CODE REPOSITORY:-
{% github arindam0310018/15-Nov-2022-DevOpsCLI__Create-Service-Connection %}

BELOW FOLLOWS THE CODE SNIPPET:-

USE CASE #1:-

CREATE AZURE DEVOPS SERVICE CONNECTION WITH PAT AS USER INPUT (Create-DevOps-Service-Connection-Prompt-PAT.ps1):-

##############
# VARIABLES:-
############## 
$spiname = "AM-Test-SPI-100"
$rbac = "Contributor"
$devopsOrg = "https://dev.azure.com/arindammitra0251/"
$devopsPrj = "AMCLOUD"

##############
# CORE SCRIPT:-
############## 

# Create Service Principal and Store Secret in a variable:-
$spipasswd = az ad sp create-for-rbac -n $spiname --query "password" -o tsv

# Query the Application ID of the Service Principal and Store it in a variable:-
$spiID = az ad sp list --display-name $spiname --query [].appId -o tsv

# Store the Service Principal Application ID and Secret in Key Vault:-
az keyvault secret set --name $spiname-id --vault-name $kv --value $spiID
az keyvault secret set --name $spiname-passwd --vault-name $kv --value $spipasswd

# Assign the Service Principal, "Contributor" RBAC on Subscription Level:-
az role assignment create --assignee "$spiID" --role "$rbac" --scope "/subscriptions/$subsID"

#Set Service Principal Secret as an Environment Variable for creating Azure DevOps Service Connection:-
$env:AZURE_DEVOPS_EXT_AZURE_RM_SERVICE_PRINCIPAL_KEY=$spipasswd

# Perform DevOps Login. It will Prompt for PAT:-
az devops login

# Set Default DevOps Organisation and Project:-
az devops configure --defaults organization=$devopsOrg project=$devopsPrj

# Create DevOps Service Connection:-
az devops service-endpoint azurerm create --azure-rm-service-principal-id $spiID --azure-rm-subscription-id $subsID --azure-rm-subscription-name $subsName --azure-rm-tenant-id $tenantID --name $spiname --org $devopsOrg --project $devopsPrj

# Grant Access to all Pipelines to the Newly Created DevOps Service Connection:-
$srvEndpointID = az devops service-endpoint list --query "[?name=='$spiname'].id" -o tsv
az devops service-endpoint update --id $srvEndpointID --enable-for-all

USE CASE #2:-

CREATE AZURE DEVOPS SERVICE CONNECTION WITH PAT AS ENVIRONMENT VARIABLE (Create-DevOps-Service-Connection-Without-Prompting-PAT.ps1):-

##############
# VARIABLES:-
############## 
$spiname = "AM-Test-SPI-200"
$rbac = "Contributor"
$pat = "<Provide your own PAT>"
$devopsOrg = "https://dev.azure.com/arindammitra0251/"
$devopsPrj = "AMCLOUD"

$tenantID = "20516b3d-42af-4bd4-b2e6-e6b4051af72a"
$kv = "ampockv"

##############
# CORE SCRIPT:-
############## 

# Create Service Principal and Store Secret in a variable:-
$spipasswd = az ad sp create-for-rbac -n $spiname --query "password" -o tsv

# Query the Application ID of the Service Principal and Store it in a variable:-

# Store the Service Principal Application ID and Secret in Key Vault:-
az keyvault secret set --name $spiname-id --vault-name $kv --value $spiID
az keyvault secret set --name $spiname-passwd --vault-name $kv --value $spipasswd

# Assign the Service Principal, "Contributor" RBAC on Subscription Level:-

# Set Default DevOps Organisation and Project:-
az devops configure --defaults organization=$devopsOrg project=$devopsPrj

# Create DevOps Service Connection:-
az devops service-endpoint azurerm create --azure-rm-service-principal-id $spiID --azure-rm-subscription-id $subsID --azure-rm-subscription-name $subsName --azure-rm-tenant-id $tenantID --name $spiname --org $devopsOrg --project $devopsPrj

# Grant Access to all Pipelines to the Newly Created DevOps Service Connection:-
$srvEndpointID = az devops service-endpoint list --query "[?name=='$spiname'].id" -o tsv
az devops service-endpoint update --id $srvEndpointID --enable-for-all

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"

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"

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.

CORE SCRIPT:-

Create Service Principal and Store Secret in a variable:-

$spipasswd = az ad sp create-for-rbac -n $spiname --query "password" -o tsv

Query the Application ID of the Service Principal and Store it in a variable:-

$spiID = az ad sp list --display-name $spiname --query [].appId -o tsv

Store the Service Principal Application ID and Secret in Key Vault:-

az keyvault secret set --name $spiname-id --vault-name $kv --value $spiID
az keyvault secret set --name $spiname-passwd --vault-name $kv --value $spipasswd

Assign the Service Principal, "Contributor" RBAC on Subscription Level:-

az role assignment create --assignee "$spiID" --role "$rbac" --scope "/subscriptions/$subsID"

Set Service Principal Secret as an Environment Variable for creating Azure DevOps Service Connection:-

$env:AZURE_DEVOPS_EXT_AZURE_RM_SERVICE_PRINCIPAL_KEY=$spipasswd

Perform DevOps Login. It will Prompt for PAT Token:-

az devops login

OR

Set PAT as an environment variable for DevOps Login:-

$env:AZURE_DEVOPS_EXT_PAT = $pat

Set Default DevOps Organisation and Project:-

az devops configure --defaults organization=$devopsOrg project=$devopsPrj

Create DevOps Service Connection:-

az devops service-endpoint azurerm create --azure-rm-service-principal-id $spiID --azure-rm-subscription-id $subsID --azure-rm-subscription-name $subsName --azure-rm-tenant-id $tenantID --name $spiname --org $devopsOrg --project $devopsPrj

Grant Access to all Pipelines to the Newly Created DevOps Service Connection:-

$srvEndpointID = az devops service-endpoint list --query "[?name=='$spiname'].id" -o tsv
az devops service-endpoint update --id $srvEndpointID --enable-for-all

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.

After providing the correct PAT, script executed successfully.


Service Principal (with secret) created successfully.

Application ID and Secret of Service Principal has been stored in Key Vault.

"Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.

Azure DevOps Service Connection has been created successfully with the newly created Service Principal.

Azure DevOps Service Connection Verification is successful.

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.



Service Principal (with secret) created successfully.

Application ID and Secret of Service Principal has been stored in Key Vault.

"Contributor" RBAC has been assigned to the newly created Service Principal on Subscription Level.

Azure DevOps Service Connection has been created successfully with the newly created Service Principal.

Azure DevOps Service Connection Verification is successful.

Hope You Enjoyed the Session!!!
