docker stack 不會連接到任何容器

我正在關注使用此儲存庫的本教程。

並且剛剛執行docker stack deploy --compose-file docker-stack.yml vote。

我得到的輸出表明容器正在執行：

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

教程說您現在可以訪問埠 5000、5001 等，但即使我的容器在堆棧中執行，它們也會失敗。我明白了

This site can’t be reached

localhost refused to connect.
Search Google for localhost 5001
ERR_CONNECTION_REFUSED

在 Chrome 中嘗試將這些作為頁面打開時，例如localhost:5000

他們建議您使用的文件是

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:

唯一的步驟是

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

從保存的example-voting-app目錄docker-stack.yml

如果服務正在執行，為什麼這些埠不打開網頁vote？謝謝

當 master 被複製並docker-compose up執行時，result無法建構容器：

當此容器無法執行時，埠 5000 將不會偵聽。

已創建一個問題來解決此問題。
