NextcloudPi Docker/Testing Image for Odroid HC2

Hi there,

I tried to sort out the most recent docker image for a fresh install of NextcloudPi on an Odroid HC2 and found this:

https://hub.docker.com/u/ownyourbits/

But which of those docker images is for the HC2? Is it "ownyourbits/debian-ncp-arm64
"?

Another question, the download page (https://ownyourbits.com/downloads/) for the images offers a “testing” directory. Are these experimental images or kind of safe to install?

Best
