Welcome to the PowerShell Reference Guide. This guide will provide you with a reference to key PowerShell commands necessary for Azure administrators as well as required to pass the Azure Administrator certification exams from Microsoft AZ-104

🔧 Technologies & Tools

Cheatsheet with the most common Microsoft Azure PowerShell commands with examples.

Each section covers one specific set of resources you can manage with your Azure PowerShell Module Per each section you will find the following information:

• Title: The resources set name that you can manage with the Azure PowerShell Module
• Command: Remember this one. It's the basic thing to start. For instance, Get-AzResourceGroup is all about manage resource groups.
• Basic actions: Basic actions you can do in the command. Tip: mentally join command and basic action and you will be at half way to use the AZ Module to manage the resource.
• Examples: Set of examples using that command and the basic actions. First, it is described in human expression what you want to perform and the line after, the command that perform the action. Try to link the way of thinking and the sequence of the command and you will never forget a command again.

Note: In the examples is assumed that all the actions are based on your subscription account.

Azure PowerShell Cheatsheet

Check out the Microsoft Azure PowerShell Overview which has a number of tutorials and guides for learning the basics. This guide is made up of several PowerShell commands which have been reference from the Microsoft documentation and other sources. Before running any of these commands in production, please be sure to test them out in an Azure test account. Some commands are destructive in nature (e.g. removing resource groups, tags etc.) and you need to make sure you fully understand the commands that you execute.

The guide is divided up into the following sections:

1. Downloading PowerShell and Installing Azure AZ Modules for PowerShell
2. Accounts and Subscriptions
3. Resource Groups
4. Governance
5. Storage
6. Virtual Machines
7. Networking
8. Azure Active Directory

**Accounts and Subscriptions **

Azure Accounts

Login to Azure Account

Login-AzAccount 

Logout of the Azure account you are connected with in yoursession

Logout-AzAccount 

Subscription Selection

List all subscriptions in all tenants the account can access

Get-AzSubscription

Get subscriptions in a specific tenant

Get-AzSubscription -TenantId "xxxx-xxxx-xxxxxxxx"

Choose subscription

Select-AzSubscription –SubscriptionID “SubscriptonID” 

Resource Groups

Retrieving Resource Groups

Get all resource groups (Gets the resource group and additional details which can also be stored for use by additional commands).

Get-AzResourceGroup 

Get a specific resource group by name

Get-AzResourceGroup -Name "myResourceGroup”

Get resource groups where the name begins with "Production"

Get-AzResourceGroup | Where ResourceGroupName -like Production*

Show resource groups by location

Get-AzResourceGroup | Sort Location,ResourceGroupName | Format-Table -GroupBy Location ResourceGroupName,ProvisioningState,Tags

Resources within RGs

Find resources of a type in resource groups with a specific name

Get-AzResource -ResourceGroupName "myResourceGroup"

Find resources of a type matching against the resource name string

Note: The difference with this command vs the one above, is that this one does not look for a specific resource group, but rather just all resources with a name containing the text specified.

Get-AzResource -ResourceType
"microsoft.web/sites" -ResourceGroupName
"myResourceGroup"

Resource Group Provisioning & Management

###Create a new Resource Group

New-AzResourceGroup -Name 'myResourceGroup' -Location 'westeurope' #Creates a new resource group in West Europe called "myResourceGroup"

Delete a Resource Group

Remove-AzResourceGroup -Name "ResourceGroupToDelete"

Moving Resources from One Resource Group to Another

Step 1: Retrieve existing Resource

$Resource = Get-AzResource -ResourceType
"Microsoft.ClassicCompute/storageAccounts" - #Retrieves a storage account called  "myStorageAccount"
ResourceName "myStorageAccount" 

Step 2: Move the Resource to the New Group

Move-AzResource -ResourceId
$Resource.ResourceId -DestinationResourceGroupName - #Moves the resource from Step 1 into the destination resource group "NewResourceGroup"
"NewResourceGroup" 

Resource Group Tags

Display Tags associated with a specific resource group name

(Get-AzResourceGroup -Name "myResourceGroup").Tags

To get all Azure resource groups with a specific tag:

(Get-AzResourceGroup -Tag @{Owner="DesiredOwner"}).Name

To get specific resources with a specific tag:

(Get-AzResource -TagName Dept -TagValue Finance).Name

Adding Tags

###Add Tags to an existing resource group that has no tags

Set-AzResourceGroup -Name examplegroup -Tag @{Dept="IT"; Environment="Production" }

Adding tags to an existing

resource group that has tags

1. Get Tags
2. Append
3. Update/Apply Tags

$tags = (Get-AzResourceGroup -Name
examplegroup).Tags
$tags += @{Status="Approved"}
Set-AzResourceGroup -Tag $tags -Name examplegroup 

Add tags to a specific resource without tags

$r = Get-AzResource -ResourceName examplevnet -ResourceGroupName examplegroup Set-AzResource -Tag @{ Dept="IT";Environment="Production" } -ResourceId $r.ResourceId -Force

Apply all tags from an existing resource group to the resources beneath. (Note: this overrides all existing tags on the resources inside the RG)

$groups = Get-AzResourceGroup foreach
($group in $groups)
{
 Find-AzResource -
ResourceGroupNameEquals $g.ResourceGroupName |
ForEach-Object {Set-AzResource -ResourceId
$_.ResourceId -Tag $g.Tags -Force } } 

Apply all tags from a resource group to its resources, but retain tags on resources that are not duplicates

$groups = Get-AzResourceGroup foreach ($g
in $groups)
{
 if ($g.Tags -ne $null) {
 $resources = Find-AzResource
ResourceGroupNameEquals $g.ResourceGroupName
foreach ($r in $resources)
 {
 $resourcetags = (Get-AzResource
-ResourceId $r.ResourceId).Tags
 foreach ($key in $g.Tags.Keys)
 { 
 if
($resourcetags.ContainsKey($key)) {
$resourcetags.Remove($key) }
 }
 $resourcetags += $g.Tags
Set-AzResource -Tag
$resourcetags -ResourceId $r.ResourceId -Force
 }
 }
} 
 

Remove all tags

Removes all tags by passing an empty hash

Set-AzResourceGroup -Tag @{} -Name exampleresourcegroup

Governance

Test for a unique domain name

Test-AzDnsAvailability -DomainNameLabel "myDNS" -Location $location

You can specify a DNS domain name for a public IP resource, which creates a mapping for domainname.location.cloudapp.azure.com to the public IP address in the Azuremanaged DNS servers. The name can contain only letters, numbers, and hyphens. The first and last character must be a letter or number and the domain name must be unique within its Azure location. If True is returned, your proposed name is globally unique.

Create a public IP address

$pip = New-AzPublicIpAddress -Name "myPublicIp" -ResourceGroupName “resourcegroup” -DomainNameLabel "myDNS" -Location $location AllocationMethod
Dynamic #The public IP address uses the domain name that you previously tested and is used by
the frontend configuration of the load balancer. 

Create a frontend IP configuration

$frontendIP = New-AzLoadBalancerFrontendIpConfig -Name "myFrontendIP" PublicIpAddress $pip #The frontend configuration includes the public IP address that you previously created for incoming network traffic.

Reset an ExpressRoute circuit

When an operation on an ExpressRoute circuit doesn't complete successfully, the circuit might go into a "failed" state. You can reset a failed ExpressRoute circuit using Azure PowerShell. You will need the latest version of the Azure Resource Manager PowerShell cmdlets.

$ckt = Get-AzExpressRouteCircuit -Name "ExpressRouteARMCircuit" -ResourceGroupName "ExpressRouteResourceGroup"

Set-AzExpressRouteCircuit -ExpressRouteCircuit $ckt

Identify the root cause for ExpressRoute latency issues

To troubleshoot latency issues with ExpressRoute, the Azure Connectivity Toolkit includes a tool called iPerf.

You use iPerf for basic performance tests, by copying the files to a directory on the host. To test performance, follow these steps:

1. Install the PowerShell Module.

(new-object Net.WebClient).DownloadString("https://aka.ms/AzureCT") | Invoke-Expression

This command downloads the PowerShell module and installs it locally.

2. Install the supporting applications.

Install-LinkPerformance

This AzureCT command installs iPerf and PSPing in a new directory, "C:\ACTTools". It also opens the Windows Firewall ports to allow ICMP and port 5201 (iPerf) traffic.

3. Run the performance test. First, on the remote host, you must install and run iPerf in server mode. Ensure the remote host is listening on either 3389 (RDP for Windows) or 22 (SSH for Linux) and allowing traffic on port 5201 for iPerf. If the remote host is Windows, install the AzureCT and run the Install-LinkPerformance command. The command will set up iPerf and the necessary firewall rules.

When the remote machine is ready, open PowerShell on the local machine and start the test:

Get-LinkPerformance -RemoteHost IP -TestSeconds 10

This command runs a series of concurrent load and latency tests to help estimate the bandwidth capacity and latency of your network link.

4.Review the output of the tests.

The detailed results of iPerf tests are in individual text files in the AzureCT tools directory at "C:\ACTTools."

Azure Active Directory Commands Install Azure AD Module In order to use the Azure AD commands, you first need to install the Azure AD module. Use the following procedure to get it installed:

1. Open PowerShell
2. Type “Install-Module AzureAD”
3. Press Y to accept the untrusted repository (PSGallery)

Connect to Azure AD

Connect to Azure Active Directory

Connect-AzureAD #Note: You will be prompted to enter your credentials and any additional authentication steps required.

Disconnect from Azure Active Directory

Disconnect-AzureAD

User and service principal management

Get all users

Get-AzureADUser

Get specific user

Get-AzureADUser -ObjectId "[email protected]"

Remove User

Remove-AzureADUser -ObjectId "[email protected]"

New User Creation

This is a 3 step process that requires first creating a password profile, setting the password, and then passing these into the NewAzureADUser command

1. Create Password Profile

$PasswordProfile = New-Object -TypeName Microsoft.Open.AzureAD.Model.PasswordProfile

2. Set Password

$PasswordProfile.Password = "Password"

3. Create User

New-AzureADUser -DisplayName "New User" -PasswordProfile $PasswordProfile -UserPrincipalName "[email protected]" -AccountEnabled $true -MailNickName "Newuser"

Service Principal Creation

First you need to create your application registration in AzureAD then you retrieve it with this command.

Get-AzADApplication -DisplayNameStartWith slappregistration

Once you have the application ID for the App registration, you can use it to create the SPN (Service Principal)

New-AzADServicePrincipal -ApplicationId 11111111-1111-1111-1111-11111111111 -Password $securePassword 

Assign Role

This will be scoped to the resource group name you type in with the role definition assigned to the SPN i.e. The SPN is allowed to do X at the RG named Y

New-AzRoleAssignment -ResourceGroupName “resourcegroup” -ObjectId 11111111-1111-1111-1111-11111111111 -RoleDefinitionName Reader

View Current Role Assignment

 Get-AzRoleAssignment -ResourceGroupName “resourcegroup” -ObjectId 11111111-1111-1111-1111-11111111111
