当绑定文件时，卷必须是映射而不是字符串。

Question

目前，我正在尝试将两个文件绑定在一起，我已经检查了其他问题，但找不到答案。我甚至将这段代码粘贴到http://www.yamllint.com/中，它告诉我这是有效的YAML。我尝试过将nginx_config/nginx.conf.template:/etc/nginx/templates/nginx.conf.templates放在底部，但是yamllint位置从底部排在第二位(不知道这有什么区别)。这里到底出了什么问题？

volumes:
  couchdb3_data:
    driver: local
  minio_data:
    driver: local
  nginx_config/nginx.conf.template: /etc/nginx/templates/nginx.conf.templates
  redis_data:
    driver: local

我试着把这行放在“服务”部分下，但它并没有告诉我：service 'volumes' must be a mapping not an array

Answer 1

对于您要做的事情--绑定--将一个文件装入容器--您需要在特定服务的volumes部分中指定它。因此，例如，如果您想将文件./nginx_config/nginx.conf.template挂载到名为nginx的服务中，可以编写如下内容：

services:
  nginx:
    image: docker.io/nginx:mainline
    volumes:
      - ./nginx_config/nginx.conf.template:/etc/nginx/templates/nginx.conf.templates

您已经在docker-compose.yaml文件中的其他服务中使用了正确的语法(例如，您正在绑定的位置--在watchtower-service服务中挂载停靠套接字)。这和使用文件而不是套接字是一样的。
