我正在使用 Docker for Mac 并遵循本教程
在本节之前一切都很好
在我运行这个命令之后
docker@manager:~$ docker stack services vote
结果显示：
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
所有 REPLICAS 为 0
请帮我找出问题所在。
更新：
运行stack ps命令后，我得到以下信息：

似乎docker无法正常下载图像，但我仍然可以获得docker run命令工作：
docker@manager:~$ docker run docker/whalesay cowsay hello
无法在本地找到图像 'docker/whalesay:latest'
