Question

我应用了docker教程来建立一个集群。我使用了docker工具箱，因为我使用的是Windows 10系列。

我执行所有语句，但是最后，语句“ curl ip_adress”没有运行。网址访问也出错。

$ docker --version
Docker version 18.03.0-ce, build 0520e24302

docker-compose.yml，位于名为“ myvm1”的虚拟机的/ home / docker中：

version: "3"
services:
  web:
    # replace username/repo:tag with your name and image details
    image: 12081981/friendlyhello:part1
    deploy:
      replicas: 5
      resources:
        limits:
          cpus: "0.1"
          memory: 50M
      restart_policy:
        condition: on-failure
    ports:
      - "80:80"
    networks:
      - webnet
networks:
  webnet:

群体：

$ docker-machine ssh myvm1 "docker stack ps getstartedlab"
ID                  NAME                  IMAGE                          NODE                DESIRED STATE       CURRENT STATE           ERROR               PORTS

“ docker-machine ls”的结果：

    NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER     ERRORS
default   -        virtualbox   Running   tcp://192.168.99.100:2376           v18.09.0
myvm1     *        virtualbox   Running   tcp://192.168.99.102:2376           v18.09.0
myvm3     -        virtualbox   Running   tcp://192.168.99.103:2376           v18.09.0

卷曲测试

$ curl 192.168.99.102
curl: (7) Failed to connect to 192.168.99.102 port 80: Connection refused

我该如何调试？

如果您愿意，我可以提供更多信息。

谢谢。

在Windows中使用路由网格现在似乎只是EE功能。您可以监视this docker for windows issue以获得更多详细信息。当前的解决方法是在内部使用DNSRR并将端口直接发布到主机，而不是通过路由网格发布。如果您希望从群集中的任何节点都可以访问应用程序，则意味着您需要在群集中的所有主机上都有一项服务，该服务是全局调度的，侦听请求的端口。例如

version: "3.2"
services:
  web:
    # replace username/repo:tag with your name and image details
    image: 12081981/friendlyhello:part1
    deploy:
      # global runs 1 on every node, instead of the replicated variant
      mode: global
      # DNSRR skips the VIP normally assigned to services
      endpoint_mode: dnsrr
      resources:
        limits:
          cpus: "0.1"
          memory: 50M
      restart_policy:
        condition: on-failure
    ports:
      - target: 80
        published: 80
        protocol: tcp
        # host publishes the port directly from the container without the routing mesh
        mode: host
