Azure Powershell command cannot find my VM under my resource group? - azure

Question

I'm trying to change the TCP Port timeout on my Ubuntu VM in Azure, and am following this guide to do so, however I seem to get stuck at Step 8 where I have to type the following command:
Get-AzureRmVM -Name "digitron" -ResourceGroup "DIGITRON-RG" |
Get-AzureRmPublicIpAddress
Where it spits back the following error:
Get-AzureRmPublicIpAddress : The Resource 'Microsoft.Network/publicIPAddresses/digitron' under resource group
'DIGITRON-RG' was not found.
StatusCode: 404
ReasonPhrase: Not Found
OperationID : '5031da35-262c-4e1a-a85b-885a6a0fd36c'
At line:1 char:63
+ ... "digitron" -ResourceGroup "DIGITRON-RG" | Get-AzureRmPublicIpAddress
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : CloseError: (:) [Get-AzureRmPublicIpAddress], NetworkCloudException
+ FullyQualifiedErrorId : Microsoft.Azure.Commands.Network.GetAzurePublicIpAddressCommand
What's strange here is if I run the command Get-AzureRmVm, the powershell will spit back:
ResourceGroupName Name Location VmSize OsType NIC ProvisioningState
DIGITRON-RG digitron eastus Standard_DS2_v2 Linux digitron727 Succeeded
Now reading the error makes me think that the VM itself has no public IP address, but I've set it in the Azure Portal as seen in this image (where it says 40.71.98.172 etc):
Why is the Powershell giving me this error?

Answer 1

The Resource 'Microsoft.Network/publicIPAddresses/digitron' under
resource group 'DIGITRON-RG' was not found.
Because Get-AzureRmPublicIpAddress can't get the right parameter, this error means the resource can't find in DIGITRON-RG. For test, we can use Get-AzureRmResource to test the resource exist or not:
PS > Get-AzureRmResource | ?{$_.name = "digitron"}
By the way, the command Get-AzureRmPublicIpAddress need parameters: -Name (the name of the public IP address), -ResourceGroupName (the name of the resource group)
PS > Get-AzureRmPublicIpAddress -Name "jason-ip" -ResourceGroupName "jason"
Name : jason-ip
ResourceGroupName : jason
Location : eastus
Id : /subscriptions/5xxxxabb-222b-49c3-9488-0361e29a7b15/resourceGroups/jason/providers/Microsoft.Network/publicIPAddresses/jason-ip
Etag : W/"5a7200b2-7c2b-4c7a-be27-0bbb7c8f4665"
ResourceGuid : 32xxxf-750a-46a4-abda-c25xxx2b64
ProvisioningState : Succeeded

PublicIpAllocationMethod : Dynamic
IpAddress : 13.92.255.103
PublicIpAddressVersion : IPv4
IdleTimeoutInMinutes : 30
IpConfiguration : {
"Id": "/subscriptions/5xxxxb-222b-49c3-9xx8-0361e29a7b15/resourceGroups/jason/providers/Microsoft.Network/networkInterfaces/jason647/ipConfigurations/ipconfig1"
}
DnsSettings : null
We can use this command to get the public IP direct, and increase the timrout to 30 minutes.

Below is the script I used to get the Private and Public IP for an Azure ARM VM:
$rg = Get-AzureRmResourceGroup -Name "MyResourceGroup01"
$vm = Get-AzureRmVM -ResourceGroupName $rg.ResourceGroupName -Name "MyVM01"
$nic = Get-AzureRmNetworkInterface -ResourceGroupName $rg.ResourceGroupName -Name $(Split-Path -Leaf $VM.NetworkProfile.NetworkInterfaces[0].Id)
$nic | Get-AzureRmNetworkInterfaceIpConfig | Select-Object Name,PrivateIpAddress,#{'label'='PublicIpAddress';Expression={Set-Variable -name pip -scope Global -value $(Split-Path -leaf $_.PublicIpAddress.Id);$pip}}
(Get-AzureRmPublicIpAddress -ResourceGroupName $rg.ResourceGroupName -Name $pip).IpAddress
#Output:
Name PrivateIpAddress PublicIpAddress
