尝试从入门教程开始使用docker-compose.yml.

version: "3"
   services:
     web:
       image: tuhina/friendlyhello:2.0
     deploy:
       replicas: 5
       resources:
         limits:
           cpus: "0.1"
           memory: 50M
      restart_policy:
        condition: on-failure
      ports:
        - "80:80"
      networks:
        - webnet
    networks:
      webnet:

得到此错误:

replicas Additional property replicas is not allowed

我输错了什么？

谢谢.
