3 years ago - Number of pods will need to reduce to 12 from 15 due to persistent volume, node count/VM size restraints
- When deleting a Statefulset, the persistent volume claims do not auto delete themselves and thus the persistent volumes also do not auto delete. This is also the case when number of replicas are decreased eg: 12 agents down to 10. Two persistent volumes will not be deleted. https://github.com/kubernetes/kubernetes/issues/55045
- disks are using default StorageClassName using Standard SSD's
- disks are sized 4Gi the lowest tier available. Anything set under 4Gi will not have any cost saving effect - https://azure.microsoft.com/en-gb/pricing/details/managed-disks/
