Nextcloud Community and Collabora CODE in the same Docker network

Thank you for the guide. To bad it didn’t show up on my extensive research.

one point dragged my attention

So this means I need to configure a reverse proxy for the collabora container.

Or is it enough to set a domain name and assign a certificate?

If I need a reverse proxy, I’m not entirely sure how to properly set this up? I have an RP server running on the host, that has an RP for the NC container but also some other containers, I have configured.
A container in a bridge network can communicate with the host, if use proxy_pass. Does that mean, I have to set up an RP (nginx container) within the bridge network, that does the proxy_pass?

Or do I set up the RP within the bridge network to handle requests from NC container to Collabora container and the RP on the host handles requests from client to Collabora container?

Sorry if I overcomplicate something that may be trivial but none of the resources I have read, properly explains that topic. Or I don’t see how .
