Docker-socket-proxy

I'm trying to tighten up the security on a pre-production build and have put in docker-socket-proxy.

I've managed to make it work by allowing access to all the api paths, but would like to start pulling out the ones traefik doesn't need.

Where can I find a list of API's that traefik requires access to? Someone mush have done this before I'd guess.

traefik.yml

version: '3.7'

docker-socket-proxy

This is where I've granted access to all the paths.

Hi @paulb

Doesn't look like it needs a lot from this issue comment

Edit:
An HAProxy comment later on:
