TLS forwarding to real localhost

[MeganerdNL]

I'm swicthing to dnscrypt-server from normal operation to docker.
The machine I'm running the docker image on runs nginx and doh-proxy on it too.

nginx is running on port 8443 so that dnscrypt-server can run on 443.
nginx reverse-proxys to doh-proxy and serves a web-page.

That worked fine when I was running dnscrypt-proxy wirthout docker.
When starting teh docker image with

docker run --name=dnscrypt-server -p 443:443/udp -p 443:443/tcp -p 9100:9100/tcp \ --restart=unless-stopped \ -v /etc/dnscrypt-server/keys:/opt/encrypted-dns/etc/keys \ jedisct1/dnscrypt-server init -N myname.org -A -M 0.0.0.0:9100 -T 127.0.0.1:8443 \ -E '133.224.17.124:443,[2001:14f0:5001:bbb:5300:030f:fee7:f70d]:443'

it obviously doesn't work because 127.0.0.1 revers to the internal address of the docker container, but it should refer to localhost of my machine where nginx resides.

How to accomplish that in a safe way? I managed to get it to work with adding --network=host to the docker command. Is that safe and the only way?

I went with --network=host and strict firewall. Read a lot about it and it seems the best. Now I can query unbound inside the container too. Sorry to bother you :)

This is great!

Sorry, I'm not too familiar with Docker either...
