  Primary source of truth for the Docker "Official Images" program

  

CAUTION! To build container images with multi-CPU architecture support, you need to use parent image which supports multiple CPU architectures. Most of the official images on Docker Hub provide a variety of architectures. For example, the openjdk image variants (which we're going to use later) support arm64v8 and amd64.

  Docker CLI plugin for extended build capabilities with BuildKit

  

To make it possible to build multi-CPU architecture container images we need to install Docker Buildx. Docker Buildx is a CLI plugin that extends the docker command with some additional features, and multi-arch builds is one of those. If you're using recent Docker Desktop or Docker for Linux packages chances are high that Buildx is already available for you. If not, check the installation instructions.
