Configure managed identity support for a new Service Fabric cluster

  • Article

To use Managed identities for Azure resources in your Service Fabric applications, first enable the Managed Identity Token Service on the cluster. This service is responsible for the authentication of Service Fabric applications using their managed identities, and for obtaining access tokens on their behalf. Once the service is enabled, you can see it in Service Fabric Explorer under the System section in the left pane, running under the name fabric:/System/ManagedIdentityTokenService next to other system services.

Note

Service Fabric runtime version 6.5.658.9590 or higher is required to enable the Managed Identity Token Service.

Enable the Managed Identity Token Service

To enable the Managed Identity Token Service at cluster creation time, add the following snippet to your cluster Azure Resource Manager template:

"fabricSettings": [
    {
        "name": "ManagedIdentityTokenService",
        "parameters": [
            {
                "name": "IsEnabled",
                "value": "true"
            }
        ]
    }
]

Errors

If the deployment fails with this message, it means the cluster is not on the required Service Fabric version (the minimum supported runtime is 6.5 CU2):

{
    "code": "ParameterNotAllowed",
    "message": "Section 'ManagedIdentityTokenService' and Parameter 'IsEnabled' is not allowed."
}
