Azure - Grafana+Prometheus deployments fail with "Addition of a managed disk to a VM with blob based disks is not supported."

[shaharyakir]

I'm running on Azure with acs-engine.

The deployment script ends successfully, but the pods are not able to start:

Warning FailedMount 15s (x2 over 1m) attachdetach AttachVolume.Attach failed for volume "pvc-f1da4bbd-f6dc-11e7-a367-000d3a1b19fd" : Attach volume "XXX-dynamic-pvc-f1da4bbd-f6dc-11e7-a367-000d3a1b19fd" to instance "k8s-nodepool1-18946821-0" failed with compute.VirtualMachinesClient#CreateOrUpdate: Failure responding to request: StatusCode=409 -- Original Error: autorest/azure: Service returned an error.

@shaharyakir I'm not very familiar with Azure, but willing to fix this. acs-engine and Azure Container Service (AKS) are the same now? I remember Azure supporting Kubernetes for quite long time, but only tested AKS recently and it was on preview.

[shaharyakir]

no, AKS is the very-limited, Microsoft official implementation.

acs-engine is open source and configurable.

Hi, you should be deploying your cluster with managed disks. You would need to create your cluster with this see here.

If you were insistent on using blob-based storage you would need to customise manifests/prometheus/prometheus-k8s.yaml and change the storage class to azure blob.

Ok, will check. Thank you.

@sjdweb Works. Thanks!
