docker-compose.yml運行時deny問題

在服務中加上 privileged: true
docker-compose.yml

version: '3'
services:
  mysql_1:
    image: mysql:5.7
    ports:
      - 3306:3306
    volumes:
      - "/data/mysql/node1/data/:/var/lib/mysql"
      - "/data/mysql/node1/conf.d/:/etc/mysql/conf.d"
    privileged: true
    environment:
      - MYSQL_ROOT_PASSWORD=123456
  mysql_2:
    image: mysql:5.7
    ports:
      - 3307:3307
    volumes:
      - "/data/mysql/node2/data:/var/lib/mysql"
      - "/data/mysql/node2/conf.d:/etc/mysql/conf.d"
    privileged: true
    environment:
      - MYSQL_ROOT_PASSWORD=123456
  mysql_3:
    image: mysql:5.7
    ports:
      - 3308:3308
    volumes:
      - "/data/mysql/node3/data:/var/lib/mysql"
      - "/data/mysql/node3/conf.d:/etc/mysql/conf.d"
    privileged: true
    environment:
      - MYSQL_ROOT_PASSWORD=123456

docker-compose 真方便
