Hi there! :)
I've just launched the new release of an open source embedded software named Luos.
Luos is like Docker, but dedicated to embedded systems. In other, words Luos is an open source architecture for designing, testing, and deploying embedded applications.
It could be great if you try it, and give me some feedback (I really need feedback) ➔ https://docs.luos.io
Of course I'm here if you need help :D
