Docker - Nginx on a server running apache?

I would like to install and test out Bitwarden, see if it is a viable alternative for LastPass.

I am not familiar with Docker, and unless I am mistaken, the container installs a Nginx webserver?

The server I would like to install Bitwarden onto, already has a running Apache server (for my hompage, nextcloud, etc).

My best guess, is I would have to setup some reverse proxy to get this to work?

Any help tips, hints, guides, links would be greatly appreciated =)

Now that I think outloud, I have already more or less done this with Gitlab installation, which also uses Nginx. The difference is, it was without Docker.

So, would it work the same with Docker/Bitwarden?
