Why is Kubernetes getting so popular?
It has most of the features needed.Everyone was trying to make a system simple and adopted, but if you want it to be adopted, it's going to need a lot of features. Also Google worked some real magic in getting Kubernetes being supported by all the cloud providers.It's a framework that will enable you to do what you want, while being the standard.You could write your script to do that in a simpler way, but most people already know the standard and it's easier for everybody to understand Kubernetes rather than your clever solution.
