Docker-compose project is the official open source project of Docker, which is responsible for the rapid choreography of Docker container clusters. The default docker-compose configuration file is docker-comemage. yml. This article will explain the configuration in the file and provide common container configuration, such as: Mysql, Redis, MongoDB, rabbitMQ and other containers configuration.

Docker – compose the installation

  • Method 1: Install using the PIP

If you have a Python PIP environment on your system, you can install it directly with the following command.

pip install docker-compose
# or
pip3 install docker-compose
Copy the code

  • Method 2: Download the installation file

    GitHub:github.com/docker/comp…

    The curl -l https://github.com/docker/compose/releases/download/1.28.0/docker-compose- ` ` uname - s - ` uname -m ` -o/usr /local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
Copy the code

    In Linux, the uname command displays information about the PC and operating system. Uname -s Displays the operating system name. Uname -m Displays the computer type.

After the installation, check whether the installation is successful

docker-compose --version
Copy the code

Version Description The installation is successful. If the installation encountered problems can leave a message to contact me.

    # Resolve container dependencies, startup priorities. In the following example, other services are started before mysql is started

      - Other services
    You can link to other services

    # no, the default policy, does not restart the container when it exits
    # on-failure, restart container only if container exits abnormally (exit status non-zero)
    # on-failure:3, restart the container up to 3 times if the container exits abnormally
    Always, always restart the container when it exits
    # unless-stopped, the container is always restarted when the container exits, but does not consider containers that were stopped when the Docker daemon started
    restart: on-failure:3
    # execute command
    command: Commands to be executed
    
# Customize network group configuration

Common configuration instructions are the above, others can see the official website documents.

Docker-compose common command

Docker-compose up docker-compose up -d docker-compose up docker-compose up -d docker-compose up Docker-compose. Yml up -d # specifies the docker-compose template to stop and delete containers, networks, volumes, and images. Docker-compose logs docker-compose pull # check configuration dokcer-compose config -q # Docker-compose restart docker-compose start docker-compose stop docker-compose stopCopy the code

Common container configuration files

Mysql

version: '3'

services:
  # mysql service
  mysql:
    image: Mysql: 8.0.16

    container_name: mysql8
    # hostname
    hostname: mysql8
    # Environment variables
    environment:

      TZ: Asia/Shanghai
    # Mapping port
    ports:
      - 3306: 3306
    The MySQL data directory is mounted in the
    volumes:
      - ./data:/var/lib/mysql
