Default values prevent AKS from upgrading Kubernetes version and node image

PodDisruptionBudget prevents cluster from upgrading when controller.replicaCount = 1. I would like to suggest you to change controller.replicaCount default value to 2.

Makes sense, thanks for sharing. I'd however add a PodDisruptionBudget only if minAvailable is between 1 and replicas-1, what do you think? #73 implements that approach.

Should be solved in the next controller releases. Closing.

Thank you. I think adding a PodDisruptionBudget only if minAvailable is between 1 and replicas-1 is a good idea.
