NATS on Kubernetes example

In a previous blog, you saw an example of NATS along with producer and consumer – based on Docker Compose. This post uses the same app, but runs on Kubernetes

For how to run, follow the README on Github

High level overview

• uses the NATS Kubernetes operator
  • it seeds a CRD …
  • … using which we can spawn a NATS cluster on Kubernetes (with a single command!)
  • A Service object is created automatically – uses ClusterIP by default

NATS Kubernetes Service object

• The environment variable corresponding to the Serviceis used in the application logic to locate NATS server. Note its usage here

Cheers!
