+# Build Multi-Architecture Docker Images with Buildx
+
+Please refer to [Docker Docs](https://docs.docker.com/buildx/working-with-buildx) to enable Buildx.
+
+Run `make images` to start build the images.
+
+Run `make push` to push the images into registry.
+Registry repo can be configured with environment variable:
+
+```bash
+DOCKER_REGISTRY=<your registry> make push
+```
+
+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:
+
+```bash
+$ 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](https://docs.docker.com/buildx/working-with-buildx/#work-with-builder-instances).
