Services.traefik.ports.0 must be a string or number - docker-app.yml

So been reading up on the Penguins work, great stuff!
But when I get to the part where you’re supposed to setup traefik-app.yml, I get the error above.

$ docker stack deploy traefik-app -c traefik-app.yml
services.traefik.ports.0 must be a string or number

What can I do about this? It seems to be something about the ports section and well I am lost. :slight_smile:

I’m getting the same error. Did you get this solved?

'sup :fire::bread: :slight_smile:

This is probably a docker-compose version mismatch issue. What version are you using?

Yes, I found switching the yml to version: “3.2” corrected the issue. Now I’m having a different issue.

Well, at least that’s progress! :slight_smile: What’s the new issue?
