Only Office installation guide for OMV5

Quote from uaytac

Is there a guide to install OnlyOffice for OMV 5?

Assuming you are talking about the online version, that is a fairly expensive product. I doubt anyone has written a guide to installing it on OMV.

No, I mean docker compose image (docker pull onlyoffice/documentserver).

That additional info was important. Why do you need a guide if you are just using a compose file? Just run it.

I would like to use onlyoffice with nextcloud. But I could not set letsencrypt with onlyoffice.

There are a few guides that have a proxy server container using lets encrypt that would sit in front of onlyoffice and nextcloud and let you use the cert.
