I was looking for a recent FROST-Server image to be deployed on a Raspberry Pi. Unfortunately I didn't find anything suitable on Docker-Hub, so I rolled my own.
You might want to use the included docker-compose.yaml file to fire up a FROST-Server
with a PostgreSQL/Postgis 11 instance on a Raspberry Pi. You only need to adjust the
serviceRootUrl option to point at the IP of your Pi.
