uADSB are a series of minimally privileged docker containers for obtaining ADSB radio signals from airplanes via a SDR and sharing with various services.

• μreadsb
• μmlat
• μpa
• μpiaware
• μtar1090
• μ978

And while not part of the stack, you may also find these useful:

• plane-db-builder builds a customized list of planes to look out for with upa.
• polar.sh generates a graphic plot of planes from your feed.

To the extent that is practical, these Docker images attempt to provide functionality similar with the SDR Enthusiasts ultrafeeder, however are focused on minimizing the number of services and permissions required. All of the containers other than piaware and tar1090 are built on distroless nonroot. There is no init system in any container and a one process per container model is followed (as much as practical). All containers EXCEPT utar1090 run as user 65532 (Caddy needs permissions to manage tls certs but if you don't use that, you can run it as another user via a docker-compose setting).

With the assumption you're already running the sdr-enthusiasts stack, the build-docker-compose.sh included in this repository will build a template of a docker-compose.yml with similar settings provided you copy the .env file to the same directory to build. This stack doesn't utilize as many environmental variables in configuration, but you can directly configure the docker-compose.yml after the script builds it.

You'll also probably need to tinker with the Caddyfile to at a minimum, set the ip address of your device. It's set for a basic http, non-encrypted page but Caddy will support tls / http2 and http3 if tls is configured.

• 978 isn't tested at this point - there's tmpl file there but I don't have the dongle set up locally to confirm it works.
• Documentation is never enough.

Pull requests are welcome! But, you'd probably want to generate those either in the associated Dockerfile repository or into the upstream project (as readsb, mlat-client, etc are written and maintained by others).
