I trying to use multiple command at my container. If I just add plain CMD command at the end of Dockerfile, it’s will not working. The best way to use multiple command at Dockerfile is to use supervisord. Here the example:

  1. Create supervisor config file, in this example I have to running 2 command, 1 to serve reactjs app & 1 json-server to serve image from CDN.
Example Supervisor Config

Example Supervisor Config

  1. At the end of your Dockerfile, change it to CMD ["/usr/bin/supervisord"]. Don’t forget to expose your application port and add command to copy your supervisor config COPY spv.conf /etc/supervisor/conf.d/

  2. In the docker-compose just add other port services, in my case

ports:
    - '127.0.0.1:666:3000'
    - '127.0.0.1:999:3001'

That’s it, just run your dockerfile, hope it work well ;)
