Microsoft.Compute.SizeSelector UI element

  • Article

A control for selecting a size for one or more virtual machine instances.

UI sample

The user sees a selector with default values from the element definition.

Microsoft.Compute.SizeSelector

After selecting the control, the user sees an expanded view of the available sizes.

Schema

{
  "name": "element1",
  "type": "Microsoft.Compute.SizeSelector",
  "label": "Size",
  "toolTip": "",
  "recommendedSizes": [
    "Standard_D1",
    "Standard_D2",
    "Standard_D3"
  ],
  "constraints": {
    "allowedSizes": [],
    "excludedSizes": [],
    "numAvailabilityZonesRequired": 3,
    "zone": "3"
  },

    "hideDiskTypeFilter": false
  },

  },
  "count": 2,
  "visible": true
}

Sample output

"Standard_D1"

Remarks

  • recommendedSizes should have at least one size. The first recommended size is used as the default. The list of available sizes isn't sorted by the recommended state. The user can select that column to sort by recommended state.
  • If a recommended size isn't available in the selected location, the size is automatically skipped. Instead, the next recommended size is used.
  • constraints.allowedSizes and constraints.excludedSizes are both optional, but can't be used simultaneously. The list of available sizes can be determined by calling List available virtual machine sizes for a subscription. Any size not specified in the constraints.allowedSizes is hidden, and any size not specified in constraints.excludedSizes is shown.
  • osPlatform must be specified, and can be either Windows or Linux. It's used to determine the hardware costs of the virtual machines.
  • imageReference is omitted for first-party images, but provided for third-party images. It's used to determine the software costs of the virtual machines.
  • count is used to set the appropriate multiplier for the element. It supports a static value, like 2, or a dynamic value from another element, like [steps('step1').vmCount]. The default value is 1.
  • The numAvailabilityZonesRequired can be 1, 2, or 3.
  • By default, hideDiskTypeFilter is false. The disk type filter enables the user to see all disk types or only SSD.
