Stand alone NextCloudPi

I agree this is very strange uncommon but interesting requirement.

I think following discussions might be helpful for you

I think with lot of work you could achieve your goal if you

  • first build the local network with internet connection so you can follow normal installation path e.g. request certificates
  • setup split-brain DNS to access Nextcloud using local IP when inside of network (must be hosted on same Raspi)
  • isolate and host all “internal” network components like DNS, router, firewall etc on your Raspi (or something you carry withyou)
  • develop a procedure how to setup internet connection with DynDNS like service from time to time to refresh certificate (and perform updates)

I would call the project “local network to go” :wink:
