containered-pi-webcam

This container will run on a raspberry pi 3 b device with native camera enabled. It will capture a live video and present it via webrtc on a basic website.

usage

starting the container

docker run --rm \
--device /dev/video0 \
--volume /opt/vc:/opt/vc \
--user $(id -u):$(id -g) \
--port 8080:80 \
container_pi_webcam

Afterwards, you can access the webcam on port 8080 of the host.

Breakdown

Partially stolen from https://www.losant.com/blog/how-to-access-the-raspberry-pi-camera-in-docker.

• --device /dev/video0 -> passthrough camera device
• --volume /opt/vc:/opt/vc -> camera dependencies
• --env LD_LIBRARY_PATH=/opt/vc/lib -> set dependencies-libs path as env var
• --user $(id -u):$(id -g) -> set user to current user, because pi is a member of the video group and has thereby access to the device
• --port 8080:80 -> Forward external host port to container
