Attaching an existing disk in Automation Assembler

Your Automation Assembler template code can attach an existing, deployed disk to a newly created machine.

Use the following cloud template code example as a guideline.

formatVersion: 1
inputs:
  disk:
    type: string
    $data: /data/availableDisks?resourceType=Cloud.Volume
resources:
  Cloud_Machine_1:
    type: Cloud.Machine
    properties:
      image: ubuntu
      flavor: small
      attachedDisks: 
        - source: ${input.disk}

The highlighted line is an API call that lists the disks that are available for attachment, disks unattached to any machine.

The resourceType parameter lets Automation Assembler list available disks by cloud account type.

Cloud.Volume	Disks on any cloud that you have added
Cloud.vSphere.Disk	Only vSphere disks
Cloud.AWS.Volume	Only Amazon Web Services (AWS) disks
Cloud.Azure.Disk	Only Microsoft Azure disks
Cloud.GCP.Disk	Only Google Cloud Platform (GCP) disks

When using this feature, there's no design canvas component for the existing disk that you attach. Even though there's no component on the design canvas, the attached disk appears under the storage section of the deployed machine, and under the Resources tab.
