I'm doing a similar setup, one docker will be navezgane and one docker will be randomgen.
My host is a surplus Dell R720 with 12cores/24threads, 64gb mem. I am consolidating all of my pet projects to one host, 7days docker is a big one as I had a linux box just for it. Does not seem to be very popular, also surprised to see it here. Been lurking threads and learning as I go since joining unRAID.
