I have a worker role that performs web scraping. I need to determine the IP from which it works when deployed on Azure. How do I do that?
If you need the public VIP address, that can be obtained from the Windows Azure management portal. It's on the dashboard for the selected Cloud Service (about half way down on the right).
You can use InstanceEndpoints property of the RoleInstance... you can get all role instances executing by using the RoleEnvironment class, and then find the role you are interested in.
RoleInstance.InstanceEndpoints Property - there is a sample showing all of this.
Using Azure PowerShell You can use like this -
Get-AzureRole -ServiceName "abc" -Slot "production" -InstanceDetails | select {$_.InstanceEndpoints[0].VIP }

I am creating an ARM template for the Azure Log Analytics workspace.it has some queries which use azure VM's VMUUID. Is there is any way to fetch the azure VM's VMUUID inside the ARM template or any other way to fetch azure VMUUID?
ARM Template I just need to get the values of VMUUID of all VM's in that subscription.
You can also get this information programmatically from the Azure Instance Metadata Service (IMDS). It provides information about currently running virtual machine instances. You can use IMDS to manage and configure your virtual machines. This information includes the SKU, storage, network configurations, and upcoming maintenance events. For a complete list of the data available, see the Endpoint Categories Summary.
IMDS is a REST API that's available at a well-known, non-routable IP address 169.254.169.254. You can only access it from within the VM. Communication between the VM and IMDS never leaves the host.

Try Azure Resource Explorer
You could easily find it in the Azure Resource Explorer.
//One more extra reference: What is Azure Resource Explorer?
Just navigate to the Microsoft.Compute => virtualMachines view:
There is one more way to find it, but for me seems more complicated as you need to connect to the VM:
https://azure.microsoft.com/en-us/blog/accessing-and-using-azure-vm-unique-id/
Update: Try PowerShell
The simple PowerShell script below returns a list of all VMUUIDs in the specified subscription:
Get-AzSubscription
Select-AzSubscription -SubscriptionId "Olga's Subscription"
$GetVM = Get-AzVM
Foreach ($vm in $GetVM)
{
$vmId =""
$vmId = $vm.vmid
$vmIdList +=$vmId + "`r`n"
}
Write-Output $vmIdList
Please let me know if above answers your question.
I want to configure the authentication for my Azure function via code, be it powershell, ARM template or an API? is this possible?
i'm under the impression that an Azure Function is nothing more then an App Service so i would assume it resolve around there.
https://learn.microsoft.com/en-us/powershell/module/az.websites/?view=azps-2.0.0#app_service - there doesn't seem to be anything in the powershell.
https://resources.azure.com/ doesn't seem to give much information.
Here is some documentation on how to use managed identities for App Service and Azure Functions: https://learn.microsoft.com/en-us/azure/app-service/overview-managed-identity
You could create an PowerShell function app with MSI (Managed Service Identity) enable in a consumption plan. Here is some documentation (https://azure.microsoft.com/en-us/resources/templates/101-functions-managed-identity/) on how to do that.
Once the function app is created, you can grant it access to a given resource https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azroleassignment?view=azps-2.0.0#examples
Lastly, the PowerShell function app comes with a profile.ps1 which contains code to authenticate against Azure via MSI out the box.
# Authenticate with Azure PowerShell using MSI.
# Remove this if you are not planning on using MSI or Azure PowerShell.
if ($env:MSI_SECRET -and (Get-Module -ListAvailable Az.Accounts)) {
Connect-AzAccount -Identity
}
Please give it a try and let us know if you run into any issues.
Azure Functions Authentication are still pending. Currently AFAIK there is not a way to add authentication via code except with the Function Host Keys
You can track the issue here in Github
Using terraform is a really good way of configuring these, a good example is below. Also az CLI 'az webapp auth' seems to have really good support now. PowerShell still seems to be lagging behind.

I am trying to find the availability sets in a Azure Cloud Service using powershell. The Cloud Service was created using classic model.
I am not sure if this is the right answer:
get-AzureService -ServiceName "myService"
That is correct. Get-AzureService returns with the information about the cloud services for the current subscription.
The Syntax is:
Get-AzureService -ServiceName "nameOfService"
I can use Azure Powershell to get a list of services from my subscription e.g. using Get-AzureService.
What I can't currently easily work out is how to tell if the service is a VM (new or classic) or a cloud service (web/worker role).
What I am currently doing to identify a cloud service is using Get-AzureDeployment on the service-name and looking for a non-empty SdkVersion property but I feel this is a bit cludgy. Is there a better way?
Afaik there's no way to do this through the Get-AzureService without using (as you said) the Get-AzureDeployment.
You should be able to fetch the information using the new AzureResourcemanager cmdlets (Switch-AzureMode -Name AzureResourceManager) and using Get-AzureResource.
The ResourceId (in ARM mode) will give you a clue of what kind of provider it is.
I have C# code running on an Azure Windows VM. Is there a way for me to find out what Resource Group this VM is in?
VM has been deployed with Azure Resource Management API (new, not classic)
The following will guarantee the ability to distinguish between vm's with the same name across different resource groups:
From your C# code, find the vmId (involves running one of the commands at the following link or possibly using an Azure SDK: https://azure.microsoft.com/en-us/blog/accessing-and-using-azure-vm-unique-id/). If using a Linux VM, be sure to take into account the different endian-ness, otherwise the vmId will not match.
Once you have the vmId, you can use either CLI or Powershell (or potentially an Azure SDK) to list all of the VM's in the subscription, then search through the list to find which VM has the vmId you got from the machine. Then you should be able to parse out the resource group name from the "id" field of the json for that VM (which, as Gaurav mentioned, is a string with the resource group in it). For an example, try the following:
azure vm list --json -vv
This command will show you the url's it is using to make the requests and the response body. In this body you will find the "vmId" and "id" field. For instance, one of the requests it sends is:
https://management.azure.com/subscriptions/{my-subscription-id}/providers/Microsoft.Compute/virtualMachines?api-version=2015-06-15
and the response body for this is the json with the relevant entries. Hope this helps! :)
One way to find out the resource group is to list all the virtual machines in your Azure Subscription. The URL you would use for that would be:
https://management.azure.com/subscriptions/[subscription-id]/providers/Microsoft.Compute/virtualMachines?api-version=2015-06-15
It will return you a list of all Virtual Machines in your Azure Subscription in JSON format where each item represents a Virtual Machine. You can first filter by the name property to find the matching Virtual Machine. Then the property which is important to you there is id which is always of the format:
/subscriptions/[subscription-id]/resourceGroups/[resource-group-name]/providers/Microsoft.Compute/virtualMachines/[virtual-machine-name]
You could simply parse this to get the resource group name.
How did you deploy the VM? Through portal.azure.com? Through CLI? Powershell? In any of these cases, usually you are required to specify a resource group name. In fact, in the portal, if you click on "Virtual Machines", it should say the resource group:
resource group of VM in portal
write-host(Get-AzVm -name "hostname").ResourceGroupName
