Docker container running AirNav RadarBox's rbfeeder. Designed to work in tandem with sdr-enthusiasts/readsb-protobuf. Builds and runs on x86_64, arm64 and arm32v7.
rbfeeder pulls ModeS/BEAST information from a host or container providing ModeS/BEAST data, and sends data to RadarBox.
For more information on what rbfeeder is, see here: sharing-data.
latest(mainbranch,Dockerfile)latest_nohealthcheckis the same as thelatestversion above. However, this version has the docker healthcheck removed. This is done for people running platforms (such as Nomad) that don't support manually disabling healthchecks, where healthchecks are not wanted.- Version and architecture specific tags available
Currently, this image should pull and run on the following architectures:
amd64: Linux x86-64arm32v7,armv7l: ARMv7 32-bit (Odroid HC1/HC2/XU4, RPi 2B/3B)arm64,aarch64: ARMv8 64-bit (RPi 4 64-bit OSes)
First-time users should obtain a RadarBox sharing key.
In order to obtain a RadarBox sharing key, on the first run of the container, rbfeeder will generate a sharing key and print this to the container log.
timeout 300s docker run \
--rm \
-it \
-e BEASTHOST=YOURBEASTHOST \
-e LAT=YOURLATITUDE \
-e LONG=YOURLONGITUDE \
-e ALT=YOURALTITUDE \
ghcr.io/sdr-enthusiasts/docker-radarbox:latestThis will run the container for five minutes, allowing a sharing key to be generated.
You should obviously replace YOURBEASTHOST, YOURLATITUDE, YOURLONGITUDE and YOURALTITUDE with appropriate values.
Shortly after the container launches, you should be presented with:
[2020-04-02 11:36:31] Empty sharing key. We will try to create a new one for you!
[2020-04-02 11:36:32] Your new key is g45643ab345af3c5d5g923a99ffc0de9. Please save this key for future use. You will have to know this key to link this receiver to your account in RadarBox24.com. This key is also saved in configuration file (/etc/rbfeeder.ini)
Take a note of the sharing key, as you'll need it when launching the container.
If you're not a first time user and are migrating from another installation, you can retrieve your sharing key using either of the following methods:
- SSH onto your existing receiver and run the command
rbfeeder --showkey --no-start - SSH onto your existing receiver and run the command
grep key= /etc/rbfeeder.ini
docker run \
-d \
--rm \
--name rbfeeder \
-e TZ="YOURTIMEZONE" \
-e BEASTHOST=YOURBEASTHOST \
-e LAT=YOURLATITUDE \
-e LONG=YOURLONGITUDE \
-e ALT=YOURALTITUDE \
-e SHARING_KEY=YOURSHARINGKEY \
ghcr.io/sdr-enthusiasts/docker-radarbox:latestYou should obviously replace YOURBEASTHOST, YOURLATITUDE, YOURLONGITUDE, YOURALTITUDE and YOURSHARINGKEY with appropriate values.
For example:
docker run \
-d \
--rm \
--name rbfeeder \
-e TZ="Australia/Perth" \
-e BEASTHOST=readsb \
-e LAT=-33.33333 \
-e LONG=111.11111 \
-e ALT=90 \
-e SHARING_KEY=g45643ab345af3c5d5g923a99ffc0de9 \

Before raising an issue regarding connection errors, please wait at least 10 minutes. The rbfeeder binary is configured to attempt to connect to a collection of servers in a round-robin method. It appears normal for some servers to reject the connection, so it may take several minutes to find an available server and connect. In the example below, it took approximately 6 minutes from container start to connection established.
You can try to solve this by setting this parameter:
- RB_SERVER=trueThis will enforce the use of a hardcoded IP address that is known to work (as of 22-Nov-2023). It will connect you to a European server if you are located in the Eastern Hemisphere (incl Asia/Oceania), or to a US based server if you are in the Americas.
You may also receive a spurious error Error authenticating Sharing-Key: Invalid sharing-key. Provided you have entered your sharing key correctly, just ignore this for several minutes.
Here is some example output with RBFeeder Version 1.0.10 (build 20231120150000) showing the aforementioned behaviour:

There are a series of available environment variables:
| Environment Variable | Purpose | Default |
|---|---|---|
BEASTHOST |
Required. IP/Hostname of a Mode-S/BEAST provider (dump1090/readsb) | readsb |
BEASTPORT |
Optional. TCP port number of Mode-S/BEAST provider (dump1090/readsb) | 30005 |
UAT_RECEIVER_HOST |
Optional. IP/Hostname of an external UAT decoded JSON provider (eg: dump978-fa). | |
UAT_RECEIVER_PORT |
Optional. TCP port number of the external UAT decoded JSON provider. | 30979 |
SHARING_KEY |
Required. Radarbox Sharing Key | |
LAT |
Required. Latitude of the antenna | |
LONG |
Required. Longitude of the antenna | |
ALT |
Required. Altitude in metres | |
TZ |
Optional. Your local timezone | GMT |
STATS_INTERVAL_MINUTES |
Optional. How often to print statistics, in minutes. | 5 |
VERBOSE_LOGGING |
Optional. Set to true for no filtering of rbfeeder logs. |
false |
DEBUG_LEVEL |
Optional. Set to any number between 0 and 8 to increase verbosity of rbfeeder logs. |
0 |
ENABLE_MLAT |
Option. Set to true to enable MLAT inside of the container. See MLAT note below |
true |
MLAT_RESULTS_BEASTHOST |
a hostname or IP, where MLAT results should be sent. (disables 30105 results listen port) | |
MLAT_RESULTS_BEASTPORT |
a port number, specify the TCP port number where MLAT results should be sent. | 30104 |
RB_SERVER |
Optional. If set to true, the container will attempt to connect to one of two Radarbox Servers that are known to work as of 22-Nov-2023. You can also explicitly set it to a hostname or IP address. If unset, the default settings of RadarBox will be used. |
Unset |
The following TCP ports are used by this container:
32088-rbfeederlistens on this port, however I can't find the use for this port...30105-mlat-clientlistens on this port to provide MLAT results. (mlat results listen port disabled whenMLAT_RESULTS_BEASTHOSTis set to work around rbfeeder bug)
You may find that MLAT in your container will often times spit out errors in your logs, such as
[rbfeeder] Disconnecting from mlat1.rb24.com:40900: No data (not even keepalives) received for 60 seconds
[rbfeeder] Connected to multilateration server at mlat1.rb24.com:40900, handshakingThis is likely, but not always, not caused by anything you are doing, but is instead caused by the Radarbox server itself and as such there isn't anything you can do to fix it. You will see in your Radarbox stats very little, if any, MLAT targets from your feeder while it is doing this.
To stop the feeder from spamming your logs you can set ENABLE_MLAT=false in your environment configuration for Radarbox and it will stop the MLAT service, and the log messages. Please note that if you do this, and you use MLAT Hub please remove Radarbox from your READSB_NET_CONNECTOR under MLAT Hub.
The container internally uses a binary called rbfeeder to send data to the RadarBox service. This binary is provided as closed-source by AirNav (the company that operates RadarBox) and is only available in armhf (32-bit) format using 4kb kernel pages. This will work well on Raspberry Pi 3B+, 4B, and other ARM-based systems that use either 32-bits or 64-bits Debian Linux with a 4kb kernel page size. It also works well on x86 Linux where we use the qemu ARM emulator to run the binary.
Debian Linux for Raspberry Pi 5 uses by default a kernel with 16kb page sizes, and this is not compatible with the rbfeeder binary. You will see failures in your container logs.
You can check your kernel page size with this command: getconf PAGE_SIZE . If the value returned is 4096, then all is good. If it is something else (for example 16384 for 16kb page size), you will need to implement the following work-around:
Add the following to /boot/firmware/config.txt (Debian 12 Bookworm or later) or /boot/config.txt (Debian 11 Bullseye or earlier) to use a kernel with page size of 4kb. This will make CPU use across your Raspberry Pi 5 slightly less efficient, but it will solve the issue for many software packages that have the same issue. After changing this, you must reboot your system for it to take effect:
kernel=kernel8.img
(a one-time command to add this would be:)
echo "kernel=kernel8.img" | sudo tee -a /boot/firmware/config.txt >/dev/null- All processes are logged to the container's stdout, and can be viewed with
docker logs [-f] container.
You can log an issue on the project's GitHub.
I also have a Discord channel, feel free to join and converse.
If you're getting continual segmentation faults inside this container, see: #16 (comment)
