Ah! I started with Yunohost too (and actually still have it on a Pi), definitely opened the port for all this in a nice way!
I agree with you on Docker, it can get complicate but the basics are very very easy. I would probably go with DockGe, I tried both before but didn't like much portainer :)
But thanks for both comments :)
Yup I read about the folder thing but got stung by it as well ahah
Thank for taking the time to explain, I am almost done with the transition of all my services and I did exactly like you suggested and everything works perfecty! :)
