers where `127.0.0.1` is the container, not the host. `172.17.0.1` is the Docker bridge gateway that routes to the host. Ensure the firewall allows SSH from the Docker bridge network: `sudo ufw allow from 172.17.0.0/16 to any port 22`. When Gitea and Orion are on separate servers, replace with the Orion server's IP.

### 16.3 Deploy Script

The deploy script lives at `scripts/deploy.sh` in the repository. It:

1. Stashes local changes (preserves `.env`)
2. Pulls latest code (`--ff-only`)
3. Pops stash to restore local changes
4. Rebuilds and restarts Docker containers (`docker compose --profile full up -d --build`)
5. Runs database migrations (`alembic upgrade heads`)
6. Health checks `http://localhost:8001/health` with 12 retries (60s total)

Exit codes: `0` success, `1` git pull failed, `2` docker compose failed, `3` migration failed, `4` health check failed.

### 16.4 CI Workflow

The deploy job in `.gitea/workflows/ci.yml` runs only on master push, after `ruff`, `pytest`, and `validate` pass:

```yaml
deploy:
  runs-on: ubuntu-latest
  if: github.event_name == 'push' && github.ref == 'refs/heads/master'
  needs: [ruff, pytest, validate]
  steps:
    - name: Deploy to production
      uses: appleboy/ssh-action@v1
      with:
        host: ${{ secrets.DEPLOY_HOST }}
        username: ${{ secrets.DEPLOY_USER }}
        key: ${{ secrets.DEPLOY_SSH_KEY }}
        port: 22
        command_timeout: 10m
        script: cd ${{ secrets.DEPLOY_PATH }} && bash scripts/deploy.sh
```

### 16.5 Manual Fallback

If CI is down, deploy manually:

```bash
cd ~/apps/orion && bash scripts/deploy.sh
```

### 16.6 Verify

```bash
# All app containers running
cd ~/apps/orion && docker compose --profile full ps

# API health (via Caddy with SSL)
curl https://api.wizard.lu/health

# Main platform
curl -I https://wizard.lu

# Gitea
curl -I https://git.wizard.lu

# Flower
curl -I https://flower.wizard.lu

# Gitea runner status
sudo systemctl status gitea-runner
```

## Step 17: Backups

Three layers of backup protection: Hetzner server snapshots, automated PostgreSQL dumps with local rotation, and offsite sync to Cloudflare R2.

### 17.1 Enable Hetzner Server Backups

In the Hetzner Cloud Console:

1. Go to **Servers** > select your server > **Backups**
2. Click **Enable backups** (~20% of server cost, ~1.20 EUR/mo for CAX11)
3. Hetzner takes automatic weekly snapshots with 7-day retention

This covers full-disk recovery (OS, Docker volumes, config files) but is coarse-grained. Database-level backups (below) give finer restore granularity.

### 17.2 Cloudflare R2 Setup (Offsite Backup Storage)

R2 provides S3-compatible object storage with a generous free tier (10 GB storage, 10 million reads/month).

**Create Cloudflare account and R2 bucket:**

1. Sign up at [cloudflare.com](https://dash.cloudflare.com/sign-up) (free account)
2. Go to **R2 Object Storage** > **Create bucket**
3. Name: `orion-backups`, region: automatic
4. Go to **R2** > **Manage R2 API Tokens** > **Create API token**
    - Permissions: Object Read & Write
    - Specify bucket: `orion-backups`
5. Note the **Account ID**, **Access Key ID**, and **Secret Access Key**

**Install and configure AWS CLI on the server:**

```bash
sudo apt install -y awscli
aws configure --profile r2
# Access Key ID: <from step 5>
# Secret Access Key: <from step 5>
# Default region name: auto
# Default output format: json
```

**Test connectivity:**

```bash
aws s3 ls --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com --profile r2
```

Add the R2 backup bucket name to your production `.env`:

```bash
R2_BACKUP_BUCKET=orion-backups
```

### 17.3 Backup Script

The backup script at `scripts/backup.sh` handles:

- `pg_dump` of Orion DB (via `docker exec orion-db-1`)
- `pg_dump` of Gitea DB (via `docker exec gitea-db`)
- On Sundays: copies daily backup to `weekly/` subdirectory
- Rotation: keeps 7 daily, 4 weekly backups
- Optional `--upload` flag: syncs to Cloudflare R2

```bash
# Create backup directories
mkdir -p ~/backups/{orion,gitea}/{daily,weekly}

# Run a manual backup
bash ~/apps/orion/scripts/backup.sh

# Run with R2 upload
bash ~/apps/orion/scripts/backup.sh --upload

# Verify backup integrity
ls -lh ~/backups/orion/daily/
gunzip -t ~/backups/orion/daily/*.sql.gz
```

### 17.4 Systemd Timer (Daily at 03:00)

Create the service unit:

```bash
sudo nano /etc/systemd/system/orion-backup.service
```

```ini
[Unit]
Description=Orion database backup
After=docker.service

[Service]
Type=oneshot
User=samir
ExecStart=/usr/bin/bash /home/samir/apps/orion/scripts/backup.sh --upload
StandardOutput=journal
StandardError=journal
```

Create the timer:

```bash
sudo nano /etc/systemd/system/orion-backup.timer
```

```ini
[Unit]
Description=Run Orion backup daily at 03:00

[Timer]
OnCalendar=*-*-* 03:00:00
Persistent=true

[Install]
WantedBy=timers.target
```

Enable and start:

```bash
sudo systemctl daemon-reload
sudo systemctl enable --now orion-backup.timer

# Verify timer is active
systemctl list-timers orion-backup.timer

# Test manually
sudo systemctl start orion-backup.service
journalctl -u orion-backup.service --no-pager
```

### 17.5 Restore Procedure

The restore script at `scripts/restore.sh` handles the full restore cycle:

```bash
# Restore Orion database
bash ~/apps/orion/scripts/restore.sh orion ~/backups/orion/daily/orion_20260214_030000.sql.gz

# Restore Gitea database
bash ~/apps/orion/scripts/restore.sh gitea ~/backups/gitea/daily/gitea_20260214_030000.sql.gz
```

The script will:

1. Stop app containers (keep DB running)
2. Drop and recreate the database
3. Restore from the `.sql.gz` backup
4. Run Alembic migrations (Orion only)
5. Restart all containers

To restore from R2 (if local backups are lost):

```bash
# Download from R2
aws s3 sync s3://orion-backups/ ~/backups/ \
    --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com \
    --profile r2

# Then restore as usual
bash ~/apps/orion/scripts/restore.sh orion ~/backups/orion/daily/<latest>.sql.gz
```

### 17.6 Verification

```bash
# Backup files exist
ls -lh ~/backups/orion/daily/
ls -lh ~/backups/gitea/daily/

# Backup integrity
gunzip -t ~/backups/orion/daily/*.sql.gz

# Timer is scheduled
systemctl list-timers orion-backup.timer

# R2 sync (if configured)
aws s3 ls s3://orion-backups/ --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com --profile r2 --recursive
```

## Step 18: Monitoring & Observability

Prometheus + Grafana monitoring stack with host and container metrics.

### Architecture

```
┌──────────────┐     scrape      ┌─────────────────┐
│  Prometheus  │◄────────────────│  Orion API       │ /metrics
│  :9090       │◄────────────────│  node-exporter   │ :9100
│              │◄────────────────│  cAdvisor        │ :8080
└──────┬───────┘                 └─────────────────┘
       │ query
┌──────▼───────┐
│   Grafana    │──── https://grafana.wizard.lu
│   :3001      │
└──────────────┘
```

### Resource Budget (4 GB Server)

| Container | RAM Limit | Purpose |
|---|---|---|
| prometheus | 256 MB | Metrics storage (15-day retention, 2 GB max) |
| grafana | 192 MB | Dashboards (SQLite backend) |
| node-exporter | 64 MB | Host CPU/RAM/disk metrics |
| cadvisor | 128 MB | Per-container resource metrics |
| **Total new** | **640 MB** | |

Existing stack ~1.8 GB + 640 MB new = ~2.4 GB. Leaves ~1.6 GB for OS. If too tight, live-upgrade to CAX21 (8 GB/80 GB, ~7.50 EUR/mo) via **Cloud Console > Server > Rescale** (~2 min restart).

### 18.1 DNS Record

Add A and AAAA records for `grafana.wizard.lu`:

| Type | Name | Value | TTL |
|---|---|---|---|
| A | `grafana` | `91.99.65.229` | 300 |
| AAAA | `grafana` | `2a01:4f8:1c1a:b39c::1` | 300 |

### 18.2 Caddy Configuration

Add to `/etc/caddy/Caddyfile`:

```caddy
grafana.wizard.lu {
    reverse_proxy localhost:3001
}
```

Reload Caddy:

```bash
sudo systemctl reload caddy
```

### 18.3 Production Environment

Add to `~/apps/orion/.env`:

```bash
ENABLE_METRICS=true
GRAFANA_URL=https://grafana.wizard.lu
GRAFANA_ADMIN_USER=admin
GRAFANA_ADMIN_PASSWORD=<strong-password>
```

### 18.4 Deploy

```bash
cd ~/apps/orion
docker compose --profile full up -d --build
```

Verify all containers are running:

```bash
docker compose --profile full ps
docker stats --no-stream
```

### 18.5 Grafana First Login

1. Open `https://grafana.wizard.lu`
2. Login with `admin` / `<password from .env>`
3. Change the default password when prompted

**Import community dashboards:**

- **Node Exporter Full**: Dashboards > Import > ID `1860` > Select Prometheus datasource
- **Docker / cAdvisor**: Dashboards > Import > ID `193` > Select Prometheus datasource

### 18.6 Verification

```bash
# Prometheus metrics from Orion API
curl -s https://api.wizard.lu/metrics | head -5

# Health endpoints
curl -s https://api.wizard.lu/health/live
curl -s https://api.wizard.lu/health/ready

# Prometheus targets (all should be "up")
curl -s http://localhost:9090/api/v1/targets | python3 -m json.tool | grep health

# Grafana accessible
curl -I https://grafana.wizard.lu

# RAM usage within limits
docker stats --no-stream
```

```

## Troubleshooting

### Permission denied on logs

The Docker container runs as `appuser` (UID 1000). Host-mounted volumes need matching ownership:

```bash
sudo chown -R 1000:1000 logs uploads exports
```

### Celery workers restarting

Check logs for import errors:

```bash
docker compose --profile full logs celery-worker --tail 30
```

Common cause: stale task module references in `app/core/celery_config.py`.

### SSH service name on Ubuntu 24.04

Ubuntu 24.04 uses `ssh` not `sshd`:

```bash
sudo systemctl restart ssh    # correct
sudo systemctl restart sshd   # will fail
```

### git pull fails with local changes

If `docker-compose.yml` was edited on the server (e.g. passwords), stash before pulling:

```bash
git stash
git pull
git stash pop
```

## Maintenance

### Deploy updates

Deployments happen automatically when pushing to master (see [Step 16](#step-16-continuous-deployment)). For manual deploys:

```bash
cd ~/apps/orion && bash scripts/deploy.sh
```

The script handles stashing local changes, pulling, rebuilding containers, running migrations, and health checks.

### View logs

```bash
# Follow all logs in real-time
docker compose --profile full logs -f

# Follow a specific service
docker compose --profile full logs -f api
docker compose --profile full logs -f celery-worker
docker compose --profile full logs -f celery-beat
docker compose --profile full logs -f flower

# View last N lines (useful for debugging crashes)
docker compose --profile full logs --tail=50 api
docker compose --profile full logs --tail=100 celery-worker

# Filter logs for errors
docker compose --profile full logs api | grep -i "error\|exception\|failed"
```

### Check container status

```bash
# Overview of all containers (health, uptime, ports)
docker compose --profile full ps

# Watch for containers stuck in "Restarting" — indicates a crash loop
# Healthy containers show: Up Xs (healthy)
```

### Restart services

```bash
# Restart a single service
docker compose --profile full restart api

# Restart everything
docker compose --profile full restart

# Full rebuild (after code changes)
docker compose --profile full up -d --build
```

### Quick access URLs

After Caddy is configured:

| Service | URL |
|---|---|
| Main Platform | `https://wizard.lu` |
| API Swagger docs | `https://api.wizard.lu/docs` |
| API ReDoc | `https://api.wizard.lu/redoc` |
| Admin panel | `https://wizard.lu/admin/login` |
| Health check | `https://api.wizard.lu/health` |
| Prometheus metrics | `https://api.wizard.lu/metrics` |
| Gitea | `https://git.wizard.lu` |
| Flower | `https://flower.wizard.lu` |
| Grafana | `https://grafana.wizard.lu` |
| OMS Platform | `https://omsflow.lu` |
| Loyalty+ Platform | `https://rewardflow.lu` |

Direct IP access (temporary, until firewall rules are removed):

| Service | URL |
|---|---|
| API | `http://91.99.65.229:8001/docs` |
| Gitea | `http://91.99.65.229:3000` |
| Flower | `http://91.99.65.229:5555` |
