Difference from the Developer Onboarding Guide
This document is more of a step-by-step walk-through of getting the Casper pipeline set up and syncing between an eLMIS and a v3 system. It also gives a tutorial of how to create a new and add to a transformation in NiFi.
Determine Topology and Provision Resources
Lay out the topology for all of the pieces of the Casper architecture. For a developer with a powerful development machine, it is possible to run all of the pieces of the architecture on the same computer. However, a more likely configuration is to have at least two separate machines, generally dividing the major components equally; eLMIS and the pipeline for one, and v3 with the reporting stack for the other.
Stand up eLMIS
It is assumed there already exists a source system (i.e. eLMIS) deployed on a server. If not, a Gitlab repo (openlmis/casper-elmis) has been created to facilitate deploying an eLMIS server. It uses demo data from the Docker image openlmis/demo-data:casper, which is backed by the files here.
