Chromium CDP

This example uses Chromium, a headless browser exposing a CDP (Chrome DevTools Protocol) websocket interface.

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.

   The unikraft CLI is the current standard, while kraft is the legacy version. Choose one of the CLIs below and only run the commands associated with it for the rest of this guide.

2. Clone the examples repository and cd into the examples/chromium-cdp/ directory:

   Code
   git clone https://github.com/unikraft-cloud/examples
   cd examples/chromium-cdp/

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

The UKC_TOKEN and UKC_METRO environment variables are only supported by the legacy CLI.

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 chromium-cdp-d0l6y and the address is https://spring-dream-p5wxwwl0.fra.unikraft.app. They're different for each run.

To query the service you need to use a CDP client. You can use the Python-based implementation in the test/ directory.

You can list information about the instance by running:

When done, you can remove the instance:
