Question

我有一个docker-compose.yml文件，其中包含以下内容：

version: "3"
services:
  mysql:
    image: "my-mysql:latest"
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: rootpw
  backend:
    image: "my-backend:latest"
    ports:
      - 19001:19001
      - 80:80
      - "9001:9000"
    environment:
      DB_USERNAME: test
      DB_PASSWORD: test
      DB_URL: jdbc:mysql://mysql:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&verifyServerCertificate=false&useSSL=true
      jdbc_url: jdbc:mysql://mysql:3306

    # command: dockerize -wait tcp://my-mysql:3306 -timeout 120s bin/playBinary
    links:
      - "mysql:mysql"

运行docker-compose up时 - 收到此错误：

如何在尝试启动第二个（后端）容器之前使第一个容器（MySQL）完全（100％）加载？

Answer 1

选项取决于

depend docker-compose

version: '3'
services:
  web:
    build: .
    depends_on:
      - db
      - redis
  redis:
    image: redis
  db:
    image: postgres
