Add USB dongle to container using dockerd

Open Source Projects DockerEngine

My Docker environment is launched via a systemd service, whose relevant line is this:

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

This way of starting the docker daemon, however, does not expose USB dongles to the containerized application. Is there a way to tweak this command by adding a dockerd option that would do precisely that, namely add the USB dongle to the container?

If you want to use an usb device in a container, then it needs to be declared with --device when creating the container:

The compose file representation can be found here (without further explaination):

Note: this will not work with Docker Desktop
