Bind specific ipv4 and ipv6 address

Installation
1

Is it possible to bind both the ipv4 and ipv6 address to the docker container that is generated from app.yml? My issue is that I have 2 ipv4 addresses and 2 ipv6 addresses.

I want to use 1st pair of addresses to run my main site from an apache server. I want to use the 2nd pair for discourse.

It looks like it is failing due to this issue:
Error starting userland proxy: listen tcp4 0.0.0.0:443: bind: address already in use.

I bet you have configured your proxies right, and I shouldn’t answer at all because I don’t know, but

  • is something else than Discourse/Docker listen 443
  • should you use real IP instead 0.0.0.0
