I've configured Azure DevOps with a Service Principal to access one specific resource group. I was expecting Azure DevOps will only be able to deploy to resources under this group but that doesn't seem to be the case. I am able to connect agents from other resource groups and then deploy to them without any issue.
What's the point of configuring Service Principal in 'Azure DevOps' if the agent can bypass all permissions?
Configuration:
Azure Portal
1. Created AD in Azure Portal. Created App under AD with client secret.
2. Granted 'contributor' role to App created in Step-1 with resource group scope.
3. Created two resource groups - RG1 and RG2 with one VM in each.
4. Granted role assignment to App created in step-1 for RG1 only. RG2 has no role assignments.
Azure DevOps
5. Connect Azure DevOps organization with Portal using AD connect.
6. Created service connection by going to Projects-> Service Principal(SP) -> Azure Resource Manager with Service Principal credentials (see step-1 above).
7. Created new pipeline and deployment group. Copied the deployment group agent code and ran it on both VMs in RG1 and RG2.
Actual Result:
Both VMs connected fine as targets under deployment group.
Pipeline was able to deploy successfully to both VMs.
Even if no service connections exist, pipelines are able to deploy to VMs
Expected Result:
Only VM under RG1 should connect based on RBAC.
Pipeline should only be able to deploy to VM under RG1 and not RG2.
Pipelines shouldn't be able to deploy if service connections are not defined.
Workaround: Maybe installing this extension ( https://github.com/maikvandergaag/msft-extensions/wiki/Azure-RBAC ) would help but I was trying to avoid it if possible.
I believe your understanding on RBAC applies the Azure resources and the VM Resources. But you have already override the permission by installing the Deployment agent into the VM.
In the IAAS scenario, you have already granted permission using the deployment agent.
In the PAAS Scenario, RBAC will be adhered because you will be using service end point.

I have one problem with my Azure. I created build pipeline, and now i want to set up relase pipeline. I choosen Deploy App service, where is located my app service with subsription and resource group..
In Azure subsription dropdown I choose my subsription, it is listed.. but I need to authorize myself. I click then on Authorize and I get this error..
Error(s):
Service connection creation operation failed
Error: Service connection with name Microsoft Partner Network (subscription number) already exists. Only a user having Administrator/User role permissions on service connection Microsoft Partner Network (subsription number ) can see it.
I guess it is problem with authorisation, but I cant figure what is problem. I have privileges for my resource group.
The error indicates that within Azure DevOps a service connection with the name 'Microsoft Partner Network' already exists and that you do not have permissions to update/edit it. The permissions are actually needed within the Azure DevOps Project or Organization and are separate from Azure Resource Manager RBAC permissions such as are assigned to resource groups.
See Service Connection security roles for the requires role and references to managing project roles in Azure DevOps
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 .
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.
I am using Azure Devops Pipelines. In my CI yaml and calling a powershell script. Within Powershell i am reading details of an existing resource say storage account sitting in subscription X, and creating an exact replica in subscription Y. We have created a Service connection using service principal of X in Azure devops and are using in our CI pipeline. Not aware of how to include Y Service Principal so that resource can be created in Y subscription.
Anything can be handled at Azure side? Please suggest the way.
Im not seeing AKS from DevOps. Im trying to create a pipeline but AKS is not showing.
First of all, I created a service connection --> Azure Resource Manager --> Service Principal (Manual)
I have been working this way and I see all my AKS. I have a problem with this new one.
error
I dont know where is the problem. In DevOps I can see all my AKS except this new one
Any ideas to check?
In your Azure DevOps project navigate to Project Settings > Service Connections and select your Service Connection to Azure which will look something like this:
Depending on how your Service Principal was set up you may be able to browse to it directly in the Azure Portal by clicking the Manage Service Principal link. There are other ways to set up a Service Connection and the method to find the Service Principal in the Azure Portal will differ, checkout the documentation here. Make a note of the Display Name for your Service Principal.
In the Azure Portal navigate to your AKS resource then navigate to the Access Control (IAM) blade and click Role Assignments. Check what Roles the Azure AD Service Principal for your Azure DevOps Service Connection has been assigned, it will need at least Contributor to make changes to your AKS cluster.
You can use the verify connection link on the Edit service connection page to verify your connection information and check whether the Grant access permission to all pipelines option is checked.
In addition,here is a document on Troubleshoot Azure Resource Manager service connections you can refer to.
