Customize Machine Properties or Deployments with Extensibility Topics

You can update machine properties or deployments by using the available extensibility topics during the deployment life cycle.
Verify that you have access to the extensibility code samples package.
To update the deployment payload, you can create new subscriptions using available extensibility topics such as
Provisioning Request
and
Disk Allocation
that call
Automation Orchestrator
workflows or extensibility actions.
  1. To customize machine CPU or memory properties, create a new extensibility subscription.
    1. Enter a subscription name. For example,
      Customize CPU/Memory
      .
    2. In
      Event Topic
      , select
      Provisioning request
      .
    3. Next to
      Action/workflow
      , set an output of type String called
      flavor
      .
      You cannot change the machine CPU and memory properties directly if you do not set a new flavor mapping. The output property must be called
      flavor
      , and the value must be an existing flavor mapping profile.
      The following code snippet is taken from a sample extensibility action.
      def handler(context, inputs): outputs = { "flavor": "large" } return outputs
  2. To customize disk allocation, create another extensibility subscription.
    1. Enter a subscription name. For example, you can name it
      Disk size
      .
    2. In
      Event Topic
      , select
      Disk allocation
      .
    3. Next to
      Action/workflow
      , set an output of type Array called
      diskSizesInGb
      .
      The following code snippet is taken from a sample
      Automation Orchestrator
      workflow.
      // Customize the size of the first VM disk var vm_disks = inputProperties.get("diskSizesInGb"); if (isParameterReadOnly("diskSizesInGb") == false) { vm_disks[0]=30; } diskSizesInGb = vm_disks;
  3. Request a new virtual machine from the VMware Aria Automation Catalog Item.
Once the deployment is ready, navigate to the virtual machine settings. Verify that the CPU, memory, or disk size are set to the values configured in the extensibility action or
Automation Orchestrator
workflow that are used in the subscriptions you created.
