I confirmed that on 3 different swarms. It works well with docker run cmd but not with docker service one.

Late response, but do you get a response by hitting http://0.0.0.0:8080? I ran into the same issue and think it may be related to this ipv6 issue with Swarm.

@eoli3n
Your browser seems to have chosen the IPv6 localhost.
And Docker Swarm still doesn't work with IPv6.
Try http://127.0.0.1:8080

[BretFisher]

Looks like this issue isn't related to this image. Indeed, on certain linux system "localhost" points to ::1 IPv6 so you'll need to point to 127.0.0.1. I'll close this issue for now.
