РЕПЛИКИ остается 0 после запуска `стек Docker deploy` команды в менеджер машине

Question

Я использую Docker для Mac и следить за этим tutorial

Все было прекрасно до этого section

после я запускаю эту команду

docker@manager:~$ docker stack services vote 

на результат показывает:

docker@manager:~$ docker stack services vote 
ID   NAME    MODE  REPLICAS IMAGE 
111ztgmjdwz1 vote_worker  replicated 0/1  dockersamples/examplevotingapp_worker:latest 
jqp0bcz1z22t vote_result  replicated 0/1  dockersamples/examplevotingapp_result:before 
m5bhkh9i8d9q vote_redis  replicated 0/2  redis:alpine 
nizvjk9eqrqv vote_db   replicated 0/1  postgres:9.4 
p83dn7dwxbey vote_visualizer replicated 0/1  dockersamples/visualizer:stable 
wd9wpxu34ooc vote_vote  replicated 0/2  dockersamples/examplevotingapp_vote:before 

Все REPLICAS: 0

Пожалуйста, помогите мне выяснить, в чем проблема.

UPDATE:

после того, как запустить команду stack ps, я получаю информацию ниже:

 
docker@manager:~$ docker stack ps vote

кажется докер не может загрузить изображение нормально, но я все еще могу получить docker run команду работы :

Answer 1

Возможно, у вас есть такая же проблема, как и я. Кажется, что порт 8080 уже занят, я узнал, что скайп взял его. Поэтому постарайтесь остановить Skype и подождать минутку.

После этого
