Working with plug-in based disk snapshots

As a cloud administrator, you can create and manage plug-in based snapshots of Google Cloud Platform (GCP) disks in Automation Assembler.

If you need to create a backup of a disk, you can use the Snapshot resource in your cloud templates. You can attach the Snapshot resource to any type of disk. You can also create a new instance or disk using a snapshot. After the snapshot is created, you can log in to your Google Cloud Console to see the snapshot.

The following section contains some example cloud templates for using snapshots.

Creating a snapshot of a boot disk

The following cloud template shows how you might take a snapshot of a boot disk that is attached to an Instance. In this example, you use a compute helper, a network helper, an image helper, and a flavor helper.

  Allocations_Flavor_1:
    type: Allocations.Flavor
    properties:
      flavor: small
  mysql:
    type: Idem.GCP.COMPUTE.INSTANCE
    properties:
      name: mysql
      zone: ${resource.Allocations_Compute_1.selectedPlacementCompute.id}
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      project: ${resource.Allocations_Compute_1.selectedCloudAccount.additionalProperties.gcp.project}

      disks:
        - device_name: ${resource.mysql-boot-disk.name}
          source: ${resource.mysql-boot-disk.resource_id}
          boot: true
        - boot: false
          device_name: ${resource.mssql-attached-disk.name}
          source: ${resource.mssql-attached-disk.resource_id}
      machine_type: ${'/projects/' + resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project + '/zones/' + resource.Allocations_Compute_1.selectedPlacementCompute.id + '/machineTypes/' + resource.Allocations_Flavor_1.selectedInstanceTypeName}
  mssql-attached-disk:
    type: Idem.GCP.COMPUTE.DISK
    properties:
      name: attached-disk
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      size_gb: 1
      project: ${resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project}
      zone: ${resource.Allocations_Compute_1.selectedPlacementCompute.name}
      type: ${'/projects/' + resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project + '/zones/' + resource.Allocations_Compute_1.selectedPlacementCompute.id + '/diskTypes/pd-extreme'}
  mysql-boot-disk:
    type: Idem.GCP.COMPUTE.DISK
    properties:
      name: mysql-boot-disk
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      size_gb: 12
      project: ${resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project}
      zone: ${resource.Allocations_Compute_1.selectedPlacementCompute.name}
      type: ${'/projects/' + resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project + '/zones/' + resource.Allocations_Compute_1.selectedPlacementCompute.id + '/diskTypes/pd-balanced'}
  mysql-disk-snapshot:

    properties:
      name: mysql-boot-disk-snapshot
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      source_disk: ${resource.mysql-boot-disk.resource_id}

You use bindings to pass in the resource_id of mysql-boot-disk to the Snapshot resource.

Creating a new nstance from a snapshot

The following cloud template shows how to create a new instance from a snapshot. In this example, you also use a compute helper, image helper, network helper, and flavor helper.

    type: string
    title: Disk Snapshot Link id
resources:
  Allocations_Image_1:

  Allocations_Network_1:
    type: Allocations.Network
    properties:
      networkType: existing
  Allocations_Compute_1:

    properties:

    properties:
      name: mysql-from-snapshot
      zone: ${resource.Allocations_Compute_1.selectedPlacementCompute.id}
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      project: ${resource.Allocations_Compute_1.selectedCloudAccount.additionalProperties.gcp.project}
      network_interfaces:
        - name: nic0
          stack_type: IPV4_ONLY
          subnetwork: ${'/projects/' + resource.Allocations_Compute_1.selectedCloudAccount.additionalProperties.gcp.project + '/regions/' + resource.Allocations_Compute_1.selectedRegion.id + '/subnetworks/' + resource.Allocations_Network_1.selectedSubnet.name}
      disks:
        - device_name: ${resource.restored-disk.name}
          source: ${resource.restored-disk.resource_id}
          boot: true
      machine_type: ${'/projects/' + resource.Allocations_Flavor_1.selectedCloudAccount.additionalProperties.gcp.project + '/zones/' + resource.Allocations_Compute_1.selectedPlacementCompute.id + '/machineTypes/' + resource.Allocations_Flavor_1.selectedInstanceTypeName}
  restored-disk:
    type: Idem.GCP.COMPUTE.DISK
    properties:
      name: restored
      account: ${resource.Allocations_Compute_1.selectedCloudAccount.name}
      disk_name: restored-boot
      zone: ${resource.Allocations_Compute_1.selectedPlacementCompute.id}
      source_snapshot: ${input.disk-snapshot-Id}
      boot: true

You use input parameters to allow users to input the snapshot-Id of the snapshot they want to use for the boot disk.
