시스템 구성

docker-compose.yml

version: "3.7"

services:
  db:
    image: mysql:5.7
    volumes:
      - ./db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress_user
      MYSQL_PASSWORD: 123456
  
  app:
    depends_on: 
      - db
    image: wordpress:latest
    volumes:
      - ./app_data:/var/www/html
    ports:
      - "8080:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_NAME: wordpress
      WORDPRESS_DB_USER: wordpress_user
      WORDPRESS_DB_PASSWORD: 123456 

docker-compose를 사용하면 network를 따로 생성할 필요가 없다!!

command

docker network create wordpress_net


docker \
run \
    --name "db" \
    -v "$(pwd)/db_data:/var/lib/mysql" \
    -e "MYSQL_ROOT_PASSWORD=123456" \
    -e "MYSQL_DATABASE=wordpress" \
    -e "MYSQL_USER=wordpress_user" \
    -e "MYSQL_PASSWORD=123456" \
    --network wordpress_net \
mysql:5.7

docker \
    run \
    --name app \
    -v "$(pwd)/app_data:/var/www/html" \
    -e "WORDPRESS_DB_HOST=db" \
    -e "WORDPRESS_DB_USER=wordpress_user" \
    -e "WORDPRESS_DB_NAME=wordpress" \
    -e "WORDPRESS_DB_PASSWORD=123456" \
    -e "WORDPRESS_DEBUG=1" \
    -p 8080:80 \
    --network wordpress_net \
wordpress:latest

wordpress_net 라는 네트워크를 따로 생성하고 각 컨테이너에 연결시켜줘야 한다.

docker-compose : spring boot + mysql
