Hi,

i want to use this container as a proxy for our internal docker-registries that are, themselves, only reachable throw an HTTPS proxy. Can this container be used with such registries? If so, how should the container be configured to make it work?

I think I can answer my own question:

No, the proxy-module of nginx does not support http-proxies to connect to the upstream servers.

As a workaround, you can use socat to create a tunnel through the http-proxy and then use nginx to connect to the socat-port on localhost. Stackoverflow answer: https://stackoverflow.com/a/46824465
