docker stack 无法连接到任何容器

我正在关注这使用教程这存储库。

并刚刚跑完docker stack deploy --compose-file docker-stack.yml vote。

我得到的输出表明容器正在运行：

cchilders:~/tutorials/docker/self-paced-training-beginner-linux-containers/example-voting-app (master) 
$ docker stack services vote
ID            NAME             MODE        REPLICAS  IMAGE
27yqy6x84gyk  vote_visualizer  replicated  1/1       manomarks/visualizer:latest
ism6o6nsn9or  vote_db          replicated  1/1       postgres:9.4
lcklesojqejm  vote_result      replicated  2/2       dockersamples/examplevotingapp_result:before
p0c6q08t8xpo  vote_worker      replicated  1/1       dockersamples/examplevotingapp_worker:latest
we85p3f2fx2z  vote_redis       replicated  2/2       redis:alpine
zv145asbefcu  vote_vote        replicated  2/2       dockersamples/examplevotingapp_vote:before

教程说你现在可以访问端口 5000、5001 等，但即使我的容器在堆栈中运行，它们也会全部失败。我得到

This site can’t be reached

localhost refused to connect.
Search Google for localhost 5001
ERR_CONNECTION_REFUSED

在 Chrome 中尝试以页面形式打开这些内容时，例如localhost:5000

他们建议您使用的文件是

version: "3"
services:

  redis:
    image: redis:alpine
    ports:
      - "6379"
    networks:
      - frontend
    deploy:
      replicas: 2
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure
  db:
    image: postgres:9.4
    volumes:
      - db-data:/var/lib/postgresql/data
    networks:
      - backend
    deploy:
      placement:
        constraints: [node.role == manager]
  vote:
    image: dockersamples/examplevotingapp_vote:before
    ports:
      - 5000:80
    networks:
      - frontend
    depends_on:
      - redis
    deploy:
      replicas: 2
      update_config:
        parallelism: 2
      restart_policy:
        condition: on-failure
  result:
    image: dockersamples/examplevotingapp_result:before
    ports:
      - 5001:80
    networks:
      - backend
    depends_on:
      - db
    deploy:
      replicas: 2
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure

  worker:
    image: dockersamples/examplevotingapp_worker
    networks:
      - frontend
      - backend
    deploy:
      mode: replicated
      replicas: 1
      labels: [APP=VOTING]
      restart_policy:
        condition: on-failure
        delay: 10s
        max_attempts: 3
        window: 120s

  visualizer:
    image: manomarks/visualizer
    ports:
      - "8080:8080"
    stop_grace_period: 1m30s
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"

networks:
  frontend:
  backend:

volumes:
  db-data:

唯一的步骤是

docker swarm init --advertise-addr $(docker-machine ip)
docker stack deploy --compose-file docker-stack.yml vote

从保存的example-voting-app目录中docker-stack.yml

为什么这些端口在服务正在运行时不会打开网页vote？谢谢

当主服务器被克隆并docker-compose up运行时result，无法构建容器：

当此容器无法运行时，端口 5000 将不会监听。

一个问题已经创建以解决这个问题。
