Docker Supervisor Management Process

First, the use of supervisor to manage

Supervisor: Process management tool, based on C/s architecture. (It provides the Web interface to the user for querying and controlling), which allows the user to monitor and control the process of the Unix-like system.

Use supervisor to better control, manage, and restart the processes we want to run.

Here's a demonstration of how to use both SSH and Apache services. (Generate a new image via Docker BUiD)

Configuration

1. First create a dockerfile directory

Dockerfile File Contents

Supervisor Configuration File Contents

The first paragraph Supervsord configures the software itself and runs using the Nodaemon parameter. Nodaemon=true If the True,supervisord process is running in the foreground, the default is False, which is to run the daemon in the daemons.

The following 2 paragraphs contain the 2 services we want to control. Each section contains a directory of services and commands to start the service

The web and SSH services provided by the test Container

Second, Docker compose project

Compose project: From the previous Fig project, written in Python.

The Docker compose project is primarily used to orchestrate the deployment of Docker-based applications. It has a high degree of coordination with Docker/swarm.

Docker compose belongs to an "application tier" service.

Dockerfile enables users to manage a single application container, while compose allows the user to define a set of associated application containers (called a project) in a template (yml format). Docker-compose Service and Project description:

Service: That is, the application container.

Project: A complete business unit consisting of a set of associated application containers

Installing Docker-compose

Execute permissions on Docker-compose and move it to any path

After the installation is successful, you can view the version of Docker-compose and the usage of the command

Docker-compose command:

Test case

Below, we create a classic Web project: A haproxy that mounts three web containers.

The Docker-haproxy directory, which is the project working directory, in which you create two subdirectories: Haproxy and web.

#mkdir-P/root/docker-haproxy/{haproxy,web}

Write the Docker-compose.yml file (compose's main template file) in the/root/docker-haproxy/directory

Create the Haproxy Master profile in the/root/docker-haproxy/haproxy directory haproxy.cfg

To run the Compose project:

Execute Docker-compose up-d in the Docker-haproxy directory to launch your app
