Hi nxtra,
Thanks for the help and useful info.
I will try this.
I try using Docker in Container Station on my Qnap NAS (https://www.qnap.com/solution/container_station/en-us/)
The only problem that i have, i found enough tutorials how install Docker on Win10, OSX and Linux, but not for a NAS. I don’t know how link a volume to a directory on my NAS :-/
