libcamera-in-container

Demonstration on how to get libcamera working in a container

run demo

docker-compose up

![IMPORTANT] You may have to run the demo as root (or set up permissions), lest cam (in the container) won't have read access to the cameras!

clean up demo

docker-compose down

What's going on?

The build compiles libcamera by the books and installs dbus. This gives us the cam application, which can enumerate libcamera devices cam -l

Getting libcamera working in containers is just a matter of dabbling with dbus. To do this I gave the container full access to /run/udev. And voilà, libcamera works :)

Do note that you may have to set up permissions for your container (cam will say it has no r/w permission). Or you can just run the container as root.
