Docker compose configures MySQL and realizes remote connection

​

You need to ensure that your operating environment meets the following requirements ：

• Docker Engine
• Docker CLI
• Docker Compose

docker-compose.yml

version: '3.7'
services:
  mysql:
    image: "mysql/mysql-server:8.0"
    environment:
      TZ: "Asia/Shanghai"
      MYSQL_ROOT_PASSWORD: "123456" #  Set up root password 
      MYSQL_DATABASE: "library_manager" #  Set up the database 
      MYSQL_USER: "library_manager" #  The following items are connected Mysql When , Use this user name 
      MYSQL_PASSWORD: "123456"
    ports:
      - "33065:3306" #  mapping , If you need a remote connection Docker Database in , This is an important step 
    volumes:
      - mysql-data:/var/lib/mysql
      - ./.github/init.sql:/docker-entrypoint-initdb.d/init.sql
    restart: "always"
    container_name: "mysql"

The effect of remote connection is as follows ：

docker The configuration of the project in connecting to the database

environment:
      APP_ENV: "${APP_ENV:-prod}"
      DB_HOST: "mysql"
      DB_PORT: "3306" #  Because in the same environment , So just use 3306 Just port 
      DB_USERNAME: "library_manager"
      DB_PASSWORD: "password"
      DB_DATABASE: "database
