If you are indie avoid it until you have 100 users and some revenue.

The last thing you want is to be fiddling with k8s when you have 3 whole users and $0 revenue.

Unless your niche strongly requires fancy architecture start with a $5 VPS and take it up from there.

You will never look back and think "shit if only I had used k8s on day one it wouldn't have failed".

More often it's closer to "shit if I had focused on non-tech stuff more maybe it would have gone somewhere ... instead I spent 2 months fiddling with YAML files".
