Originally assigned to: @chr0nzz on GitHub.

I stumbled across your project on reddit, thinking that maybe I could give traefik a go with this after all (I'm using https://github.com/lucaslorentz/caddy-docker-proxy since years since traefik was way to complicated back when I looked at it ~ 5 years ago).

So envision a dummy user who doesn't have traefik installed already - what's the barebones traefik setup you need for traefik-manager to begin its supposed magic? I'm already lost when you mount /path/to/traefik/dynamic.yml:/app/config/dynamic.yml - I'm sure I can figure this out with enough time and research, but as I understand this project's value proposition, I actually should not have to dive into the traefik docs in order to manage it?

Just some honest first impression here, no criticism and maybe I don't understood the value proposition...

if you wanna test the installer script, run this

Ok, I gave it a spin, got stuck though. I have set it up to use http only for now.

I have 2 containers:

Thanks for testing this and reporting back - you found a real bug in the script.

The 502 was caused by the setup script telling Traefik to forward traffic to port 3000 on the manager container, but the container actually listens on port 5000. Traefik could reach the container but nothing was answering on that port, hence the bad gateway.

Also fixed a second issue in the same script where the CONFIG_DIR environment variable was being set to Traefik's internal config path instead of the manager's mounted path - this would have caused problems for anyone who chose the directory config layout.

Both are fixed in the latest version of the script. You can re-run it:

curl -fsSL https://raw.githubusercontent.com/chr0nzz/traefik-stack/main/setup.sh | bash
If you already have the stack running, just update the label in your docker-compose.yml at ~/traefik-stack/docker-compose.yml:

"traefik.http.services.traefik-manager.loadbalancer.server.port=5000"
Then run docker compose up -d traefik-manager to apply it.

Thanks, that works now and is a great help to start this from scratch.
