aks_create_scale.yml

# Description
# ===========
# This playbook first creates an Azure Kubernetes Service cluster of 2 nodes with provided username and ssh key and scales it to 3 nodes.
# Change variables below to customize your AKS deployment.
# It also requires a valid service principal to create AKS cluster, so fill:
# - client_id
# - client_secret
# This sample requires Ansible 2.6
