I am following this tutorial that uses this repository.
and have just run docker stack deploy --compose-file docker-stack.yml vote.
I get output that says the containers are running:
cchilders:~/tutorials/docker/self-paced-training-beginner-linux-containers/example-voting-app (master)
$ docker stack services vote
ID NAME MODE REPLICAS IMAGE

Tutorial says you can now hit ports 5000, 5001, etc, but even though my containers are running in the stack they all fail. I get
This site can’t be reached
localhost refused to connect.
Search Google for localhost 5001
ERR_CONNECTION_REFUSED
in Chrome when trying to open these as a page, like localhost:5000
The file they suggest you use is

The only steps were
docker swarm init --advertise-addr $(docker-machine ip)
docker stack deploy --compose-file docker-stack.yml vote
from the example-voting-app directory where the docker-stack.yml is held
Why don't these ports open a webpage if the service vote is running? Thank you
