Playwright (Chromium) with Python FastAPI

Playwright is a framework for web testing and Automation.

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/python-playwright-chromium/ directory:

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

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 python-playwright-chromium-m6k3p and the address is https://young-night-kq8bv2mx.fra.unikraft.app. They're different for each run.

The command will deploy the files in the current directory. It results in the creation of a remote web-based service for creating PNG screenshots of remote pages.

Use the ?page=<REMOTE_URL> to point the service to the remote page to screenshot. Query the service using commands such as:

Code
curl "https://<NAME>.<METRO>.unikraft.app/?page=https://google.com" -o ss-google.png
curl "https://<NAME>.<METRO>.unikraft.app/?page=https://github.com" -o ss-github.png

You can list information about the instance by running:

When done, you can remove the instance:
