Dockerized Services with Caddy Reverse Proxy

This project provides a modular Docker setup for multiple services, all routed through a central Caddy reverse proxy with automatic HTTPS. Each service is managed independently in its own directory and connected via a shared Docker network.

Project Structure

/docker
  /caddy         # Caddy reverse proxy (entry point for all web traffic)
  /v2ray         # V2Ray VPN server (WebSocket over TLS)
  /draftly       # Draftly SPA frontend
  /openvpn       # OpenVPN server
  README.md

Shared Docker Network

All services that need to be accessible via Caddy are connected to a shared external Docker network called web. This allows Caddy to reverse proxy to any service by its Docker Compose service name.

---

1. Caddy (Reverse Proxy & TLS)

• Location: caddy/
• Purpose: Handles HTTPS, automatic certificate management, and reverse proxying for all domains/services.
• Config: Edit caddy/Caddyfile to add or update site blocks for each domain/service.
• Network: Connects to the shared web network.

Example Caddyfile blocks:

v2ray.ermolaev-frontend.ru {
  reverse_proxy v2ray:10000
  encode gzip
}

draftly.ermolaev-frontend.ru {
  reverse_proxy draftly:80
  encode gzip
}

Setup

cd caddy
# Start or restart Caddy
docker-compose up -d

---

2. V2Ray (VPN Server)

• Location: v2ray/
• Purpose: Provides a secure VPN server using the VMess protocol over WebSocket+TLS.
• Config: Edit v2ray/config.json to manage users (UUIDs) and settings.
• Network: Connects to the shared web network.

Setup

cd v2ray
docker-compose up -d

Client Configuration

• Address: v2ray.ermolaev-frontend.ru
• Port: 443
• UUID: YOUR_UUID_HERE
• Network: ws
• WebSocket Path: /v2ray
• TLS: enabled

---

3. Draftly (SPA Frontend)

• Location: draftly/
• Purpose: Runs the Draftly SPA frontend in a Docker container.
• Config: draftly/docker-compose.yml
• Network: Connects to the shared web network.

Setup

cd draftly
docker-compose up -d

• Accessible at: https://draftly.ermolaev-frontend.ru

---

4. OpenVPN (VPN Server)

• Location: openvpn/
• Purpose: Provides an OpenVPN server using the kylemanna/openvpn image.
• Config: openvpn/docker-compose.yml
• Network: (Optional) Add to web if you want to reverse proxy via Caddy.

Setup

cd openvpn
# Initialize config (run once):
docker volume create --name=ovpn_data
docker run -v ovpn_data:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://YOUR_SERVER_IP
docker run -v ovpn_data:/etc/openvpn --rm -it kylemanna/openvpn ovpn_initpki
# Start the server:
docker-compose up -d

---

Shared Network Setup

Create the shared network (once):

docker network create web

Ensure each service's docker-compose.yml includes:

networks:
  web:
    external: true

And the service is attached to the web network.

---

General Tips

• Caddy is your main entry point for all web traffic and HTTPS.
• Each service is managed independently.
• Add new services by connecting them to the web network and adding a Caddyfile block.
• Monitor containers with docker ps, docker stats, or logs.
