How to mount USB device to docker container in rootless mode
# How to mount RTL-SDR (Flightaware) USB dongle
# to docker container in rootless mode
#
# For example running: `docker run --device=/dev/bus/usb:/dev/bus/usb ...`
#
# or via docker compose:
#
# version: '3'
# services:
# dump1090:
# build: ./dump1090
# container_name: air_dump1090
# devices:
# - /dev/bus/usb:/dev/bus/usb
# ...
#
# STEP 1. List USB devices
lsusb -v
# STEP 2. Find your RTL SDR Device Descriptor
# For example:
#
# Device Descriptor:
# bLength 18
# bDescriptorType 1
# bcdUSB 2.00
# bDeviceClass 0
# bDeviceSubClass 0
# bDeviceProtocol 0
# bMaxPacketSize0 64
# THIS => idVendor 0x0bda Realtek Semiconductor Corp.
# THIS => idProduct 0x2832 RTL2832U DVB-T
# bcdDevice 1.00
# iManufacturer 1 Realtek
# iProduct 2 RTL2832U
# ...
#
# STEP 3. Replace idVendor and idProduct values in the command below (without "0x"):
# "0bda" and "2832" in my case
#
# STEP 4. Create udev rule in /etc/udev/rules.d/90-usb-rtlsdr.rules
sudo echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTR{idProduct}=="2832", MODE="0666"' > /etc/udev/rules.d/90-usb-rtlsdr.rules
# STEP 5. Reload rules via udev management tool
sudo udevadm control --reload-rules && sudo udevadm trigger
# STEP 6. Restart the container that uses the device
docker restart <my-dump1090-container>
# Have fun!
