If you want to use it for the purpose of learning it, please do use it.

Kubernetes as usual is a tool like others, you can't use one tool everywhere. Where bash scripts work, they just work, where they don't they fall apart too, kubernetes works like a charm.

Use your grug brains a little and choose wisely! In the end, who the hell cares if you use kubernetes or bash scripts to scale if your users are happy?

Well Said!
