Accessing Bluetooth dongle from inside Docker?

Question

Is it possible to use a bluetooth (BLE in my case) dongle inside of a docker container?

On my host machine:

$ hcitool dev
    Devices:
       hci0   5C:F

I can confirm that what OlivierM wrote is working on me. Spent some time on Raspberry Pi 3B+ and its built-in bluetooth.

Dockerfile:

FROM python:3.7

RUN apt-get update

RUN apt-get install -y bluez bluetooth

ENTRYPOINT sh docker_entrypoint.sh

and entrypoint:

#!/bin/bash

service dbus start
bluetoothd &

/bin/bash

sudo killall -9 bluetoothd is needed on host machine before before starting the container:

docker run --rm --net=host --privileged -it myimage:mytag
