MongoDB Kubernetes Deployment


While writing Tagging Asteroids with MongoDB I was able to quickly provision a cluster on the free tier of MongoDB Atlas. What I originally wanted was to quickly stand up a MongoDB instance in my Kubernetes environment but found most documentation too complex for my usecase.
