-# Deployment Guide
-
-This guide covers deploying GcIndexRelay on a VPS using Docker Compose.
-
-## Architecture
-
-```
-Host reverse proxy (port 80/443) → localhost:4000
-    ↓
-Phoenix container (app) — published port 4000:4000
-    ↓ (internal Docker network only)
-AGE/Postgres container (db) — no published ports, volume: pgdata
-```
-
-TLS is terminated by the host-level reverse proxy. The Phoenix app runs behind
-it and trusts the `X-Forwarded-Proto` header to enforce HTTPS.
-
-## Prerequisites
-
-- A VPS running Debian/Ubuntu
-- Docker and Docker Compose installed
-- A domain name pointed at your VPS
-
-## 1. Install Docker and Docker Compose
-
-```bash
-curl -fsSL https://get.docker.com | sh
-sudo usermod -aG docker $USER
-# Log out and back in for group membership to take effect
-```
-
-Verify: `docker compose version`
-
-## 2. Clone the Repository
-
-```bash
-git clone <repo-url> /opt/gc_index_relay
-cd /opt/gc_index_relay
-```
-
-## 3. Configure Secrets
-
-Copy the example file and fill in your values:
-
-```bash
-cp .env.example .env
-$EDITOR .env
-```
-
-Required values to set in `.env`:
-
-- **`POSTGRES_PASSWORD`** — use a strong random password
-- **`SECRET_KEY_BASE`** — generate with:
-  ```bash
-  docker run --rm hexpm/elixir:1.17.3-erlang-27.3.4.7-debian-trixie-20260202-slim \
-    mix phx.gen.secret
-  # or without Docker:
-  openssl rand -base64 64
-  ```
-- **`PHX_HOST`** — your actual domain name (e.g. `relay.example.com`)
-
-## 4. Set Up the Reverse Proxy
-
-The app listens on `localhost:4000`. Configure nginx or Caddy to forward
-traffic and terminate TLS.
-
-### Caddy (recommended)
-
-```caddy
-relay.example.com {
-    reverse_proxy localhost:4000
-}
-```
-
-### nginx
-
-```nginx
-server {
-    listen 443 ssl;
-    server_name relay.example.com;
-
-    ssl_certificate /etc/letsencrypt/live/relay.example.com/fullchain.pem;
-    ssl_certificate_key /etc/letsencrypt/live/relay.example.com/privkey.pem;
-
-    location / {
-        proxy_pass http://localhost:4000;
-        proxy_set_header Host $host;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-}
-```
-
-## 5. Configure Firewall
-
-Expose only SSH, HTTP, and HTTPS to the public internet:
-
-```bash
-sudo ufw allow 22/tcp
-sudo ufw allow 80/tcp
-sudo ufw allow 443/tcp
-sudo ufw enable
-```
-
-The database port (5432) must **not** be exposed — it is on an internal Docker
-network only and never published to the host.
-
-## 6. Build and Start the Stack
-
-```bash
-docker compose build
-docker compose up -d
-```
-
-On first start, the app container will:
-1. Wait for the database to pass its health check
-2. Run any pending Ecto migrations
-3. Start the Phoenix server
-
-## 7. Verify the Deployment
-
-```bash
-# Check container status
-docker compose ps
-
-# Health check endpoint
-curl http://localhost:4000/health
-# Expected: 200 OK, body: "ok"
-
-# API endpoint
-curl http://localhost:4000/api/events
-# Expected: JSON response
-
-# Confirm database port is NOT accessible from host
-curl http://localhost:5432
-# Expected: connection refused
-```
-
-## Operations
-
-### View logs
-
-```bash
-docker compose logs -f app
-docker compose logs -f db
-```
-
-### Restart the app
-
-```bash
-docker compose restart app
-```
-
-### Stop everything
-
-```bash
-docker compose down
-```
-
-Database data is persisted in the `pgdata` Docker volume and survives
-`docker compose down`. To also delete the data:
-
-```bash
-docker compose down -v
-```
-
-### Update to a new version
-
-```bash
-git pull
-docker compose build
-docker compose up -d
-```
-
-Migrations run automatically on startup.
