Yes exactly is what you are thinking!! But there are some traps
Yes we can run xpenology on docker fully functional but inside a KVM VM but works pretty fine really.
Right now what I have is a simple docker that execute an instance of xpenology (clean, so the page of installation is shown to install)
I thinking which features do you think could be interesting for you?
give support to docker volumes inside the xpenology?
-v /myhost/data:/Volume1/myshare ?
Please
