This repo and Dockerfile replaces the OpenTripPlanner-data-container building process.
Using the mfdz opentripplanner docker image, all the neccessary building steps (aquiring gtfs, osm pbf and build/router config) happen as Dockerfile commands. This allows us to leverage dockers build caching as well as simpler building by calling docker build ..
The Dockerfile contains a multi-stage build, so the big otp and buildfile dependencies are only used for building, the resulting container is a small nginx:alpine based one that only delivers the build result as .zip.
