noVNC

This guide explains how to create and deploy a noVNC app, allowing you to access remote desktops through a web interface inside a modern browser.

Note: Anthropic's Computer Use Demo inspired this example.

To run this example, follow these steps:

1. Install the CLI. Use the unikraft CLI or the legacy kraft CLI. You need a BuildKit builder. The easiest way to get one is via Docker. Alternatively, you can also directly set up and use BuildKit, see the quick start.

2. Clone the examples repository and cd into the examples/novnc-browser directory:

Code
git clone https://github.com/unikraft-cloud/examples
cd examples/novnc-browser/

Make sure to log into Unikraft Cloud and pick a metro close to you. This guide uses fra (Frankfurt, 🇩🇪):

When done, invoke the following command to deploy this app on Unikraft Cloud:

The output shows the instance address and other details:

In this case, the instance name is vnc-browser and the address is https://weathered-fog-y5jjmwfd.fra.unikraft.app. The name was preset, but the address is different for each run. Enter the provided address into your browser of choice to access the remote desktop interface.

Use curl to query the Unikraft Cloud instance:

Code
curl https://weathered-fog-y5jjmwfd.fra.unikraft.app

Code
Hello, World!

You can list information about the instance by running:
