> I have to learn 15 tools.

kubectl, kustomize, helm, istio, graphana, various flavors of ingress controllers, overlay networks, service meshes, storage controllers, etcd, etc.

you still have to learn 15 tools, just now they are hidden behind the scenes, and you still have to understand the underlying systems to reason about your containers.

this isn't for or against k8s - i'm a right tool for the job guy - but as a tool kubernetes doesn't solve problems, it encapsulates them and shifts them around.
