Collabora server on remote machine?

I’m running Nextcloud inside Docker on an OMV RockPro64 system. I would really like to use Collabora to edit files from within Nextcloud. The problem is that the collabora/code docker repo does not support arm machines.

I was thinking of a workaround. What if I get myself a VPS and put Collabora on there, and then connect this remote Collabora server to my local system?

I know… As if it wasn’t enough of a big hassle to get Collabora running. But I was wondering if this is a feasible option? What do I need to keep in mind? How would I connect the local docker container to the remote docker container?

I hope this would be possible and people can give me tips, as I am not very experienced in all this.

All the best,
