You can build the container locally with
docker build -t ionmobilityviz:latest .
Note that the very first invocation will download the not-opensource and
not-redistributable libtimsdata.so. If you only use your docker image
locally, you could move this into the image build (NYI).
docker run --rm -it -p 3838:3838 ionmobilityviz:latest
Afterwards, you should see you shiny :-) visualisation at http://localhost:3838/IonMobilityViz/
