@Marvin I'm setting up a push worker pool using azure container instances. I'm following the tutorial and I created the role and identity, but when I configure the ACI work pool on prefect, it asks me for a credential block with a password. Do I need to create a new principal service id with a password ?
m
To set up an Azure Container Instances (ACI) work pool in Prefect, you will need to provide a credential block. This credential block often requires a service principal with a password. Here's a summary of what you need to do: 1. Create a Service Principal: If you haven't done so already, you need to create an Azure service principal. This can be done using the Azure CLI with a command like:
Copy code
bash
   az ad sp create-for-rbac --name <your-service-principal-name> --role Contributor --scopes /subscriptions/<your-subscription-id>
This command will output details including an
appId
,
password
, and
tenant
. 2. Configure the Credential Block: In Prefect, when configuring your ACI work pool, you will need to input these credentials (specifically the
appId
and
password
) into the credential block. The
password
here refers to the client secret generated for the service principal. 3. Update the ACI Work Pool Configuration: Navigate to the Edit page of your ACI work pool in the Prefect UI and input the necessary details in the credential block. For more detailed steps, you can refer to the Prefect ACI Worker Guide. If you need further assistance with setting up or have any specific questions, feel free to ask!

@Marvin it seems I don't have access to create roles for subscriptions scope. Is there another scope that I can use that would work ?
m
If you don't have permissions to create roles at the subscription scope, you can create a service principal with a more limited scope. Here are some alternatives you might consider: 1. Resource Group Scope: You can create a service principal scoped to a specific resource group. This limits the permissions to only resources within that group. Use the following command:
Copy code
bash
   az ad sp create-for-rbac --name <your-service-principal-name> --role Contributor --scopes /subscriptions/<your-subscription-id>/resourceGroups/<your-resource-group-name>
2. Specific Resource Scope: If your operations are limited to specific resources, you can also scope the service principal to individual resources, though this is less common for broad tasks like managing container instances. 3. Collaboration: If you lack permissions to create roles, you may need to collaborate with someone in your organization who has the necessary permissions to create a service principal with the required scope. 4. Custom Roles: If Contributor access is too broad and you have the ability to create custom roles, you might consider creating a custom role with just the permissions you need and assigning it at a more limited scope. Remember to replace placeholders like
<your-service-principal-name>
,
<your-subscription-id>
, and
<your-resource-group-name>
with your actual values. If you have any more questions or need further assistance, feel free to ask!

@Marvin I get the following error on my flow run: MSI identity should not use ClientSecretCredential
m
The error "MSI identity should not use ClientSecretCredential" indicates a mismatch in the type of authentication being used. Managed Service Identity (MSI) should not be configured with a client secret. Instead, MSI uses Azure's identity services to authenticate. Here's how you can address this: 1. Use MSI for Authentication: Ensure that your Azure setup is using MSI for authentication. This involves assigning an MSI to your Azure resources and configuring Prefect to use this identity. 2. Configure Prefect to Use MSI: In your Prefect configuration, ensure that you're not using a client secret for authentication if you're intending to use MSI. Prefect should be set up to leverage the MSI directly. 3. Check Azure Configuration: Verify that your Azure Container Instances and other resources are correctly configured to use MSI. This typically involves enabling the MSI on the resource and ensuring it has the necessary permissions. If you are following the Prefect ACI Worker Guide, make sure to correctly set up the identity as per the guide's instructions. You can refer to the Prefect ACI Worker Guide for more detailed steps on setting up MSI with Prefect. If you need further assistance or have more questions, feel free to ask!

@Marvin I am actually following the Prefect ACI Worker Guide but the ACI work pool configuration on prefect cloud in Step 5 won't accept without an Azure secret block, and I don't know how to populate it
m
To set up an Azure secret block in Prefect, you need to provide the necessary credentials that Prefect will use to authenticate with Azure. Here's a concise guide on how to populate it: 1. Create an Azure Secret Block: In the Prefect UI, navigate to the Blocks page and create a new block. Select the Azure Secret block type. 2. Populate the Azure Secret Block: - Client ID: This is the application (client) ID of your Azure service principal. - Client Secret: The client secret associated with the service principal. - Tenant ID: The directory (tenant) ID of your Azure Active Directory. 3. Assign the Secret Block to Your Work Pool: Once the Azure secret block is created, you can assign it to your ACI work pool configuration in Prefect Cloud. If you encounter any issues or need further details, you can refer to the Prefect documentation or reach out for more specific help. Unfortunately, the direct link to the exact section wasn't available, but the steps above should guide you through the process.
