-
-    For more information on how to write a good commit message, take a look at
-    [How to Write a Git Commit Message](#{URL_GIT_COMMIT}).
-
-    Here is an example of a good commit message:
-
-        Reject ruby interpolation in externalized strings
-
-        When using ruby interpolation in externalized strings, they can't be
-        detected. Which means they will never be presented to be translated.
-
-        To mix variables into translations we need to use `sprintf`
-        instead.
-
-        Instead of:
-
-            _("Hello \#{subject}")
-
-        Use:
-
-            _("Hello %{subject}") % { subject: 'world' }
-
-    This is an example of a bad commit message:
-
-        updated README.md
-
-    This commit message is bad because although it tells us that README.md is
-    updated, it doesn't tell us why or how it was updated.

+
+## 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.

+### Create NAT Gateways
+
+Instances deployed in our private subnets need to connect to the internet for updates, but should not be reachable from the public internet. To achieve this, we'll make use of [NAT Gateways](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html) deployed in each of our public subnets:
+
+1. Navigate to the VPC dashboard and click on **NAT Gateways** in the left menu bar.
+1. Click **Create NAT Gateway** and complete the following:
+   1. **Subnet**: Select `gitlab-public-10.0.0.0` from the dropdown.
+   1. **Elastic IP Allocation ID**: Enter an existing Elastic IP or click **Allocate Elastic IP address** to allocate a new IP to your NAT gateway.
+   1. Add tags if needed.
+   1. Click **Create NAT Gateway**.
+
+Create a second NAT gateway but this time place it in the second public subnet, `gitlab-public-10.0.2.0`.

-This document describes how to operate Secure scanners offline.
+It is possible to run most of the GitLab security scanners when not

+
+This document describes how to operate Secure scanners in an air-gapped or offline envionment. These instructions also apply to
+self-managed installations that are secured, have security policies (e.g., firewall policies), or otherwise restricted from
+accessing the full internet. These instructions are designed for physically disconnected networks,
+but can also be followed in these other use cases.
+
+## Air-gapped (or offline) environments
+
+In this situation, the GitLab instance can be one or more servers and services that can communicate
+on a local network, but with no or very restricted access to the internet. Assume anything within
+the GitLab instance and supporting infrastructure (for example, a private Maven repository) can be
+accessed through a local network connection. Assume any files from the internet must come in through
+physical media (USB drive, hard drive, writeable DVD, etc.).
 
 ## Overview
 
-It is possible to run most of the GitLab security scanners when not
-connected to the internet, in what is sometimes known as an offline,
-limited connectivity, Local Area Network (LAN), Intranet, or "air-gap"
-environment.
-
-In this situation, the GitLab instance can be one, or more, servers and services running in a network that can talk to one another, but have zero, or perhaps very restricted access to the internet. Assume anything within the GitLab instance and supporting infrastructure (private Maven repository for example) can be accessed via local network connection. Assume any files from the internet must come in via physical media (USB drive, hard drive).

 GitLab scanners generally will connect to the internet to download the
 latest sets of signatures, rules, and patches. A few extra steps are necessary

+You must also ensure that your app has access to common package repositories
 that are not hosted on GitLab.com, such as npm, yarn, or rubygems. Packages
 from these repos can be obtained by temporarily connecting to a network or by
 mirroring the packages inside your own offline network.
 
+### Interacting with the vulnerabilities
+
+Once a vulnerability is found, you can interact with it. Read more on how to [interact with the vulnerabilities](../index.md#interacting-with-the-vulnerabilities).
+
+Please note that in some cases the reported vulnerabilities provide metadata that can contain external links exposed in the UI. These links might not be accessible within an air-gapped (or offline) environment.
+
 ### Scanner signature and rule updates
 
 When connected to the internet, some scanners will reference public databases
 for the latest sets of signatures and rules to check against. Without connectivity,
 this is not possible. Depending on the scanner, you must therefore disable
 these automatic update checks and either use the databases that they came
-with or manually update those databases.
