What are the docker orchestration tools?

The docker orchestration tools are:

Two tools used with docker-------Supervisor and Compose. Let’s introduce these two tools and how to use them respectively.

1. Supervisor:

Use the process management tool supervisor to manage multiple processes in the container. Using Supervisor can better control, manage, and restart the processes we want to run. It is a c/s system.

Demonstration: Here we demonstrate how to use ssh and apache services at the same time.

First create a Dockerfile. The content and explanations of each part are as follows.

Create a dockerfile directory

The first paragraph supervsord configures the software itself and uses the nodaemon parameter to run. nodaemon=true If true, the supervisord process will run in the foreground. The default is false, which means it runs as a daemon process in the background.

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

Two: compose: orchestrate and deploy docker-based applications

Usage:

Install Docker-compose, We need to install pip first

Use wget to download: wget https://bootstrap.pypa.io/get-pip.py

Installation:

1.pip install docker -compose

2.ln -s /usr/bin/docker-compose /usr/local/bin/

3. After the installation is complete, you can use the dockercompose command.

We use the compose tool to experiment:

First, use Dockerfile or docker commit to define your application environment

Second, use a docker-compose.yml Define your application and they can be combined into separate containers to form your application.

The third step is to execute docker-composeup -d to start your application. It will pull/run related containers according to the settings of docker-compose.yml.

We use this diagram to represent the working directory structure of this project:

Docker-haproxy is the working directory of a project

Create two subdirectories in this directory, which are the two application directories we need.

Under docker-haproxy we also need a template file docker-compose.yml, which can create isolated containers.

Finally use docker-compose up -d to start the application.

Note: In these configuration files, we need to prepare the CD images to be used
