@anaik91 Given the following requiremnts:

• Ability for users to define the storage class name, provisioner and parameters in the vars file, the storage class should be crated by the playbook
• Provide validation to make sure users cannot change the storage class if a cassandra statefulset already exists in the environment.
• Validate the storage class provided by the user against the actual underlying k8s platform.

With regard to the 3rd requirement, can we converge on a set of platforms we want to support? There does not seem to be a standard way to identify the underlying provider of the k8s platform. For example with node-labels we can potentially identify the platform as GKE or AWS, however there does not seem to be a standard around this. Let me know your thoughts on this
