Hello there,

first of all hi!  
This is my first post here and I hope I make it right. I tried to fix this odd issue now for more than 3h and nothing, I searched online and even here. I found people that had the same problem and I tried the fix people provided, but still nothing.

So maybe someone can help me here.

In swarm mode, the labels must be placed inside the `deploy` section.
