- `python3-pip` and `awscli` installed on server (pip user install, PATH added to `.bashrc` and systemd service)

**Steps 1–18 fully complete.** All infrastructure operational.

!!! success "Progress — 2026-02-15 (continued)" Completed (Steps 19–24):

- **Step 19: Prometheus Alerting** — alert rules (host, container, API, Celery, targets) + Alertmanager with email routing

---

Step 1: Initial Server Access

ssh root@91.99.65.229

Step 2: Create Non-Root User

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

# 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):

ssh samir@91.99.65.229

Step 3: System Update & Essential Packages

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:

sudo reboot

Step 4: Firewall Configuration (UFW)

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

Verify:

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.

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

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

Log out and back in for the group change:

exit
# Then: ssh samir@91.99.65.229

Verify:

docker --version
docker compose version

Step 7: Gitea (Self-Hosted Git)

Create the Gitea directory and compose file:

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

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

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:

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:

   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:

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

Add Remote and Push

From your local machine:

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

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

Step 10: Configure Production Environment

cp .env.example .env
nano .env

Critical Production Values

Generate secrets:

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

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:

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.

# 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 — Completed

AAAA records are included in the DNS tables above for all domains. To verify your IPv6 address:

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:

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:

# ─── 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:

sudo systemctl restart caddy

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

Verify:

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:

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:

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

Then restart Gitea:

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:

*.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.

Custom Store Domains (for premium stores)

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

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:

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:

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):

./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:

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

[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:

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).

16.1 Generate Deploy SSH Key (on server)

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:

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:

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

16.6 Verify

# 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 (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:

# awscli is not available via apt on Ubuntu 24.04; install via pip
sudo apt install -y python3-pip
pip3 install awscli --break-system-packages

# Add ~/.local/bin to PATH (pip installs binaries there)
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

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:

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

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

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

# 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:

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

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

[Service]
Type=oneshot
User=samir
Environment="PATH=/home/samir/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
ExecStart=/usr/bin/bash /home/samir/apps/orion/scripts/backup.sh --upload
StandardOutput=journal
StandardError=journal

Create the timer:

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

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

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

[Install]
WantedBy=timers.target

Enable and start:

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:

# 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):

# 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

# 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

┌──────▼───────┐
│   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:

grafana.wizard.lu {
    reverse_proxy localhost:3001
}

Reload Caddy:

sudo systemctl reload caddy

18.3 Production Environment

Add to ~/apps/orion/.env:

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

18.4 Deploy

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

Verify all containers are running:

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

# 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

---

Step 19: Prometheus Alerting

Alert rules and Alertmanager for email notifications when things go wrong.

19.1 Architecture

┌──────────────┐  evaluates   ┌───────────────────┐
│  Prometheus  │─────────────►│  alert.rules.yml  │
│  :9090       │              │  (host, container, │
│              │              │   API, Celery)     │
└──────┬───────┘              └───────────────────┘
       │ fires alerts
┌──────▼───────┐
│ Alertmanager │──── email ──► admin@wizard.lu
│ :9093        │
└──────────────┘

19.2 Alert Rules

Alert rules are defined in monitoring/prometheus/alert.rules.yml:

Group	Alert	Condition	Severity
Host	HostHighCpuUsage	CPU >80% for 5m	warning
Host	HostHighMemoryUsage	Memory >85% for 5m	warning
Host	HostHighDiskUsage	Disk >80%	warning
Host	HostDiskFullPrediction	Disk full within 4h	critical
Containers	ContainerHighRestartCount	>3 restarts/hour	critical
Containers	ContainerOomKilled	Any OOM kill	critical
Containers	ContainerHighCpu	>80% CPU for 5m	warning
API	ApiHighErrorRate	5xx rate >1% for 5m	critical
API	ApiHighLatency	P95 >2s for 5m	warning
API	ApiHealthCheckDown	Health check failing 1m	critical
Celery	CeleryQueueBacklog	>100 tasks for 10m	warning
Prometheus	TargetDown	Any target down 2m	critical

19.3 Alertmanager Configuration

Alertmanager config is in monitoring/alertmanager/alertmanager.yml:

• Critical alerts: repeat every 1 hour
• Warning alerts: repeat every 4 hours
• Groups by alertname + severity, 30s wait, 5m interval
• Inhibition: warnings suppressed when critical is already firing for same alert

!!! warning "Configure SMTP before deploying" Edit monitoring/alertmanager/alertmanager.yml and fill in the SMTP settings (host, username, password, recipient email). Alertmanager will start but won't send emails until SMTP is configured.

19.4 Docker Compose Changes

The docker-compose.yml includes:

• alertmanager service: prom/alertmanager:latest, profiles: [full], port 127.0.0.1:9093, mem_limit: 32m
• prometheus volumes: mounts alert.rules.yml as read-only
• prometheus.yml: alerting: section pointing to alertmanager:9093, rule_files: for alert rules, new scrape job for alertmanager

19.5 Alertmanager SMTP Setup (SendGrid)

Alertmanager needs SMTP to send email notifications. SendGrid handles both transactional emails and marketing campaigns under one account — set it up once and use it for everything.

Free trial: 100 emails/day for 60 days. Covers alerting + transactional emails through launch. After 60 days, upgrade to a paid plan (Essentials starts at ~$20/mo for 50K emails/mo).

1. Create SendGrid account:

1. Sign up at sendgrid.com (free plan)
2. Complete Sender Authentication: go to Settings > Sender Authentication > Domain Authentication
3. Authenticate your sending domain (wizard.lu) — SendGrid provides CNAME records to add to DNS
4. Create an API key: Settings > API Keys > Create API Key (Full Access)
5. Save the API key — you'll need it for both Alertmanager and the app's EMAIL_PROVIDER

!!! info "SendGrid SMTP credentials" SendGrid uses a single credential pattern for SMTP:

- **Server**: `smtp.sendgrid.net`
- **Port**: `587` (STARTTLS)
- **Username**: literally the string `apikey` (not your email)
- **Password**: your API key (starts with `SG.`)

2. Update alertmanager config on the server:

nano ~/apps/orion/monitoring/alertmanager/alertmanager.yml

Replace the SMTP placeholders:

global:
  smtp_smarthost: 'smtp.sendgrid.net:587'
  smtp_from: 'alerts@wizard.lu'
  smtp_auth_username: 'apikey'
  smtp_auth_password: 'SG.your-sendgrid-api-key-here'
  smtp_require_tls: true

Update the to: addresses in both receivers to your actual email.

3. Update app email config in ~/apps/orion/.env:

# SendGrid for all application emails (password reset, order confirmation, etc.)
EMAIL_PROVIDER=sendgrid
SENDGRID_API_KEY=SG.your-sendgrid-api-key-here
EMAIL_FROM_ADDRESS=noreply@wizard.lu
EMAIL_FROM_NAME=Orion

4. Restart services:

cd ~/apps/orion
docker compose --profile full restart alertmanager api
curl -s http://localhost:9093/-/healthy  # Should return OK

5. Test by triggering a test alert (optional):

# Send a test alert to alertmanager (v2 API)
curl -X POST http://localhost:9093/api/v2/alerts -H "Content-Type: application/json" -d '[{"labels":{"alertname":"TestAlert","severity":"warning"},"annotations":{"summary":"Test alert - please ignore"},"startsAt":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","endsAt":"'$(date -u -d '+5 minutes' +%Y-%m-%dT%H:%M:%SZ)'"}]'

Check your inbox within 30 seconds. Then verify the alert resolved:

curl -s http://localhost:9093/api/v2/alerts | python3 -m json.tool

!!! tip "Alternative SMTP providers" Any SMTP service works if you prefer a different provider:

- **Amazon SES**: `email-smtp.eu-west-1.amazonaws.com:587` — cheapest at scale ($0.10/1K emails)
- **Mailgun**: `smtp.mailgun.org:587` — transactional only, no built-in marketing
- **Gmail**: `smtp.gmail.com:587` with an App Password (not recommended for production)

19.6 Deploy

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

19.7 Verification

# Alertmanager healthy
curl -s http://localhost:9093/-/healthy

# Alert rules loaded
curl -s http://localhost:9090/api/v1/rules | python3 -m json.tool | head -20

# Active alerts (should be empty if all is well)
curl -s http://localhost:9090/api/v1/alerts | python3 -m json.tool

# Alertmanager target in Prometheus
curl -s http://localhost:9090/api/v1/targets | python3 -m json.tool | grep alertmanager

19.8 Multi-Domain Email Strategy

SendGrid supports multiple authenticated domains on a single account. This enables sending emails from client domains (e.g., orders@acme.lu) without clients needing their own SendGrid plan.

Current setup:

• wizard.lu authenticated — used for platform emails (alerts@, noreply@)

Future: client domain onboarding

When a client wants emails sent from their domain (e.g., acme.lu):

1. In SendGrid: Settings > Sender Authentication > Authenticate a Domain → add acme.lu
2. SendGrid provides CNAME + TXT records
3. Client adds the DNS records to their domain
4. Verify in SendGrid

This is the professional approach — emails come from the client's domain with proper SPF/DKIM, not from wizard.lu. Build an admin flow to automate this as part of store onboarding.

!!! note "Volume planning" The free trial allows 100 emails/day. Once clients start sending marketing campaigns, upgrade to a paid SendGrid plan based on total volume across all client domains.

---

Step 20: Security Hardening

Docker network segmentation, fail2ban configuration, and automatic security updates.

20.1 Docker Network Segmentation

Three isolated networks replace the default flat network:

Network	Purpose	Services
orion_frontend	External-facing	api
orion_backend	Database + workers	db, redis, api, celery-worker, celery-beat, flower
orion_monitoring	Metrics collection	api, prometheus, grafana, node-exporter, cadvisor, alertmanager

The api service is on all three networks because it needs to:

• Serve HTTP traffic (frontend)
• Connect to database and Redis (backend)
• Expose /metrics to Prometheus (monitoring)

This is already configured in the updated docker-compose.yml. After deploying, verify:

docker network ls | grep orion
# Expected: orion_frontend, orion_backend, orion_monitoring

20.2 fail2ban Configuration

fail2ban is already installed (Step 3) but needs jail configuration. All commands below are copy-pasteable.

SSH jail — bans IPs after 3 failed SSH attempts for 24 hours:

sudo tee /etc/fail2ban/jail.local << 'EOF'
[sshd]
enabled = true
port = ssh
filter = sshd
logpath = /var/log/auth.log
maxretry = 3
bantime = 86400
findtime = 600
EOF

Caddy access logging — fail2ban needs a log file to watch. Add a global log directive to your Caddyfile:

sudo nano /etc/caddy/Caddyfile

Add this block at the very top of the Caddyfile, before any site blocks:

{
    log {
        output file /var/log/caddy/access.log {
            roll_size 100MiB
            roll_keep 5
        }
        format json
    }
}

Create the log directory and restart Caddy:

sudo mkdir -p /var/log/caddy
sudo chown caddy:caddy /var/log/caddy
sudo systemctl restart caddy
sudo systemctl status caddy

# Verify logging works (make a request, then check)
curl -s https://wizard.lu > /dev/null
sudo tail -1 /var/log/caddy/access.log | python3 -m json.tool | head -5

Caddy auth filter — matches 401/403 responses in Caddy's JSON logs:

sudo tee /etc/fail2ban/filter.d/caddy-auth.conf << 'EOF'
[Definition]
failregex = ^.*"remote_ip":"<HOST>".*"status":(401|403).*$
ignoreregex =
EOF

Caddy jail — bans IPs after 10 failed auth attempts for 1 hour:

sudo tee /etc/fail2ban/jail.d/caddy.conf << 'EOF'
[caddy-auth]
enabled = true
port = http,https
filter = caddy-auth
logpath = /var/log/caddy/access.log
maxretry = 10
bantime = 3600
findtime = 600
EOF

Restart and verify:

sudo systemctl restart fail2ban

# Both jails should be listed
sudo fail2ban-client status

# SSH jail details
sudo fail2ban-client status sshd

# Caddy jail details (will show 0 bans initially)
sudo fail2ban-client status caddy-auth

20.3 Unattended Security Upgrades

Install and enable automatic security updates:

sudo apt install -y unattended-upgrades apt-listchanges
sudo dpkg-reconfigure -plow unattended-upgrades

This enables security-only updates with automatic reboot disabled (safe default). Verify:

sudo unattended-upgrades --dry-run 2>&1 | head -10
cat /etc/apt/apt.conf.d/20auto-upgrades

Expected 20auto-upgrades content:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";

20.4 Clean Up Legacy Docker Network

After deploying with network segmentation, the old default network may remain:

# Check if orion_default still exists
docker network ls | grep orion_default

# Remove it (safe — no containers should be using it)
docker network rm orion_default 2>/dev/null || echo "Already removed"

20.5 Verification

# fail2ban jails active (should show sshd and caddy-auth)
sudo fail2ban-client status

# SSH jail details
sudo fail2ban-client status sshd

# Docker networks (should show 3: frontend, backend, monitoring)
docker network ls | grep orion

# Unattended upgrades configured
sudo unattended-upgrades --dry-run 2>&1 | head

# Caddy access log being written
sudo tail -1 /var/log/caddy/access.log

---

Step 21: Cloudflare Domain Proxy

Move DNS to Cloudflare for WAF, DDoS protection, and CDN. This step involves DNS propagation — do it during a maintenance window.

!!! warning "DNS changes affect all services" Moving nameservers involves propagation delay (minutes to hours). Plan for brief interruption. Do this step last, after Steps 19–20 are verified.

21.1 Pre-Migration: Record Email DNS

Before changing nameservers, document all email-related DNS records:

# Run for each domain (wizard.lu, omsflow.lu, rewardflow.lu)
dig wizard.lu MX +short
dig wizard.lu TXT +short
dig _dmarc.wizard.lu TXT +short
dig default._domainkey.wizard.lu TXT +short  # DKIM selector may vary

Save the output — you'll need to verify these exist after Cloudflare import.

21.2 Add Domains to Cloudflare

1. Log in to Cloudflare Dashboard
2. Add a site for each domain: wizard.lu, omsflow.lu, rewardflow.lu
3. Select Free plan → choose Full setup (nameserver-based, not CNAME/partial)
4. Block AI crawlers on all pages
5. Cloudflare auto-scans and imports existing DNS records — review carefully:
   • Delete any stale CNAME records (leftover from partial setup)
   • Add missing A/AAAA records manually (Cloudflare scan may miss some)
   • Verify MX/SPF/DKIM/DMARC records are present before changing NS
   • Email records (MX, TXT) must stay as DNS-only (grey cloud) — never proxy MX records
6. Set proxy status:
   • Orange cloud (proxied): @, www, api, flower, grafana — gets WAF + CDN
   • Grey cloud (DNS only): git — needs direct access for SSH on port 2222

21.3 Change Nameservers

At your domain registrar (Netim), update NS records to Cloudflare's assigned nameservers. Cloudflare shows the exact pair during activation (e.g., name1.ns.cloudflare.com, name2.ns.cloudflare.com).

Disable DNSSEC at the registrar before switching NS — re-enable later via Cloudflare.

21.4 Generate Origin Certificates

Cloudflare Origin Certificates (free, 15-year validity) avoid ACME challenge issues when traffic is proxied:

1. In Cloudflare: SSL/TLS > Origin Server > Create Certificate
2. Generate for each domain with specific subdomains (not wildcards):
   • wizard.lu: wizard.lu, api.wizard.lu, www.wizard.lu, flower.wizard.lu, grafana.wizard.lu
   • omsflow.lu: omsflow.lu, www.omsflow.lu
   • rewardflow.lu: rewardflow.lu, www.rewardflow.lu
3. Download the certificate and private key (private key is shown only once)

!!! warning "Do NOT use wildcard origin certs for wizard.lu" A *.wizard.lu wildcard cert will match git.wizard.lu, which needs a Let's Encrypt cert (DNS-only, not proxied through Cloudflare). Use specific subdomains instead.

Install on the server:

sudo mkdir -p /etc/caddy/certs/{wizard.lu,omsflow.lu,rewardflow.lu}

# For each domain, create cert.pem and key.pem:
sudo nano /etc/caddy/certs/wizard.lu/cert.pem    # paste certificate
sudo nano /etc/caddy/certs/wizard.lu/key.pem      # paste private key
# Repeat for omsflow.lu and rewardflow.lu

sudo chown -R caddy:caddy /etc/caddy/certs/
sudo chmod 600 /etc/caddy/certs/*/key.pem

21.5 Update Caddyfile

For Cloudflare-proxied domains, use explicit TLS with origin certs. Keep auto-HTTPS for git.wizard.lu (DNS-only, grey cloud):

{
    log {
        output file /var/log/caddy/access.log {
            roll_size 100MiB
            roll_keep 5
        }
        format json
    }
}

# ─── Platform 1: Main (wizard.lu) ───────────────────────────

    tls /etc/caddy/certs/wizard.lu/cert.pem /etc/caddy/certs/wizard.lu/key.pem
    reverse_proxy localhost:8001

21.6 Cloudflare Settings (per domain)

Configure these in the Cloudflare dashboard for each domain (wizard.lu, omsflow.lu, rewardflow.lu):

Setting	Location	Value
SSL mode	SSL/TLS > Overview	Full (Strict)
Always Use HTTPS	SSL/TLS > Edge Certificates	On
Bot Fight Mode	Security > Settings	On
DDoS protection	Security > Security rules > DDoS	Active (enabled by default)
AI crawlers	Security (during setup)	Blocked on all pages

Rate limiting rule (Security > Security rules > Create rule):

Field	Value
Match	URI Path contains /api/
Characteristics	IP
Rate	100 requests per 10 seconds
Action	Block
Duration	10 seconds

21.7 Production Environment

Add to ~/apps/orion/.env:

CLOUDFLARE_ENABLED=true

21.8 Verification

# CF proxy active (look for cf-ray header)
curl -I https://wizard.lu | grep cf-ray

# DNS resolves to Cloudflare IPs (not 91.99.65.229)
dig wizard.lu +short

# All domains responding
curl -I https://omsflow.lu
curl -I https://rewardflow.lu
curl -I https://api.wizard.lu/health

# git.wizard.lu still on Let's Encrypt (not CF)
curl -I https://git.wizard.lu

!!! info "git.wizard.lu stays DNS-only" The Gitea instance uses SSH on port 2222 for git operations. Cloudflare proxy only supports HTTP/HTTPS, so git.wizard.lu must remain as DNS-only (grey cloud) with Let's Encrypt auto-SSL via Caddy.

Step 22: Incident Response Runbook

A comprehensive incident response runbook is available at Incident Response. It includes:

• Severity levels: SEV-1 (platform down, <15min), SEV-2 (feature broken, <1h), SEV-3 (minor, <4h)
• Quick diagnosis decision tree: SSH → Docker → containers → Caddy → DNS
• 8 runbooks with copy-paste commands for common incidents
• Post-incident report template
• Monitoring URLs quick reference

---

Step 23: Environment Reference

A complete environment variables reference is available at Environment Variables. It documents all 55+ configuration variables from app/core/config.py, grouped by category with defaults and production requirements.

---

Step 24: Documentation Updates

This document has been updated with Steps 19–24. Additional documentation changes:

• docs/deployment/incident-response.md — new incident response runbook
• docs/deployment/environment.md — complete env var reference (was empty)
• docs/deployment/launch-readiness.md — updated with Feb 2026 infrastructure status
• mkdocs.yml — incident-response.md added to nav

Troubleshooting

Permission denied on logs

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

sudo chown -R 1000:1000 logs uploads exports

Celery workers restarting

Check logs for import errors:

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:

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:

git stash
git pull
git stash pop

Maintenance

Deploy updates

Deployments happen automatically when pushing to master (see Step 16). For manual deploys:

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

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

View logs

# 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

# 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

# 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
