I. using Supervisor to manage processes

Docker The container opens a single process at startup, such as an SSH or Apache daemon service. However, we often need to open multiple services on a machine, this can be many ways, the simplest is to put a number of startup commands in a startup script, start the time to start the script directly .

Example: Docker run–d mirroring/run.sh

The installation process management tool is also installed.

This section uses the Process Management tool supervisor to manage multiple processes in the container. use Supervisor to better control, manage, and restart the processes we want to run .

Supervisor is a Process control system. It is a C/s system (Note: It provides a web interface to the user for querying and controlling), which allows the user to monitor and control the process of the Unix-like system.

Demonstrate how to use both SSH and Apache services.

1 first create a Dockerfile, and the contents and sections are explained below.

Summary: Dockersupervisor is similar to the previous dockerfile, where the difference is that Dockerfile uses a RUN.SH script-initiated application process, and Docker Supervisor application processes that are open using the Supervisor Process Management tool. Replaced the run.sh script file with the supervisor file.
