Get OS Type of an VM Image in azure RM

According to this we can get the offer , publisher and Sku in AzureRM Cloud .

Now How to get the Image's OS type(Windows or Linux) using any of the API in azure ? Because using this I can be only able to get the Publisher , offer and sku details , Can't get the OS type .

My Question is how to get the OS type for any images programmatically?

You could use Azure CLi 2.0 to get OS type.

Using az vm image show, for example:

latest=$(az vm image list -p OpenLogic -s 7.3 --all --query     "[?offer=='CentOS'].version" -o tsv | sort -u | tail -n 1)
az vm image show -l westus -f CentOS -p OpenLogic --s 7.3 --version ${latest}

It will return following result

{
  "additionalProperties": {},
  "dataDiskImages": [],
  "id": "/Subscriptions/*************/Providers/Microsoft.Compute/Locations/westus/Publishers/OpenLogic/ArtifactTypes/VMImage/Offers/CentOS/Skus/7.3/Versions/7.3.20170925",
  "location": "westus",
  "name": "7.3.20170925",
  "osDiskImage": {
    "additionalProperties": {},
    "operatingSystem": "Linux"
  },
  "plan": null,
  "tags": null
}

Note:operatingSystem is the OS type you want. The example works on bash shell.

If you use az vm image show -l westus -f CentOS -p OpenLogic --s 7.3 --version ${latest} --debug, you will find the API that could get the OS type.
