I need to pass all video or audio or USB devices to a container.
devices:
- "/dev/video*:/dev/video*"
This apparently doesn't work. But I the platform the container runs on, could have 2, 3 or more video sources and I need to pass all these into the docker container.
Anyone an idea, how to make this possible with docker-compose? I don't want to use 'priviledged' mode.
Thanks! Martin
You can map /dev to container, and add cgroups permission for the device.
If directly use docker command, see this
docker run -it --rm -v /dev:/dev --device-cgroup-rule='c *:* rmw' ubuntu:18.04 /bin/bash
You can change the first * in above command to major device number if you want to limit to some devices.
For compose, it seems just 2.3 can support this(I'm not sure why 3 not support, maybe need times), see this
version: "2.3"
services:
backend:
image: ubuntu:18.04
device_cgroup_rules:
- 'c *:* rmw'
volumes:
- /dev:/dev
