+#### Access the UI of a Prometheus managed application in Kubernetes
+
+You can connect directly to Prometheus, and view the Prometheus user interface, when
+using a Prometheus managed application in Kubernetes:
+
+1. Find the name of the Prometheus pod in the user interface of your Kubernetes
+   provider, such as GKE, or by running the following `kubectl` command in your
+   terminal:
+
+   ```shell
+   kubectl get pods -n gitlab-managed-apps | grep 'prometheus-prometheus-server'
+   ```
+
+   The command should return a result like the following example, where
+   `prometheus-prometheus-server-55b4bd64c9-dpc6b` is the name of the Prometheus pod:
+
+   ```plaintext
+   gitlab-managed-apps  prometheus-prometheus-server-55b4bd64c9-dpc6b  2/2  Running  0  71d
+   ```
+
+1. Run a `kubectl port-forward` command. In the following example, `9090` is the
+   Prometheus server's listening port:
+
+   ```shell
+    kubectl port-forward prometheus-prometheus-server-55b4bd64c9-dpc6b 9090:9090 -n gitlab-managed-apps
+   ```
+
+   The `port-forward` command forwards all requests sent to your system's `9090` port
+   to the `9090` port of the Prometheus pod. If the `9090` port on your system is used
+   by another application, you can change the port number before the colon to your
+   desired port. For example, to forward port `8080` of your local system, change the
+   command to:
+
+   ```shell
+   kubectl port-forward prometheus-prometheus-server-55b4bd64c9-dpc6b 8080:9090 -n gitlab-managed-apps
+   ```
+
+1. Open `localhost:9090` in your browser to display the Prometheus user interface.
+
+#### Script access to Prometheus
+
+You can script the access to Prometheus, extracting the name of the pod automatically like this:
+
+```shell
+POD_INFORMATION=$(kubectl get pods -n gitlab-managed-apps | grep 'prometheus-prometheus-server')
+POD_NAME=$(echo $POD_INFORMATION | awk '{print $1;}')
+kubectl port-forward $POD_NAME 9090:9090 -n gitlab-managed-apps
+```
+
