当我运行docker stack deploy-c docker-stack.yml myapp时

我收到错误消息：

不允许使用db migrator附加属性db migrator

docker-stack.yml：

db migrator应处于服务下

您使用的是YAML文件，结构在这里很重要

version: "3"

services:
  web:
    image: tenzan/myapp_web:prod
    ports:
      - "80:3000"
    env_file:
      - .env/production/database
      - .env/production/web

  redis:
    image: redis

  database:
    image: postgres
    env_file:
      - .env/production/database
    volumes:
      - db_data:/var/lib/postgresql/data

  db-migrator:
    image: tenzan/myapp_web:prod
    command: ["./wait-for", "--timeout=300", "database:5432", "--", "bin/rails", "db:migrate"]
    env_file:
      - .env/production/database 
      - .env/production/web
    deploy:
      restart_policy:
        condition: none
