### Shell script

```bash
#!/bin/bash

# Get download link for latest buildx binary. Set $ARCH to the CPU architecture (e.g. amd64, arm64)
ARCH=amd64
BUILDX_URL=$(curl -s https://raw.githubusercontent.com/docker/actions-toolkit/main/.github/buildx-lab-releases.json | jq -r ".latest.assets[] | select(endswith(\"linux-$ARCH\"))")

# Download docker buildx with Build Cloud support
mkdir -vp ~/.docker/cli-plugins/
curl --silent -L --output ~/.docker/cli-plugins/docker-buildx $BUILDX_URL
chmod a+x ~/.docker/cli-plugins/docker-buildx

# Login to Docker Hub. For security reasons $DOCKER_PAT should be a Personal Access Token. See https://docs.docker.com/build-cloud/ci/#creating-access-tokens
echo "$DOCKER_PAT" | docker login --username $DOCKER_USER --password-stdin

# Connect to your builder and set it as the default builder
docker buildx create --use --driver cloud "<ORG>/default"

# Cache-only image build
docker buildx build \
    --tag temp \
    --output type=cacheonly \
    .

# Build, tag, and push a multi-arch docker image
docker buildx build \
    --platform linux/amd64,linux/arm64 \
    --push \
    --tag "<IMAGE>" \
    .
```

### Docker Compose

Use this implementation if you want to use `docker compose build` with
Docker Build Cloud in CI.

```bash
#!/bin/bash

# Get download link for latest buildx binary. Set $ARCH to the CPU architecture (e.g. amd64, arm64)
ARCH=amd64
BUILDX_URL=$(curl -s https://raw.githubusercontent.com/docker/actions-toolkit/main/.github/buildx-lab-releases.json | jq -r ".latest.assets[] | select(endswith(\"linux-$ARCH\"))")
COMPOSE_URL=$(curl -sL \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer <GITHUB_TOKEN>" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/repos/docker/compose-desktop/releases \
  | jq "[ .[] | select(.prerelease==false and .draft==false) ] | .[0].assets.[] | select(.name | endswith(\"linux-${ARCH}\")) | .browser_download_url")

# Download docker buildx with Build Cloud support
mkdir -vp ~/.docker/cli-plugins/
curl --silent -L --output ~/.docker/cli-plugins/docker-buildx $BUILDX_URL
curl --silent -L --output ~/.docker/cli-plugins/docker-compose $COMPOSE_URL
chmod a+x ~/.docker/cli-plugins/docker-buildx
chmod a+x ~/.docker/cli-plugins/docker-compose

# Login to Docker Hub. For security reasons $DOCKER_PAT should be a Personal Access Token. See https://docs.docker.com/build-cloud/ci/#creating-access-tokens
echo "$DOCKER_PAT" | docker login --username $DOCKER_USER --password-stdin

# Connect to your builder and set it as the default builder
docker buildx create --use --driver cloud "<ORG>/default"

# Build the image build
docker compose build
```
Title: Shell Script and Docker Compose Examples for Docker Build Cloud
Summary
This section provides shell script and Docker Compose examples for using Docker Build Cloud. The shell script demonstrates how to download and configure buildx, log in to Docker Hub using a Personal Access Token, create and use a buildx driver connected to Build Cloud, build a cache-only image, and build, tag, and push a multi-arch Docker image. The Docker Compose example shows how to download and configure both buildx and Docker Compose, log in to Docker Hub, connect to a Build Cloud builder, and then use `docker compose build`.
