Find cheapest spot supported size / sku via az CLI or terraform provider-CodePudding

Trying to automate spot instance creation using Azure CLI. Neither az vm list-sizes nor az vm list-skus --resource-type virtualMachines seems to show any "spot supported" filter(s).

I looked at terraform azurerm provider, but did not find any data source related to this under compute.

How does one figure out cheapest spot instance from a given region that meets some criteria (core count, memory, etc) ?

C:\Users\foo> az --version

Looking at the documentation:

The following VM sizes are not supported for Azure Spot Virtual Machines:

B-series

Promo versions of any size (like Dv2, NV, NC, H promo sizes)

So you could write an az cli query to exclude them:

az vm list-sizes --location "<location>" `
  --query "[?!contains(name, 'Promo') || !contains(name, 'Standard_B')]"

The Azure Pricing API could then help to find out pricing:

az rest --method get `
  --uri "https://prices.azure.com/api/retail/prices?`$filter=serviceName eq 'Virtual Machines' and armRegionName eq '<location>' and (contains(armSkuName, 'Promo') eq false and contains(armSkuName, 'Standard_B') eq false)"
