Docker

Installation

Prerequisites

The RTL DVB kernel modules must first be blacklisted on the Docker host. RTL-SDR itself is not required on the Docker host. This can be accomplished using the following commands:

echo 'blacklist dvb_usb_rtl28xxu' | sudo tee /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf
sudo rmmod dvb_usb_rtl28xxu

If the rmmod command errors, a reboot may will alternatively unload the driver.

Running the container

docker run -d --name radiosonde_auto_rx --restart="always" --device=/dev/bus/usb -v ~/radiosonde_auto_rx/station.cfg:/opt/auto_rx/station.cfg:ro -v ~/radiosonde_auto_rx/log/:/opt/auto_rx/log/ -p 5000:5000 ghcr.io/projecthorus/radiosonde_auto_rx:testing

Substitute ~/radiosonde_auto_rx/station.cfg and ~/radiosonde_auto_rx/log/ in the above command with the relevant local paths on your Docker host.

station.cfg should be configured as per Configuration-Settings. An example station.cfg can be found here.

Also ensure that an empty directory named log is available if you wish to retain log files.

--restart="always" will result in the container automatically restarting after a failure or host system reboot.

Once running, you can access the Web UI through http://<docker-host>:5000.

Docker Compose

If you wish to use Docker Compose instead of the docker CLI, the following basic docker-compose.yml can be used as a starting point:

services:
  radiosonde_auto_rx:
    container_name: radiosonde_auto_rx
    devices:
      - /dev/bus/usb
    image: ghcr.io/projecthorus/radiosonde_auto_rx:testing
    ports:
      - 5000:5000
    restart: always
    volumes:
      - ./station.cfg:/opt/auto_rx/station.cfg:ro
      - radiosonde_auto_rx_logs:/opt/auto_rx/log

volumes:
  radiosonde_auto_rx_logs:

station.cfg should be configured as per Configuration-Settings. An example station.cfg can be found here. The above path (./station.cfg) should be updated to reflect the location of station.cfg on your Docker host.

Other useful commands

Pulling the latest version of the container

docker pull ghcr.io/projecthorus/radiosonde_auto_rx:testing

You must then emove and recreate the container to use the newly pulled version.

Restarting the container

Restarting the container is useful for picking up changes to station.cfg.

docker restart radiosonde_auto_rx

Stoping the container

docker stop radiosonde_auto_rx

Removing the container

docker rm radiosonde_auto_rx
