Technologies

• Docker
• Alpine Linux
• Node.JS
• Nginx
• pm2

The Setup

• Alpine Linux as the main OS
• Node.JS is listening from port 8081
• Nginx is configured as a Web Server and Reverse Proxy Server
  • Web Server
    • listen at port 8080
    • http://localhost:8080
  • Reverse Proxy Server
    • proxy all requests to /api/xxx
    • eg:
      • http://localhost/api/user/list
      • http://localhost/api/dashboard/list
• Mounted Folder
  • routes, models, *.js are mounted onto the container except for some other files/folders, see .dockerignore
• pm2 manages Node.JS server in watch mode. Changes to *.js files triggers a server restart

Commands

• $ docker-compose up # starts the container
• $ docker-compose up --build # rebuild the image
