I have setup an ubuntu 22.04 server on my proxmox host.

Installed docker and portainer on it.

Get to the portainer webgui.

Install / deploy a docker in this example - nginx proxy manager

Docker container installs and webgui is accessible.

Run through setup etc, add a proxy host confirm reverse proxy works.

If I reboot the host it loses all settings, how do I make it actually retain settings? Or what am I doing wrong? Is there some sort of setting I am just not seeing or or something?

​

This is my first time attempting to use portainer for anything.
