docker - 撰写错误

Question

这是我的docker-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)

在底部，它说这可能是因为docker-compose版本，但是在docker网站上它说窗户上的docker带有docker-compose而且不需要单独安装。 / p>

Answer 1

问题是web的缩进，请将其与databases服务的级别对齐，如下所示。然后我设法运行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
