## What it is
An official GitHub Action that sets up Docker Buildx in CI workflows, creating and booting a builder using the docker-container driver. It enables multi-platform image builds and BuildKit cache export in GitHub Actions pipelines.

## Use cases
- set up docker buildx in github actions
- build multi-platform docker images in ci
- enable buildkit cache export in workflows
- configure a docker builder for github actions ci
- pin buildkit version in ci pipeline
- build arm64 images from x86 github runners

## When to choose
- You build Docker images in GitHub Actions and need Buildx/BuildKit features
- You need multi-platform image builds or cache export in CI
- You use docker/build-push-action and need a builder set up first

## When to avoid
- You build images outside GitHub Actions (use Docker CLI directly)
- You only need plain legacy docker build without Buildx
- You use a different CI system than GitHub Actions
