Docker Swarm：restart-policy 不允许附加属性 restart-policy

Question

鉴于以下（为了论证而简化）docker-compose.yml文件：

version: '3'

services:
  postgres:
    image: fleetit-postgres
    deploy:
      restart-policy:
        condition: on-failure
    ports:
      - "5432:5432"
    environment:
      POSTGRES_USER: "root"
      POSTGRES_PASSWORD: "demo1234"
      POSTGRES_DB: "fleetit"

我试图用命令部署一个堆栈

docker stack deploy -c docker-compose.yml stackdemo

但它只是给我抛出了错误

restart-policy Additional property restart-policy is not allowed

我究竟做错了什么？

这是我正在运行的 Docker 版本：

Answer 1

你有一个错字。它应该restart_policy用下划线代替restart-policy。
