Docker or Ubuntu with HA

I was looking at ERPNext for a company that is starting out. I noticed that Docker is the recommended method of install, but was wondering how that would work with a starting inventory of couple hundred items to later couple thousand as they expand. Normally, I’d install Ubuntu for Linux stuff

Also was looking at advice for high availability. If Docker is the best option, I would assume docker swarm. If Ubuntu, then I wasn’t sure what the best option would be. I am not a Linux or docker person, but not afraid to try (I’m a windows server admin, but have dabbled in Linux and docker (using unraid))

Thanks for any advice!
