# Astro

> Deploy an Astro application to Magic Containers

This guide walks you through building and deploying an Astro application to Magic Containers with GitHub Container Registry. You'll need:

* A GitHub account for source code and container registry

<Tip>
  Don't have a bunny.net account yet? [Sign up](https://dash.bunny.net/auth/register) and enable Magic Containers to get started.
</Tip>

## Create the Astro app

Create a new Astro project:

```bash theme={null}
npm create astro@latest app-astro
cd app-astro
```

### Add the Node adapter

Astro requires an adapter for server-side rendering. Install the Node adapter:

```bash theme={null}
npx astro add node
```

This updates your `astro.config.mjs` to include the adapter:

```javascript astro.config.mjs theme={null}
import { defineConfig } from "astro/config";
import node from "@astrojs/node";

export default defineConfig({
  output: "server",
  adapter: node({
    mode: "standalone",
  }),
});
```

### Create an API route

Create a simple endpoint to test the deployment:

```typescript src/pages/index.json.ts theme={null}
import type { APIRoute } from "astro";

export const GET: APIRoute = () => {
  return new Response(JSON.stringify({ message: "Hello from Bunny 🐰" }));
};
```

## Run locally

Start the development server:

```bash theme={null}
npm run dev
```

Visit [http://localhost:4321](http://localhost:4321) in your browser, or test the API route:

```bash theme={null}
curl http://localhost:4321/index.json
```

## Create the Dockerfile

```dockerfile Dockerfile theme={null}
FROM node:22-alpine AS base
WORKDIR /app
COPY package*.json ./

FROM base AS deps
RUN npm install

FROM deps AS build
COPY . .
RUN npm run build

FROM base AS runtime
COPY package*.json ./
RUN npm install --omit=dev
COPY --from=build /app/dist ./dist

ENV HOST=0.0.0.0
ENV PORT=80
EXPOSE 80

CMD ["node", "./dist/server/entry.mjs"]
```

## Build and push to GitHub Container Registry

<Tabs>
  <Tab title="GitHub Actions">
    Create `.github/workflows/build.yml` to automatically build and push on every commit to `main`:

    ```yaml .github/workflows/build.yml theme={null}
    name: Build and Push

    on:
      push:
        branches: [main]

    env:
      REGISTRY: ghcr.io
      IMAGE_NAME: ${{ github.repository }}

    jobs:
      build-and-push:
        runs-on: ubuntu-latest
        permissions:
          contents: read
          packages: write

        steps:
          - uses: actions/checkout@v4

          - name: Log in to GitHub Container Registry
            uses: docker/login-action@v3
            with:
              registry: ${{ env.REGISTRY }}
              username: ${{ github.actor }}
              password: ${{ secrets.GITHUB_TOKEN }}

          - name: Build and push
            uses: docker/build-push-action@v5
            with:
              context: .
              push: true
              tags: ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ github.sha }}

          - name: Update container image on Magic Containers
            uses: BunnyWay/actions/container-update-image@main
            with:
              app_id: ${{ vars.APP_ID }}
              api_key: ${{ secrets.BUNNYNET_API_KEY }}
              container: app
              image_tag: "${{ github.sha }}"
    ```

    Push your code to trigger the workflow:

    ```bash theme={null}
    git init
    git add .
    git commit -m "Initial commit"
    git remote add origin https://github.com/YOUR_USERNAME/app-astro.git
    git push -u origin main
    ```
  </Tab>

  <Tab title="Docker CLI">
    Build and push manually from your local machine.

    <Steps>
      <Step title="Create a Personal Access Token">
        Go to [GitHub Settings > Developer settings > Personal access tokens](https://github.com/settings/tokens) and create a token with `write:packages` scope.
      </Step>

      <Step title="Log in to GitHub Container Registry">
        ```bash theme={null}
        export CR_PAT=your_personal_access_token
        echo $CR_PAT | docker login ghcr.io -u YOUR_USERNAME --password-stdin
        ```
      </Step>

      <Step title="Build the image">
        ```bash theme={null}
        docker build --platform linux/amd64 -t ghcr.io/YOUR_USERNAME/app-astro:latest .
        ```

        <Info>
          Magic Containers only supports images built for the **linux/amd64** architecture. The `--platform` flag ensures compatibility regardless of your local machine's architecture.
        </Info>
      </Step>

      <Step title="Push to registry">
        ```bash theme={null}
        docker push ghcr.io/YOUR_USERNAME/app-astro:latest
        ```
      </Step>
    </Steps>
  </Tab>
</Tabs>

<Info>
  If your package is private, set the visibility to **Public** in GitHub or
  [configure Magic Containers with registry
  credentials](/magic-containers/image-registries).
</Info>

## Deploy to Magic Containers

<Steps>
  <Step title="Create a new app">
    In the bunny.net dashboard, go to **Magic Containers** and click **Add
    App**. Enter a name and select your deployment option.
  </Step>

  <Step title="Add a container">
    Click **Add Container**, then configure:

    | Field    | Value                                                                        |
    | -------- | ---------------------------------------------------------------------------- |
    | Registry | GitHub Container Registry                                                    |
    | Image    | `YOUR_USERNAME/{imageName}`                                                  |
    | Tag      | `latest` for Docker CLI, or the commit SHA from your GitHub Actions workflow |
  </Step>

  <Step title="Add an endpoint">
    Go to the **Endpoints** tab, click **Add New Endpoint**, and set the
    container port to `80`.
  </Step>

  <Step title="Deploy">
    Click **Add Container**, then **Next Step**, and **Confirm and Create**.
  </Step>
</Steps>

For more details, see the [quickstart guide](/magic-containers/quickstart).

## Test your app

Visit your container URL in the browser to see your Astro site, or test the API route:

```bash theme={null}
curl https://mc-xxx.bunny.run/index.json
```

```json Response theme={null}
{ "message": "Hello from Bunny 🐰" }
```

<Info>
  You can [add a custom hostname](/magic-containers/endpoints) from the **Endpoints** section in your app settings.
</Info>

## Connect a database

You can connect your app to [Bunny Database](/database) directly from the dashboard:

1. Go to **Database > \[Your Database] > Access**
2. Click **Generate Tokens**
3. Click **Add Secrets to Magic Container App**
4. Select your app

The `BUNNY_DATABASE_URL` and `BUNNY_DATABASE_AUTH_TOKEN` environment variables are now available in your app:

```typescript src/pages/api/users.ts theme={null}
import type { APIRoute } from "astro";
import { createClient } from "@libsql/client/web";

const client = createClient({
  url: import.meta.env.BUNNY_DATABASE_URL,
  authToken: import.meta.env.BUNNY_DATABASE_AUTH_TOKEN,
});

export const GET: APIRoute = async () => {
  const result = await client.execute("SELECT * FROM users");

  return new Response(JSON.stringify(result.rows), {
    status: 200,
    headers: {
      "Content-Type": "application/json",
    },
  });
};
```

See the [TypeScript SDK documentation](/database/connect/typescript) for more details.
