goreverse

Automatically detect running docker containers and redirect http traffic to them depending on the url.

I have a pi that runs pihole and other non-public services. I want to set nice names for these services in the pihole dns and just start docker containers. I guess jwilder/nginx-proxy does something similar, although I haven't really looked at it.

idea

• search all running containers for the tag goreverse and parse the value as a url
• get the public port that is mapped to private port 80
• proxy requests sent to the public port 80 of the machine to the private port of the matching container
• profit

notes

• the resolved url is set in the host header
• nginx
• reverse proxy already sets X-Forwarded-For
• Ealenn/Echo-Server is nice for manual testing: docker run --rm -p 80 -l goreverse=http://kek.com -d ealen/echo-server

todo

• accept https and terminate ssl
• listen on docker event channel and update on demand
• tests lul
