Question

我很困惑这里发生的事情，但是我将其范围缩小到一个很小的测试用例。这是我的docker-compose文件：

version: "3.7"
networks:
    cl_net_overlay:
        driver: overlay
services:
  redis:
    image: "redis:alpine"
    networks:
            - cl_net_overlay

cl_net_overlay网络不存在。当我使用以下命令运行该命令时：

docker-compose up

停顿一会儿，然后说：

WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

ERROR: for redis  Cannot start service redis: attaching to network failed, make sure your network options are correct and check manager logs: context deadline exceeded
ERROR: Encountered errors while bringing up the project.

在以前的笔记本电脑上，此文件对我来说运行良好。我的docker和docker-compose应该是最新的，因为这是一台全新的笔记本电脑。我缺少一些难题吗？

↪ docker --version

05:01:57::mlissner@gabbro::/tmp 
↪ docker-compose --version
docker-compose version 1.24.1, build 4667896b

有什么想法吗？我一直在努力使其整天都能正常工作，但我感觉有点迷失自我。

小跟进。消息说：

确保您的网络选项正确，并检查管理器日志

我不知道如何检查经理日志。那可能是有用的第一步？

根据评论进行另一跟进。如果我尝试部署它，我将没有日志，也无法启动：

另一个想法：以root身份运行。同样的问题。

您是否拥有正确的插件（请在docker info命令中查看更多信息）？

Plugins:
  Volume: local
  Network: bridge host ipvlan macvlan null overlay

它适用于：

$ docker swarm init
$ docker-compose up
WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

何时：

$ docker --version

和info：

无法与覆盖网络一起使用docker-compose
