+:::important Container Execution Requirements
+The Azure Function Deploy step requires a containerized execution environment:
+
+- If you select the **Basic** deployment strategy, Harness automatically adds a container Step Group with the Azure Function Deploy step inside it.
+
+- If you select the **Custom** deployment strategy, you need to manually:
+  1. Add a Step Group to your pipeline
+  2. Enable the **Container** option in the Step Group
+  3. Configure the Step Group to use your Kubernetes connector
+  4. Add the Azure function Deploy step inside this Step Group
+
+Failure to run the step in a containerized execution context will likely result in deployment failures.
