Traefik plugin download issue

README.md

CSP plugin download reproduction

So hey y'all

That's an adjusted version of traefik training repo

So I'm facing a problem that a plugin fails to download due to error 500. There's a similar error in GitHub

This script is a reproduction.

To reproduce:

  1. Clone all of the files
  2. Run docker stack deploy -c docker-compose.csp.yml traefik
  3. Once all is up, navigate to http://catapp.local
  4. You won't see the cats
  5. However, if you docker logs into the traefik container, it'll show an error that it failed to download the plugin

Any tips are appreciated
