泊塢窗 - 撰寫錯誤

Question

這是我的搬運工，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 

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

而且在底部它說，這是可能是因爲泊塢窗，撰寫版本，但碼頭工人網站上說，窗戶上的碼頭工具與碼頭工作人員合成，不需要單獨安裝。

Answer 1

問題是您的web的縮進，請按照以下順序與databases服務相同。然後我管理運行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
