I have created an automated Service Principal from the service requests on Azure Devops with sufficient permissions. Now, when I am trying to create an artifact which is an ML model (registered) it is not auto populating the registered models and resulting in an error.
I am using a free trial Azure account and attempting to implement CI CD for ML. I turned my firewall off and attempted as well but still the issue persists.
It appears that the Service Principal is not assigned the role in the appropriate subscription.
You need to grant the service principal Azure subscription access permission:
Login Azure portal->All service->Subscriptions->click your subscription->Access control(IAM)->Add role assignment->assign the correct role to your service principal
Refer to Use the portal to create an Azure AD application and service principal that can access resources and Assign Azure roles using the Azure portal for details.

Stuff in Azure are secured with Service Accounts. In order for me to see stuff I need to download the Service Account certificate and then log in via the Azure CLI using the extracted certificate and the Service Account Application Id. So now I can see everything the Service Account can see, great. But it is a pain in the neck and slow. So my question: Can I use the same certificate and credentials to log into the Azure Portal website so I can browse around using the web browser instead?
Using a Service Principal for interactive logins to the Azure Portal is not possible - which is by design. In order to be able to see the same resources as the Service Principal through the Azure Portal, you would require a user account that holds the Azure RBAC Reader role against those resources that are in scope of the Service Principal role assignments.
As you mentioned performance being an issue with using the Service Principal login, you could try Azure Resource Graph queries. These are supported by Azure CLI, Azure PowerShell as well as all the major Azure SDK's. Obviously, this won't bring you the visual experience like the Azure Portal but might resolve the performance piece maybe.
However, requesting/creating a user account that has the corresponding RBAC roles assigned would be the only way to allow you to see the resources through the Azure Portal.
I want to use the "ARM template deployment" task in Azure pipelines, and for this, I need to set up a service connection of type "Azure Resource Manager connection". So I head over to the Service connections pane. And it turns out that in order to configure this service connection, one of the authentication methods is using a service principal.
So I'v tried learning a little bit about service principals, and what I've understood so far is as such:
App registration is the process of registering applications which I want to delegate identity and access management to Azure AD for. A service principal is a concrete instantiation of the Application object that I create in my Azure AD tenant.
I didn't yet get my head around all these concepts well enough, but what I don't even start to understand is what does all that have to do with an authentication method for a Azure Resource Manager service connection in Azure DevOps??
Can someone please clear up the fog for me?
Azure Devops is not integrated with Azure portal by any means. Also, Azure Devops is not a trusted service even by Microsoft itself.
The Service Connection will help you to establish a connection between Azure portal and Azure Devops. Here, the service principal acts like a user account to establish the connection.
First of all, for using the task "ARM template deployment" in Azure DevOps pipeline, this task is used to deploy Azure Resource Manager templates at resource group deployment scope, subscription deployment scope and management group deployment scopes. The task is also used to create or update a resource group in Azure.
And you should select your Azure Resource and specified subscription which are the prerequisites of the task usage, then for connecting to a subscription which is associated with an Azure Active Directory tenant when building pipeline, it is needed to create a Service connection to help work between pipeline and connect to Azure Subscription. For more info, you can refer to doc:
Azure DevOps Connection Services. And you should also login authenticate via service principle instead of user, it is just like Azure log in.
Besides, you can also manage your Azure subscriptions at scale with management groups via this doc: Organize subscriptions into management groups and assign roles to users for Microsoft Defender for Cloud | Microsoft Learn .
According this when you create an Azure Resource Manager service connection to a certain Resource Group, Azure DevOps connects with Azure Active Directory (Azure AD) and creates an app registration with a secret that's valid for two years.
Well, what exactly are the permissions given to this app registration over the Resource Group? Same than the account which is creating the service connection?
When you create a automated Azure Resource Manager Service connection in Azure Devops, it will automaticlly create a service principal in Azure Active Directory(Named: Orgname-projectname-SubscriptionID).
You could navigate to Azure Portal -> Azure Active Directory -> App registrations.
When using this automatic service connection in azure devops, azure sources are operated through this service principal instead of the account which is creating the service connection.
This service principal has the Contributor role in Azure Resource Group.
Grants full access to manage all resources, but does not allow you to assign roles in Azure RBAC, manage assignments in Azure Blueprints, or share image galleries.
You can search for the service principal name in Resource Group -> Access control to check its permissions
what exactly are the permissions given to this app registration over the Resource Group?
It is a Contributor role, also did a quick test for you.
Same than the account which is creating the service connection?
No, the account needs to be the Owner of the subscription, otherwise it will not have the permission to assign the role to the AD App i.e. service principal.
I am deploying a standard ASP.NET MVC application to an Azure App Service using a VSTS build and release definition. The VSTS instance and the target Azure subscription are on separate Azure accounts/subscriptions so we have create a Azure AD application and Service Principal account to authorize the deployment.
When adding the Service Principal account to the subscription, it wants us to assign a role.
What is the best and least privileged role that can be used to deploy the site?
When add Azure Resource Manager Service Endpoint, it mentions:
A new Azure Service Principal will be created and assigned with
"Contributor" role, having access to all the resources in the selected
subscription.
So, the Contributor role is better.
On the other hand, to configure Azure RM service endpoint, you must be a member of the Global Admin role in the directory. More information: Insufficient privileges to complete the operation.
We have a VSTS Azure Resource Manager Service Endpoint that uses a Service Principal to connect to Azure. This service principal was created manually. I was wondering if this service principle is impacted by the Azure AD signing key roll over and whether it will handle it automatically.
If you are using a service principal created through VSTS, there shouldn't be a problem. If it's created another way, you'll want to check this article from the Azure team about the rollover.
