As Michelle Noorali put it in her keynote address at KubeCon Europe in March of this year: the Kubernetesopen source container orchestration engine is still hard for developers.

In reality, however, they still rely on operations in many aspects, which (understandably) dampens their enthusiasm about the disruptive potential of these technologies.
One major downside for developers is that Kubernetes is not able to auto-manage and auto-scale its own machines. As a consequence, operations must get involved every time a worker node is deployed or deleted. Obviously, there are many node deployment solutions, including Terraform, Chef or Puppet, that make ops live much easier.
