When Kubernetes is not the right choice?
As with anything in the technology field, there is no one size fits all solution… And even kubernetes solving a big amount of problems you might have when exposing and scaling your application, it also brings some problems that you need to weight before deciding if this is the right technology for you or not….
Rails from “zero” to kubernetes – ingress reverse proxy
Following up on the ‘Rails from “zero” to kubernetes’ series, we’ll see today how to expose your service to the internet, since I think we all agree that mapping directly the port of your rails app to the internet is not a really wise choice.

How to create a request scope for your rails application
