 Each node in the swarm will show all tasks running on it. When a service goes down it'll be removed. When a node goes down it won't, instead the circle at the top will turn red to indicate it went down. Tasks will be removed.

-If port 8080 is already in use on your host, you can specify e.g. `-p 5000:5000 -e HOST=[YOURHOST] -e PORT=5000` instead.
