Here in the forum I posted a link to my git repository, how to make your Vero4 into to a small docker server. The problem is that if you use dockers own installer it ask the Vero4 which hardware platform and installs armhf, since it has both 32 & 64 bit support. What I did was to rewrite it to force 64bit arm server, which means it supports more modern containers. So the apt package, stops mediacenter and installs a bunch of console tools. Perfect for a headless miini-server, I’ve used this setup for more then 2 years, but I also know that it’s a system with limited memory and storage.
All this mentioned by fzinken earlier, in my mind mind it’s a good use of an older Mediabox.
