Enable Docker BuildKit for Go by setting DOCKER_BUILDKIT=1 before running docker build to get faster, more efficient builds.
Enable Docker BuildKit for Go builds by setting the DOCKER_BUILDKIT=1 environment variable before running docker build. This activates the newer build engine which supports features like multi-stage builds and better caching.
export DOCKER_BUILDKIT=1
docker build -t my-go-app .
Alternatively, enable it permanently by adding buildx to your Docker daemon configuration or using docker buildx build directly.
Docker BuildKit is a faster, smarter way to build container images. It helps your Go applications compile quicker and use less disk space by remembering which parts of your code haven't changed. Think of it like a chef who only cooks the ingredients that actually changed, rather than starting the whole meal from scratch every time.
