+# .NET Core worker processing Azure Service Bus Queue scaled by KEDA
+A simple Docker container written in .NET that will receive messages from a Service Bus queue and scale via KEDA.
+
+The message processor will receive a single message at a time (per instance), and sleep for 2 second to simulate performing work. When adding a massive amount of queue messages, KEDA will drive the container to scale out according to the event source (Service Bus Queue).
+
+![Scenario](images/scenario.png)
+
+This sample is a refactored version of the one found at https://github.com/kedacore/sample-dotnet-worker-servicebus-queue.
+We Have removed all authentication options, and added AzureDefaultCredentials.
+The sample is also upgraded from Dotnet core 3.1 to Dotnet 8.
+
+## Configuring resources
+
+You need the following resources in Azure to run this example (these can be created in Azure Portal, or installed automatically with Terraform):
+
+- Azure ServiceBus Queue
+- Managed Identity 
+  - Assigned Roles:
+    - `Azure Service Bus Data Owner` role for your ServiceBus
+  - Federated credentials:
+    - Processor subject: `"system:serviceaccount:<YOUR-APP-NAME>-<YOUR-ENV-NAME>:processor-sa"`
+    - Web subject: `"system:serviceaccount:<YOUR-APP-NAME>-<YOUR-ENV-NAME>:web-sa"`
+    - Keda subject: `"system:serviceaccount:keda:keda-operator"`
+
+All Federated Credentials **Issuers** is the same, and can be found in the About page in the cluster https://console.radix.equinor.com/about (or in https://console.playground.radix.equinor.com/about for playground). It will look something like this: `https://northeurope.oic.prod-aks.azure.com/00000000-0000-0000-0000-000000000000/00000000-0000-0000-0000-000000000000/`.
+
+See [Radix Documentation](https://radix.equinor.com/guides/workload-identity/#configure-workload-identity-in-radix) for more details about working with Managed Identities and Workload Identity in Radx.
+
+### Configure resources with Terraform
+Configure `terraform.tf` and modify `resource_group_name`, `location`, `name`, and `radix_app_name` (minium).
+
+```shell
+terraform init
+# ...
+terraform apply
+# ...
+# Outputs:
+
+# client_id = "c2f17b62-7c2f-4541-acbc-22d7cfc66e0b"
+# endpoint = "https://<YOUR NAME>.servicebus.windows.net:443/"
+# queue_name = "orders"
+```
+
+### App Settings
+
+Configure `appsettings.json` in `./Radix.Samples.DotNet.Web`, `./Radix.Samples.DotNet.Processor` and `./Radix.Samples.DotNet.Generator`.
+
+## Development
+Start web server:
+```shell
+cd src/Radix.Samples.DotNet.Web; dotnet run
+```
+
+Start the processor:
+```shell
+cd src/Radix.Samples.Dotnet.OrderProcessor; dotnet run
+```
+
+Generate some events:
+```shell
+cd src/Radix.Samples.Dotnet.OrderGenerator; dotnet run
+# Let's queue some orders, how many do you want?
+# 2
+# Queuing order 719a7b19-f1f7-4f46-a543-8da9bfaf843d - A Hat for Reilly Davis
+# Queuing order 5c3a954c-c356-4cc9-b1d8-e31cd2c04a5a - A Salad for Savanna Rowe
+# That's it, see you later!
+```
+
+## Deployment
+
+Update Radixconfig with your ClientID and endpoint details and enjoy 🎉
+
+
+### Radix Config Trigger details:
+```yaml
+metadata:
+  name: <Your Radix App Name> # Change this!
+  components:
+
+    - name: web
+      horizontalScaling:
+        # defaults to using CPU scaling with 80% target utilization, and min 1 replica
+        maxReplicas: 3 
+
+    - name: processor
+      horizontalScaling:
+        maxReplicas: 10
+        minReplicas: 0
+        triggers:
+         - name: azuresb
+           azureServiceBus:
+             namespace: <AzureServiceBusNamespace> #.servicebus.windows.net
+             queueName: orders
+             messageCount: 2 # How many messages should each replica handle? 
+
+             # Workload Identity for KEDA to access service bus
+             authentication:
+               identity:
+                 azure:
+                   clientId: 00000000-0000-0000-0000-000000000000 # Replace with Client ID of your managed identity
+```
+
+
+### Terraform Keda details:
+
+To configure Keda, create a managed identity, and assign it a federated credential, like this if you are using Terraform:
+```terraform
+resource "azurerm_federated_identity_credential" "keda" {
+  audience            = ["api://AzureADTokenExchange"]
+  issuer              = local.radix_oidc_issuer_url # https://console.radix.equinor.com/about
+  name                = "keda"
+  resource_group_name = azurerm_servicebus_namespace.main.resource_group_name
+  subject             = "system:serviceaccount:keda:keda-operator" # RADIX Keda operator
+  parent_id           = azurerm_user_assigned_identity.main.id # Your managed identity that have access to the ServiceBus
+}
+```
+
+> ⚠️ Giving Keda access to your servicebus to count messages eables any other Radix Application to scale their apps based on messages in your queues.
+> 
+> Note: This does not give their app access to your ServiceBus, only the trigger to read the count of messages.
+
+## Cleanup
+To cleanup your resources run `terraform destroy` and delete your app in Radix
