-## 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
