Deploy Service Fabric application with a User-Assigned Managed Identity

To deploy a Service Fabric application with managed identity, the application needs to be deployed through Azure Resource Manager, typically with an Azure Resource Manager template. For more information on how to deploy Service Fabric application through Azure Resource Manager, see Manage applications and services as Azure Resource Manager resources.

Note

Applications which are not deployed as an Azure resource cannot have Managed Identities.

Service Fabric application deployment with Managed Identity is supported with API version "2019-06-01-preview". You can also use the same API version for application type, application type version and service resources.

User-Assigned Identity

To enable application with User-Assigned identity, first add the identity property to the application resource with type userAssigned and the referenced user-assigned identities. Then add a managedIdentities section inside the properties section for the application resource which contains a list of friendly name to principalId mapping for each of the user-assigned identities. For more information about User Assigned Identities see Create, list or delete a user-assigned managed identity.

Application template

To enable application with User Assigned identity, first add identity property to the application resource with type userAssigned and the referenced user assigned identities, then add a managedIdentities object inside the properties section that contains a list of friendly name to principalId mapping for each of the user assigned identities.

{
  "apiVersion": "2019-06-01-preview",
  "type": "Microsoft.ServiceFabric/clusters/applications",
  "name": "[concat(parameters('clusterName'), '/', parameters('applicationName'))]",
  "location": "[resourceGroup().location]",
  "dependsOn": [
    "[concat('Microsoft.ServiceFabric/clusters/', parameters('clusterName'), '/applicationTypes/', parameters('applicationTypeName'), '/versions/', parameters('applicationTypeVersion'))]",
    "[resourceId('Microsoft.ManagedIdentity/userAssignedIdentities/', parameters('userAssignedIdentityName'))]"
  ],
  "identity": {
    "type" : "userAssigned",
    "userAssignedIdentities": {
        "[resourceId('Microsoft.ManagedIdentity/userAssignedIdentities/', parameters('userAssignedIdentityName'))]": {}
    }
  },
  "properties": {
    "typeName": "[parameters('applicationTypeName')]",
    "typeVersion": "[parameters('applicationTypeVersion')]",
    "parameters": {
    },
    "managedIdentities": [
      {
        "name" : "[parameters('userAssignedIdentityName')]",
        "principalId" : "[reference(resourceId('Microsoft.ManagedIdentity/userAssignedIdentities/', parameters('userAssignedIdentityName')), '2018-11-30').principalId]"
      }
    ]
  }
}

In the example above the resource name of the user assigned identity is being used as the friendly name of the managed identity for the application. The following examples assume the actual friendly name is "AdminUser".

Application package

  1. For each identity defined in the managedIdentities section in the Azure Resource Manager template, add a <ManagedIdentity> tag in the application manifest under Principals section. The Name attribute needs to match the name property defined in the managedIdentities section.

    ApplicationManifest.xml

      <Principals>
        <ManagedIdentities>
          <ManagedIdentity Name="AdminUser" />
        </ManagedIdentities>
      </Principals>
    
  2. In the ServiceManifestImport section, add a IdentityBindingPolicy for the service that uses the Managed Identity. This policy maps the AdminUser identity to a service-specific identity name that needs to be added into the service manifest later on.

    ApplicationManifest.xml

      <ServiceManifestImport>
        <Policies>
          <IdentityBindingPolicy ServiceIdentityRef="WebAdmin" ApplicationIdentityRef="AdminUser" />
        </Policies>
      </ServiceManifestImport>
    
  3. Update the service manifest to add a ManagedIdentity inside the Resources section with the name matching the ServiceIdentityRef in the IdentityBindingPolicy of the application manifest:

    ServiceManifest.xml

      <Resources>
        ...
        <ManagedIdentities DefaultIdentity="WebAdmin">
          <ManagedIdentity Name="WebAdmin" />
        </ManagedIdentities>
      </Resources>
