Azure Powershell programmatic login - powershell

I am working with Azure (HDInsight in particular) using a personal account (no work/school acocunt).
I would create a script that automatically login on azure and perform some actions.
I found a solutions saving an azure publishsetting json file after logging with our credentials but this settings file contains token that expires.
How can I deal with this issue? What is the best way to accomplish this automatico logon?
Thanks

You need to create a service principal. Once you've created the service principal you can assign it permissions on specific resources using Role-Based Access Control. From there your script can login as the service principal without requiring you to login interactively.
The main concern with this approach is securing access to your script since it contains credentials that allow access to your Azure resources.
This article has a good walkthrough:
#First, login as yourself so you can setup the service principal
Login-AzureRmAccount
#Password doesn't have to be *your* password, but the password the script will use
$app = New-AzureRmADApplication –DisplayName "<Your script name>" –HomePage "http://localhost" –IdentifierUris "http://localhost/YourAppName" –Password "<Password>"
#Create the service principal
New-AzureRmADServicePrincipal –ApplicationId $app.ApplicationId
#Assign the Reader role to your new service principal. Other roles listed at
#https://azure.microsoft.com/en-us/documentation/articles/role-based-access-built-in-roles/
New-AzureRmRoleAssignment –RoleDefinitionName Reader –ServicePrincipalName $app.ApplicationId
$pass = ConvertTo-SecureString "<Password>" -AsPlainText –Force
#Servce principal username looks like 92c22f1f-d1d4-46a1-b025-edb47fc03809#something.onmicrosoft.com
#the GUID part is $app.ApplicationId and the domain part is found in the Azure portal
$cred = New-Object -TypeName pscredential –ArgumentList "<Service Principal UserName>", $pass
Login-AzureRmAccount -Credential $cred -ServicePrincipal –TenantId <TenantId>

If it is not a production/shared setup and more a developer setup you can also do, careful, the password is plain text here:
$SubscriptionName = 'MySubscription'
$pswd = 'MyPassword' | ConvertTo-SecureString -AsPlainText -Force
$creds = New-Credential -UserName 'MyEmail#something.com' -Password $pswd
Add-AzureRmAccount -Credential $creds
Set-AzureRmContext -SubscriptionName $SubscriptionName
Login-AzureRmAccount -Credential $creds -SubscriptionName $SubscriptionName

Below information might help you
Create an Automation Account in Azure
Add your credentials in Automation Account as a variable ( e.g
variablename = loginazure) Below Script will automatically login into azure (use Powershell workflow runbook).
$AzureLogin = Get-AutomationPSCredential -Name 'loginazure'
$AzurePortalLogin = New-Object -TypeName System.Management.Automation.PSCredential$AzureLogin
Add-AzureRmAccount -Credential $AzurePortalLogin
Get-AzureRmSubscription -SubscriptionName "your subscription name" | Set-AzureRmContext
use the above script within Inline Script {}

Here are a couple of commands that you can fire up to get started.
$credentials = Get-Credential
Login-AzureRmAcoount -Credential $credentials
$SubscriptionName
Select-AzureRmSubscription -SubscriptionName "The name of your subscription"
Select-AzureRmSubscription -SubscriptionName $SubscriptionName

Azure Function calling a Powershell script and unattended login

I'm creating an Azure Function that will call a PowerShell script. In order to do this I need to have the PS script do an unattended login. So I created an application and Service Principal as follows:
# Create an Azure Active Directory Application that will be used for authentication in Powershell Automation scripts.
$Password = ConvertTo-SecureString '<MyPassword>' -AsPlainText -Force
$AzureAdApplication = New-AzureRmADApplication -DisplayName "PowerShellAdminApp" -Password $Password -HomePage "https://www.phoenix.com" -IdentifierUris "https://www.phoenix.com"
# Create the Service Principal
New-AzureRmADServicePrincipal -ApplicationId $AzureAdApplication.ApplicationId
# Add permissions to the Server Principal
New-AzureRmRoleAssignment -RoleDefinitionName Contributor -ServicePrincipalName $AzureAdApplication.ApplicationId.Guid
This all works correctly.
Then, in my PS script(s), I will log in, unattended, as follows:
$Username = "https://www.phoenix.com"
$Password = ConvertTo-SecureString "<MyPassword>" -AsPlainText -Force
$Credential = new-object -typename System.Management.Automation.PSCredential -argumentlist $Username, $Password
Login-AzureRmAccount -ServicePrincipal -Credential $Credential -TenantId '<MyTenantId'
This works as well. However, I feel like I'm not understanding something or I'm missing something. This is not at all secure. If I have to have this login code in all my PS scripts, I'm basically letting anyone who has access to these scripts see the tenant Id and the password to the app. They then could perform any activity the app can perform.
Am I doing this correctly or not understanding something?
You can use App Settings to define environment variables and store passwords there and in your code just read them:
$username = $env:username
$password = ConvertTo-SecureString $env:password -AsPlainText -Force
Here's how to configure that. https://learn.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings

Set-AzureRmContext error when executed within an Azure Automation Runbook

Update:
Seems like someone else had the same issue and reported it.
I am facing an issue with a simple PowerShell script when invoking it from an Azure Automation Runbook. The same piece of code works flawless when running it locally.
I have added a Service Principal in an Azure Active Directory (hosted in Azure German Cloud) with password credential and grant it contributor access to a subscription (also hosted in Azure German Cloud).
The Azure Automation service is hosted in North Europe since it's currently not available in the Azure German Cloud.
All I try to do is to login to my subscription with the above mentioned principal using the Add-AzureRmAccount cmdlet. After that I try to set the current context using the Set-AzureRmContext and getting the following error message:
Set-AzureRmContext : Please provide a valid tenant or a valid subscription.
At line:26 char:1
+ Set-AzureRmContext -TenantId $TenantId -Su ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : CloseError: (:) [Set-AzureRmContext], ArgumentException
+ FullyQualifiedErrorId : Microsoft.Azure.Commands.Profile.SetAzureRMContextCommand
Here is the script I try to run (left the configuration blank):
$TenantId = ""
$ApplicationId = ""
$ClientSecret = ""
$SubscriptionId = ""
$secpasswd = ConvertTo-SecureString $ClientSecret -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($ApplicationId , $secpasswd)
Add-AzureRmAccount -ServicePrincipal -Environment 'AzureGermanCloud' -Credential $mycreds -TenantId $TenantId
Set-AzureRmContext -TenantId $TenantId -SubscriptionId $SubscriptionId
I also tried to use Login-AzureRmAccount without success. Also I am able to use the Get-AzureRmResourceGroup cmdlet to retrieve the resource groups so the login seems to work.
All Azure modules are updated to the latest version.
TLTR:
My main goal is to start a SQL export job using the New-AzureRmSqlDatabaseExport from the runnbook but it seems like the above mentioned error causes the cmdlet to fail with the following message:
New-AzureRmSqlDatabaseExport : Your Azure credentials have not been set up or have expired, please run
Login-AzureRMAccount to set up your Azure credentials.
At line:77 char:18
+ ... rtRequest = New-AzureRmSqlDatabaseExport -ResourceGroupName $Resource
I had the same issue a few weeks ago and what worked was to first login to Azure account (which I think you already did) using:
Login-AzureRmAccount
Then get the subscription ID from Azure and use select the subscription using the ID instead of the name as follows:
Select-AzureRmSubscription -SubscriptionId {insert-subscription-id}
Below is the code that worked for me (regular dc regions). If it doesn't work, go to the Automation Account >> Modules >> Update Azure Modules.
$ClientSecret = ""
$ApplicationId = ""
$SubscriptionId = ""
#New PSCredential Object
$secpasswd = ConvertTo-SecureString $ClientSecret -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($ApplicationId , $secpasswd)
#Login to subscription
Login-AzureRmAccount -Credential $mycreds -SubscriptionId $SubscriptionId
#Export Database
New-AzureRmSqlDatabaseExport -ResourceGroupName "<RG>" -ServerName "<SQLSERVERNAME>" -DatabaseName "<DATABASENAME>" -StorageKeyType "StorageAccessKey" -StorageKey "<STRKEY>" -StorageUri "<URITOFILE>" -AdministratorLogin "<DBLOGIN>" -AdministratorLoginPassword "<DBPASS>"
Update
Maybe running with a Run As Account can be a workaround for the issue. Create one by navigating to the Azure Automation Account >> Account Settings >> Run As Accounts. Here's an example code.
# Authenticate to Azure with service principal and certificate, and set subscription
$connectionAssetName = "AzureRunAsConnection"
$conn = Get-AutomationConnection -Name $ConnectionAssetName
Add-AzureRmAccount -ServicePrincipal -Tenant $conn.TenantID -ApplicationId $conn.ApplicationId -CertificateThumbprint $conn.CertificateThumbprint -ErrorAction Stop | Write-Verbose
Set-AzureRmContext -SubscriptionId $conn.SubscriptionId -ErrorAction Stop | Write-Verbose
It looks like this is a known issue and I wasn't able to find a fix for that. But there are two workarounds:
Using a Hybrid Runnbook Worker (mentioned by Walter - MSFT)
Using a RunAsAccount with certificate credentials (mentioned by Bruno Faria)
It is important to specify the -Environment parameter. Otherwise I got the following exception:
Login-AzureRmAccount : AADSTS90038: Confidential Client is not
supported in Cross Cloud request.
Here is the code I am using to login to AzureGermanCloud (MCD) from an Azure Runbook hosted in NorthEurope:
$connectionAssetName = "AzureRunAsConnection"
$conn = Get-AutomationConnection -Name $ConnectionAssetName
Login-AzureRmAccount `
-ServicePrincipal `
-CertificateThumbprint $conn.CertificateThumbprint `
-ApplicationId $conn.ApplicationId `
-TenantId $conn.TenantID `
-Environment AzureGermanCloud
When you login your Azure account, you could use specified subscription id. You could try following script.
$subscriptionId=""
$tenantid=""
$clientid=""
$password=""
$userPassword = ConvertTo-SecureString -String $password -AsPlainText -Force
$userCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $clientid, $userPassword
Add-AzureRmAccount -TenantId $tenantid -ServicePrincipal -SubscriptionId $subscriptionId -Credential $userCredential -Environment 'AzureGermanCloud'

Azure credentials have not been set up or have expired

I have scheduled a PowerShell script to execute a pipeline in Azure.
Have generated the login script(ProfileContext.ctx) using Login-AzureRMAccount
Below is the code to schedule:
$path = "D:\ProfileContext.ctx"
Import-AzureRmContext -Path $path
$dfn = "salesprod"
$rgn = "sale-dw"
$df=Get-AzureRmDataFactory -ResourceGroupName $rgn -Name $dfn
$ISTstartdate = get-date
#Set Pipeline active period
$UTCstartdate = $ISTstartdate.touniversaltime().addminutes(5)
$UTCenddt = $UTCstartdate.AddHours(5)
$pipelinename = "SalesPipeline"
Set-AzureRmDataFactoryPipelineActivePeriod -ResourceGroupName $rgn -PipelineName $pipelinename -DataFactoryName $dfn -StartDateTime $UTCstartdate -EndDateTime $UTCenddt -Force
Above code works fine for 2 or 3 days but then I start getting below issue:
Your Azure credentials have not been set up or have expired, please run Login-AzureRMAccount to set up your Azure credentials.
At D:\RunPipeline.ps1
Below are the version nos:
PSVersion - 5.0.10586.117
Azure - 4.2.1
I resolved it by using below work around: This would auto login for me and then I can schedule without a context file:
$accountName = "pqr#xyz.com"
$password = ConvertTo-SecureString "mypwd" -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential($accountName, $password)
Login-AzureRmAccount -Credential $credential
Get-AzureRmResource
Add Joseph's answer. Your answer only works on Azure AD account, Microsoft account does not support non-interactive login. According to your scenario, I suggest you could use Service Principal, it is more safer and not leak your account information. What is Service Principal?
When you have an app or script that needs to access resources, you can
set up an identity for the app and authenticate the app with its own
credentials. This identity is known as a service principal.
You could refer to refer to this link to create a new service principal and give Contributor role. You could use the following command to login your subscription.
$subscriptionId=""
$tenantid=""
$clientid=""
$password=""
$userPassword = ConvertTo-SecureString -String $password -AsPlainText -Force
$userCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $clientid, $userPassword
Add-AzureRmAccount -TenantId $tenantid -ServicePrincipal -SubscriptionId $subscriptionId -Credential $userCredential
I came across with same issue today but after update Azure PowerShell Modules to the latest version, all good. You can do this while easily using Update-Module or just go ahead and use Install-Module AzureRm -Force.

Powershell Error Open Edx deployment on Azure

Why doest this script return diff error on Windows10 and Mac for the same Powershell Version?
Script executed:
Now, Azure PowerShell on Mac is in preview. It does not have full functions of Windows PowerShell. Parameter ServicePrincipalName is not supported on Mac now, so you get the error.
According to the error on Windows PowerShell. It seems that your application ID or password wrong. Do you check your them? You could use the following cmdlets to create service principal and logon Azure.
#login Azure
Login-AzureRmAccount
#create RM AD application
$app = New-AzureRmADApplication –DisplayName "<Your Application Display Name>" –HomePage "<http://YourApplicationHomePage>" –IdentifierUris "<http://YourApplicationUri>" –Password "<Your Password>"
#create a service principal for that application
New-AzureRmADServicePrincipal –ApplicationId $app.ApplicationId
#Assign that service principal a role.
New-AzureRmRoleAssignment –RoleDefinitionName Reader –ServicePrincipalName $app.ApplicationId
#Authenticating using a service principal
$pass = ConvertTo-SecureString "<Your Password>" -AsPlainText –Force
$cred = New-Object -TypeName pscredential –ArgumentList "<Your UserName>", $pass
Login-AzureRmAccount -Credential $cred -ServicePrincipal –TenantId <Your TenantId>
More information please refer to this link.
I found it. finally thanks to the collaboration of Microsoft support:
this line of code.
Set-AzureSubscription -SubscriptionName $AzureSubscriptionName| Out-Null
Is not correct. It should be:
Select-AzureRmSubscription -SubscriptionName $AzureSubscriptionName| Out-Null

Azure Credentials for build server

I'm having authentication headaches with Azure. I have a continuous build server running powershell scripts, and I'm getting messages like:
Your Azure credentials have not been set up or have expired, please run Login-AzureRMAccount to set up your Azure credentials.
I don't like having to login with my account on the build server. I suppose I could create another account just for building, but that will expire as well. Is there a better way of handling this?
You should not use Login-AzureRmAccount in your build/deploy scripts because this is an interactive login, but rather Add-AzureRmAccount instead.
Add-AzureRmAccount requires you create a service principal (application) in Azure AD and use its client id and secret/key to authenticate.
Here is a code snippet that you can use:
$clientID = "<the client id of your AD Application>"
$key = "<the key of your AD Application>"
$SecurePassword = $key | ConvertTo-SecureString -AsPlainText -Force
$cred = new-object -typename System.Management.Automation.PSCredential `
-argumentlist $clientID, $SecurePassword
Add-AzureRmAccount -Credential $cred -Tenant "xxxx-xxxx-xxxx-xxxx" -ServicePrincipal
To find out you tenant id (single subscription)
$tenant = (Get-AzureRmSubscription).TenantId
Find tenant id (multiple subscriptions)
$tenant = (Get-AzureRmSubscription -SubscriptionName "My Subscription").TenantId
