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
The NATS Kubernetes operator is used here
- it seeds a CRD …
- … using which we can spawn a NATS cluster on Kubernetes (with a single command!)
- A
Service
object is created automatically – usesClusterIP
by default
The environment variable corresponding to the
Service
is used in the application logic to locate NATS server. Note its usage here
Cheers!
