### BitBucket Pipelines 

```yaml
# Prerequisites: $DOCKER_USER, $DOCKER_PAT setup as deployment variables
# This pipeline assumes $BITBUCKET_REPO_SLUG as the image name
# Replace <ORG> in the `docker buildx create` command with your Docker org

image: atlassian/default-image:3

pipelines:
  default:
    - step:
        name: Build multi-platform image
        script:
          - mkdir -vp ~/.docker/cli-plugins/
          - 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\"))")
          - curl --silent -L --output ~/.docker/cli-plugins/docker-buildx $BUILDX_URL
          - chmod a+x ~/.docker/cli-plugins/docker-buildx
          - echo "$DOCKER_PAT" | docker login --username $DOCKER_USER --password-stdin
          - docker buildx create --use --driver cloud "<ORG>/default"
          - IMAGE_NAME=$BITBUCKET_REPO_SLUG
          - docker buildx build
            --platform linux/amd64,linux/arm64
            --push
            --tag "$IMAGE_NAME" .
        services:
          - docker
```

### 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
Title: Bitbucket Pipelines and Shell Script Examples for Docker Build Cloud
Summary
This section provides examples of how to use Docker Build Cloud in Bitbucket Pipelines and a generic shell script. The Bitbucket Pipelines example demonstrates how to set up the environment, download and configure buildx, login to Docker, create a buildx driver, and build and push a multi-platform image. The shell script example outlines the steps to download the buildx binary, set permissions, login to Docker Hub using a Personal Access Token, and use buildx.
