Docker Registry Proxy

How to Set Up Your Own Docker Registry Proxy

To set up your own Docker Registry proxy, you can use the following `docker-compose.yml` configuration:

networks:
  proxy_network:
    ipam:
      config:
        - subnet: 10.20.30.0/24

services:
  registry:
    image: registry:latest
    container_name: hub-registry
    ports:
      - 5000:5000
    environment:
      REGISTRY_PROXY_REMOTEURL: https://registry-1.docker.io
    volumes:
      - ./data:/var/lib/registry
    networks:
      proxy_network:
        ipv4_address: 10.20.30.3

  nginx:
    image: nginx:latest
    container_name: internal-nginx
    ports:
      - 88:80
    volumes:
      - ./webroot:/usr/share/nginx/html
      - ./nginx.conf:/etc/nginx/conf.d/default.conf
    networks:
      proxy_network:
        ipv4_address: 10.20.30.4

  npm:
    image: 'jc21/nginx-proxy-manager:latest'
    container_name: npm
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
    networks:
      proxy_network:
        ipv4_address: 10.20.30.2

This configuration sets up a Docker Registry proxy with Nginx and Nginx Proxy Manager, all within a custom network. Follow these steps to start your proxy server:

1. Create the necessary directories for your configuration files.
2. Copy the above `docker-compose.yml` configuration into a file named `docker-compose.yml`.
3. Run `docker compose up -d` to start the services.
4. Configure your Docker clients to use the proxy as shown in the main instructions.
