How to setup nginx as reverse proxy for rest microservice in kubernetes?

Question

I have a rest microservice and would like to setup nginx as a reverse proxy for it. I am little confused about which approach to follow:

1. Run nginx in each pod where application code is running.
2. Run nginx in separate pods and redirect http requests to application code running in separate pods.

Can someone explain which one is better

Answer 1

In my opinion, running nginx in a separate pod is a better option because that way you can scale up and down application separately from a proxy. Usually, we use one container with proxy and few with API.
