  Before you can start using Docker Build Cloud, you must add the builder to your local
  environment.
  Prerequisites
  To get started with Docker Build Cloud, you need to:
  Download and install Docker Desktop version 4.26.0 or later.
  Create a cloud builder on the
  Docker Build Cloud Dashboard
  When you create the builder, choose a name for it (for example,
  default
  ). You will use this name as
  BUILDER_NAME
  in the CLI steps below.
  Use Docker Build Cloud without Docker Desktop
  To use Docker Build Cloud without Docker Desktop, you must download and install
  a version of Buildx with support for Docker Build Cloud (the
  cloud
  driver).
  You can find compatible Buildx binaries on the releases page of
  this repository
  If you plan on building with Docker Build Cloud using the
  docker compose build
  command, you also need a version of Docker Compose that supports Docker
  Build Cloud. You can find compatible Docker Compose binaries on the releases
  page of
  this repository
  Steps
  You can add a cloud builder using the CLI, with the
  docker buildx create
  command, or using the Docker Desktop settings GUI.
  Docker Desktop
  Sign in to your Docker account.
  docker login
  Add the cloud builder endpoint.
  docker buildx create --driver cloud <ORG>/<BUILDER_NAME>
  Replace
  <ORG>
  with the Docker Hub namespace of your Docker organization (or your username if you are using a personal account), and
  <BUILDER_NAME>
  with the name you chose when creating the builder in the dashboard.
  This creates a local instance of the cloud builder named
  cloud-ORG-BUILDER_NAME
  Note
  If your organization is
  acme
  and you named your builder
  default
  , use:
  docker buildx create --driver cloud acme/default
  Sign in to your Docker account using the
  Sign in
  button in Docker Desktop.
  Open the Docker Desktop settings and navigate to the
  Builders
  tab.
  Under
  Available builders
  , select
  Connect to builder
  The builder has native support for the
  linux/amd64
  linux/arm64
  architectures. This gives you a high-performance build cluster for building
  multi-platform images natively.
  Firewall configuration
  To use Docker Build Cloud behind a firewall, ensure that your firewall allows
  traffic to the following addresses:
  https://auth.docker.io
  https://build-cloud.docker.com
  https://hub.docker.com
