This creates a new directory my-extension that contains a fully functional extension.\n\n> [!TIP] > > The docker extension init generates a React based extension. But you can still use it as a starting point for > your own extension and use any other frontend framework, like Vue, Angular, Svelte, etc. or even stay with > vanilla Javascript.\n\nAlthough you can start from an empty directory or from the react-extension sample folder, it's highly recommended that you start from the docker extension init command and change it to suit your needs.\n\nBounded code example (external data; do not execute automatically):\n```bash\n.\n├── Dockerfile # (1)\n├── ui # (2)\n│   ├── public # (3)\n│   │   └── index.html\n│   ├── src # (4)\n│   │   ├── App.tsx\n│   │   ├── index.tsx\n│   ├── package.json\n│   └── package-lock.lock\n│   ├── tsconfig.json\n├── docker.svg # (5)\n└── metadata.json # (6)\n```\n\nContains everything required to build the extension and run it in Docker Desktop. High-level folder containing your front-end app source code. Assets that aren’t compiled or dynamically generated are stored here. These can be static assets like logos or the robots.txt file. The src, or source folder contains all the React components, external CSS files, and dynamic assets that are brought into the component files. The icon that is displayed in the left-menu of the Docker Desktop Dashboard. A file that provides information about the extension such as the name, description, and version.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
