Hostname for website running inside Docker

I'm new to docker and my question is similar to:

My websites running in docker containers, how to implement virtual host?

But I don't actually need to host multiple sites with different virtual hosts. I just need to get the server to respond to a particular virtual host name, eg: myhost.mysite.com

Right now the site works fine via IP but won't respond when I use the host name. Since I only have the one site/hostname do I have to setup a proxy as described in the question?

I've tried adding a -h 'myhost.mysite.com' to my docker run command but that didn't seem to make any difference.

PS. hostname DNS does correctly resolve to the IP address of the docker server.

That really depends on the web server running inside the container.

  • Apache: use ServerName and possibly ServerAlias
  • Nginx: use server_name
  • Django: use ALLOWED_HOSTS

Really, Docker doesn't need to know. The HTTP server software needs to know.

The question you linked to deals with multiple sites, which is why a proxy was needed. If you are only running one site, a proxy is not necessary (at least, not for this purpose). Just let Docker listen on port 80 and/or 443 itself, and let the server software running inside decide what hostname(s) are valid for the site.
