Note that we have to delete the Mongo volume for the inidtb script to take effect. Else, it will not execute. To be used only for testing right now. Will figure out a more robust solution later.
Also using Google's JIB Maven plugin to reduce our Docker image footprint. Will make container upload and download much faster
