Dynamic Disks in Cloud Template no longer work with the count parameter

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

 

• After upgrading to Aria 8.18 and above Cloud Template YAML now flags a warning label for the attachedDisks property of Cloud Machine resources which include a count property.
•  
• The error message reads:
  "The entries under the attachedDisks array must reference either clustered or non-clustered resources only. You can either use the map_to_object expression or add count:1 to convert a non-clustered to a clustered resource, or you can remove the count to convert a clustered resource to non-clustered."

Environment

Aria Automation 8.18 (vRA)

Cause

The Cloud Template YAML editor is stricter in the later releases when it comes to referencing the count property.

Resolution

Ensure that all volumes under resources that are referenced in the attachedDisk property have a count assigned, either statically, or as a variable.

In this YAML example, there are 4 dynamically assigned Cloud Volumes where the user can choose to add 0-4 disks:

resources:
  Cloud_Volume_1:
    type: Cloud.Volume
    properties:
      capacityGb: ${input.disksize_1}
            count: '${input.num_xdisks >= 2 ? 1 : 0}'
      volumeType: gp3
  Cloud_Volume_2:
    type: Cloud.Volume
    properties:
      capacityGb: ${input.disksize_2}
      count: '${input.num_xdisks >= 2 ? 1 : 0}'
      volumeType: gp3
  Cloud_Volume_3:
    type: Cloud.Volume
    properties:
      capacityGb: ${input.disksize_3}
      count: '${input.num_xdisks >= 3 ? 1 : 0}'
      volumeType: gp3
  Cloud_Volume_4:
    type: Cloud.Volume
    properties:
      capacityGb: ${input.disksize_4}
      count: '${input.num_xdisks >= 4 ? 1 : 0}'
      volumeType: gp3

 

 

 

  Cloud_Instance_1:
    type: Cloud.Machine
    properties:
      attachedDisks: ${map_to_object(resource.Cloud_Volume_4[*].id + resource.Cloud_Volume_3[*].id + resource.Cloud_Volume_2[*].id + resource.Cloud_Volume_1[*].id,"source")}
