## What it is
Docker Buildx is a Docker CLI plugin that provides extended image build capabilities powered by BuildKit. It supports multiple builder instances, multi-platform image builds, and high-level build orchestration via Bake.

## Use cases
- build docker images with buildkit
- build multi-architecture container images
- create and manage docker builder instances
- build images for arm64 on an x86 machine
- run complex multi-image builds with bake
- build docker images inside kubernetes

## When to choose
- you need BuildKit features not available in the legacy docker build
- you need to build multi-platform or multi-architecture images
- you want to manage multiple isolated builders or remote builders
- you want declarative, high-level build workflows with Bake

## When to avoid
- you only need simple, single-platform image builds with the default docker build
- you are not using Docker or a BuildKit-compatible engine
- you need to build non-container artifacts
