Meshing Legacy Systems with Habitat Deployed Components to...

" summary

Built a three-tier IRC-like app (RethinkDB, Go API, nginx front end with React/webpack/yarn) and migrates it using Habitat by using a small number of changes and infrastructure pieces. Demonstrates a lightweight, no-op package that holds legacy connection info so Habitat services bind to it, a service proxy for one-way access, and a console DNS bridge to enable bi-directional discovery. Migration works in practice; took about two weeks to assemble and test.
