Hi,

Testing your traefik demo based on blog post:

If you need something else, let me know !

I'll also check why my 4th node is out.

And I have cluster lab 0.2.14

Even with my 4th node back on my picosluter, same resulta as we could expect.

@nsteinmetz I had a similar error message when I had a container on my cluster lab leader that occupied port 80. It seems not to make a difference if that container is running or not. Compose will complain until you remove that container.

@Govinda-Fichtner, you're right indeed. Funny or not, it was my previous image of traefik :-P

Thanks !
