泊坞窗 - 撰写错误

Question

这是我的搬运工，compose.yaml

version: '2' 
services: 
    databases: 
    image: mysql 
    ports: 
    - "3306:3306" 
    environment: 
    - MYSQL_ROOT_PASSWORD=password 
    - MYSQL_USER=user 
    - MYSQL_PASSWORD=password 
    - MYSQL_DATABASE=demodb 
web: 
    image: nginx 

错误：The Compose file ./docker-compose.yml' is invalid because: Additional properties are not allowed('web' was unexpected)

而且在底部它说，这是可能是因为泊坞窗，撰写版本，但码头工人网站上说，窗户上的码头工具与码头工作人员合成，不需要单独安装。

Answer 1

问题是您的web的缩进，请按照以下顺序与databases服务相同。然后我管理运行docker-compose up

version: '2' 
services: 
    databases: 
    image: mysql 
    ports: 
     - "3306:3306" 
    environment: 
     - MYSQL_ROOT_PASSWORD=password 
     - MYSQL_USER=user 
     - MYSQL_PASSWORD=password 
     - MYSQL_DATABASE=demodb 
    web: 
    image: nginx
