Specify in the Dockerfile that you need to install the supervisor, write your config for it, run as many services as you like through it. In general, the docker philosophy is 1 container - 1 process. The container lives while the process lives. When starting a container, only 1 process can be started.
Those. supervicor will be the process that keeps the container from finishing. And all other processes are controlled by the supervisor.
