DIFFERENCE BETWEEN BOTH USE CASES:-
In Use Case 1, PAT is prompted as User Input during script execution.
In Use Case 2, PAT is set as Environment variable so that it is not prompted as User Input during script execution.

Now, let me explain the script, part by part for better understanding.

VARIABLES:-

USE CASE 1:-

##############
# VARIABLES:-
############## 
$spiname = "AM-Test-SPI-100"
$rbac = "Contributor"
$devopsOrg = "https://dev.azure.com/arindammitra0251/"
$devopsPrj = "AMCLOUD"
$subsID = "210e66cb-55cf-424e-8daa-6cad804ab604"
$subsName = "AM-PROD-VS"
$tenantID = "20516b3d-42af-4bd4-b2e6-e6b4051af72a"
$kv = "ampockv"

Enter fullscreen mode Exit fullscreen mode

USE CASE 2:-

##############
# VARIABLES:-
############## 
$spiname = "AM-Test-SPI-200"
$rbac = "Contributor"
$pat = "<Provide your own PAT>"
$devopsOrg = "https://dev.azure.com/arindammitra0251/"
$devopsPrj = "AMCLOUD"
$subsID = "210e66cb-55cf-424e-8daa-6cad804ab604"
$subsName = "AM-PROD-VS"
$tenantID = "20516b3d-42af-4bd4-b2e6-e6b4051af72a"
$kv = "ampockv"

Enter fullscreen mode Exit fullscreen mode
NOTE:-
Please change the values of the variables accordingly.
The entire script is build using Variables. No Values are Hardcoded. Changing the values of the variables should help you execute the script seamlessly.

NOW ITS TIME TO TEST

TEST CASES:-
TEST CASE FOR USE CASE #1: PAT AS USER INPUT:-
Service Principal has been created. Application ID and Secret has been Stored in Key Vault. "Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.
As Observed, the script is now waiting for User Input PAT.
Image description
After providing the correct PAT, script executed successfully.
Image description
Image description
Service Principal (with secret) created successfully.
Image description
Application ID and Secret of Service Principal has been stored in Key Vault.
Image description
"Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.
Image description
Azure DevOps Service Connection has been created successfully with the newly created Service Principal.
Image description
Azure DevOps Service Connection Verification is successful.
Image description
TEST CASE FOR USE CASE #2: PAT AS ENVIRONMENT VARIABLE:-
Service Principal has been created. Application ID and Secret has been Stored in Key Vault. "Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.
As Observed, No PAT is prompted during script execution.
Image description
Image description
Image description
Service Principal (with secret) created successfully.
Image description
Application ID and Secret of Service Principal has been stored in Key Vault.
Image description
"Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.
Image description
Azure DevOps Service Connection has been created successfully with the newly created Service Principal.

I wrote a similar script in the past but found when running the script in one go, I needed about 20 second of sleep after creation of service principle to ensure it was fully created behind the scenes because otherwise the creation of the service connection sometimes failed.

Hi @cbergmeister, I did not experience any such behavior while I was testing it. I normally do a rigorous testing before producing it in my Github.

But the Idea is not bad. Putting your Script in Sleep for few seconds can always reduce the chances of failure of your script. Proactive measure to make it less error prone.

The Initial idea was to automate it with Az DevOps , but somehow could not make it work .
All the things which I tried to make it work are mentioned in my Github.
I then raised an Github Issue, Still waiting for Microsoft to provide a solution.

Cheers, Arindam
