Damn, same, nuked Traefik when v2 broke the setup I spent hours trying to figure out. I don’t think the concepts are overwhelming, but something is profoundly wrong with their documentation habits. Now someone in the comments here is saying v3 changes the way paths are read with regex? Lol, fuck Traefik, never again.

Alpine uses musl, and at least some amount of stuff has (implicit) hard dependencies with glibc. You might be running into that as well.
