Attempting to tag an existing azure public ip of an instance within a vm scaleset gives a resource not found

Bug Report

• import path of package in question, e.g. .../services/compute/mgmt/2018-06-01/compute
"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v5"

• SDK version e.g. master, latest, 18.1.0

  • Specify the exact commit if possible; one way to get this is the REVISION
    column output by go list -m <module>, for example go list -m github.com/Azure/azure-sdk-for-go/sdk/azcore.

• output of go version
github.com/Azure/azure-sdk-for-go/sdk/azcore v1.14.0
github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/network/armnetwork/v5 v5.2.0

• What happened?
  I deployed a VM scaleset with 1 instance that has both the public and private IPs created.
  On calling go sdk function - func (client *PublicIPAddressesClient) UpdateTags(ctx context.Context, resourceGroupName string, publicIPAddressName string, parameters TagsObject, options *PublicIPAddressesClientUpdateTagsOptions) (PublicIPAddressesClientUpdateTagsResponse, error) ,it gives the following error

RESPONSE 404: 404 Not Found\nERROR CODE: ResourceNotFound 
{
 "error": {
  "code": "ResourceNotFound", 
  "message": "The Resource 'Microsoft.Network/publicIPAddresses/<identifier>' under resource group '<identifier>' was not found. For more details please go to https://aka.ms/ARMResourceNotFoundFix"
 }
}

On checking the fully qualified namespace of the public IP created for the instance within the namespace, it looks like the SDK call is looking for the public IP address in a different namespace and the public IP for the instance in the VM scaleset is created in a different namespace.

/subscriptions/<identifier>/resourceGroups/<identifier>/providers/Microsoft.Compute/virtualMachineScaleSets/<identifier>/virtualMachines/0/networkInterfaces/<identifier>/ipConfigurations/<identifier>/publicIPAddresses/<identifier>

Not sure if a wrong SDK method is called here or is this a bug?

• What did you expect or want to happen?
  I expected the public IP belonging to the instance in the VM scaleset to be updated with all the tags i provided.

• How can we reproduce it?
  Using the azure golang sdk.
  Please deploy a VM scaleset with 1 instance and check the public IP is assigned.
  Call the method above to update the tags of the public IP address.
  The tag updation fails with the error mentioned above.

• Anything we should know about your environment.

Hi @neville-cb thanks for this issue
I think the public ip address resource you created with your vmss is not the same resource in the network RP therefore it cannot be managed by the PublicIPAddressClient in armnetwork package.
And also that public ip resource created by vmss does not have a tag to assign.

Thanks for getting back @ArcturusZhang

And also that public ip resource created by vmss does not have a tag to assign.

Do you mean tagging a public IP belonging to an instance within a VMSS is not yet supported? Because i attempted to tag it via the Azure UI portal by clicking on Add Tags and it threw some error message. Refer screenshot below

And if it's not yet supported then are there any plans to allow doing that in the future?

[ArcturusZhang]

Hi @neville-cb I believe the service API does not support it yet, I do not know if there is any plan for this on VMSS service teams.
If they added the API in the future, we could support it instantly in our SDK - but we are not able to do that if the API does not support it.
As for the plans on service teams, maybe you could try to create support tickets on azure portal directly to VMSS team to ask
