+# Containerize a Native Executable and Run in a Container
+
+You can find the steps to run this demo on [the website](https://www.graalvm.org/latest/reference-manual/native-image/guides/containerise-native-executable-and-run-in-docker-container/).
+
+## Measure the Performance of the Application and Metrics
+
+The Spring Actuator dependency is added to the project, along with support for Prometheus.
+If you want to test the performance of either the JVM version, or the native executable version of the application, you can make use of the Prometheus support.
+If you are hosting the application locally, it is available on port 8080:
