# Build Multi-Architecture Docker Images with Buildx

Please refer to https://docs.docker.com/buildx/working-with-buildx/ to enable Buildx.

Run `make builder` to create Buildx instance before starting to build the images.

Run `make images` to start build the images.

Thanks for adding this section. Can we provide more context around why and when a user will need to run make builder? How about something like:

In some local environments like Ubuntu, where the default Buildx builder uses the docker driver, the make images command might fail with the following error:

$ make images
multiple platforms feature is currently not supported for docker driver. Please switch to a different driver (eg. "docker buildx create --use")
Makefile:57: recipe for target 'images' failed
make: *** [images] Error 1

To fix this, you can create a new Buildx builder instance by running make builder. This command will create a builder that uses the docker-container driver that can build multi-platform images. For more information, see the Buildx builder documentation.
