@ffs123 Great request! There are several Docker images available. Restreamer is built on Docker, and there are images for RaspberryPi and Odroid!
Works with OBS (Open Broadcast Studio).
I hope somebody gives this a try and lets us know how it goes!
On a somewhat related note, can anybody suggest a Cloudron host which is good value if you would like to stream a large quantity data each month?
