That's because you're not thinking web^Wcloud scale. To execute some code in response to event you need:

- several workers that will poll the source bucket for changes (of course you could've used existing notification mechanism like aws eventBridge, but that will couple you k8s to vendor-specific infra, so it kinda deminishes the point of k8s)

- distributed message bus with persistanse layer. Kafka will work nicely because they say so on Medium, even though it's not designed for this use case

- a bunch of stateless consumers for the events

- don't forget that you'll need to write processing code with concurrency in mind because you're actually executing it in truly destributed system at this point and you've made a poor choice for your messaging system

Wait, I can do all these with s3 and lambda at any scale - for pennies :) Will probably take few hours to set everything up with tools like stackery.io

So once again, why developers need kubernetes for? If the most simple problem becomes a habitholy mess :)
