+
+This guide takes you through the steps to get Node-RED running on an Google
+Cloud Platform (GCP) - Compute Engine.
+
+You can use the Node Package Manager (`npm`) to install Node-RED on any
+environment that has a Node.JS runtime. For GCP, this includes Compute Engine,
+Google Kubernetes Engine (GKE), Cloud Run, Cloud Shell as well as other GCP
+environments.
+
+There’s also a publically available Docker image, which is what we’ll use for
+this example.
+
+#### Create a Compute Engine instance
+
+1. Log in to [GCP](https://console.cloud.google.com/)
+
+2. Open `Compute Engine` and create a new one.
+
+3. Check the label `Deploy a container image to this VM instance` and enter
+   `nodered/node-red` as the name of the container image.
+
+4. Leave all the other settings as their defaults and proceed to complete.
+
+Once the VM has started your Node-RED is running.
+In the console you can find your instance's IP address.
+
+#### Firewall setup
+
+Node-RED listens on port `1880`. The default VPC network firewall deliberately
+restricts incoming requests which means that requests to port 1880 will be
+**denied**.
+
+The next step will be to allow ingress traffic to the Node-RED instance.
+
+1. [Create](https://console.cloud.google.com/appengine/firewall/create) a new
+   firewall rule.
+
+2. Enter a `Priority` (e.g. 1).
+
+3. Specify in `Action on match` the `allow` option to allow ingress.
+
+4. In `IP range` define the IP addresses which should have access. You can also
+   put `*` for allowing ingress from every IP.
+
+5. Save the rule.
+
+#### Work with Node-RED
+
+After you created the Compute Engine and added the firewall rule you have access to
+the Node-RED instance via the `IP address` from the Compute instance and port `1880`.
