Enable BuildKit

Before we start building images, ensure you have enabled BuildKit on your machine. BuildKit allows you to build Docker images efficiently. For more information, see Building images with BuildKit.

BuildKit is enabled by default for all users on Docker Desktop. If you have installed Docker Desktop, you don't have to manually enable BuildKit. If you are running Docker on Linux, you can enable BuildKit either by using an environment variable or by making BuildKit the default setting.

To set the BuildKit environment variable when running the docker build command, run:

$ DOCKER_BUILDKIT=1 docker build .

To enable docker BuildKit by default, set daemon configuration in /etc/docker/daemon.json feature to true and restart the daemon. If the daemon.json file doesn't exist, create new file called daemon.json and then add the following to the file.

{
  "features":{"buildkit" : true}
}

Restart the Docker daemon.
