Install and configure a containerized RTL Spyserver using Docker in your Raspberry Pi.

1. It's needed to block certain kernel modules to get the RTL-SDR device work properly. Place the blacklist-rtl.conf file into your host /lib/modprobe.d/ folder:

cp ./files/blacklist-rtl.conf /lib/modprobe.d/

2. Additionally, we need to set the correct permissions to the modules in order to allow TCP messages. Place the rtl_sdr.rules file into your host /etc/udev/rules.d/ folder:

cp ./files/rtl_sdr.rules /etc/udev/rules.d/

3. Reboot your Raspberry Pi, this action should only be done once.

4. Run the container using the docker-compose file included here:

version: "3.7"
services:
  spyserver:
    build: .
    ports:
     - "5555:5555"
    privileged: true
    volumes:
      - /dev/bus/usb:/dev/bus/usb

docker-compose up -d --build spyserver

5. The container will listen requests on 5555 port, connect to it using your RTL-SDR client (i.e. SDRSharp) and point to the IP of the Raspberry device.

sdr://<raspberry-ip>:55000

6. Enjoy it and open an issue or collaborate with a PR if anything is not working as expected.
