Now let's create a container builder named `gpubuilder` using Buildx:
```console
$ docker buildx create --name gpubuilder --driver-opt "image=crazymax/buildkit:v0.23.2-ubuntu-nvidia" --bootstrap
$ docker buildx create --name gpubuilder --driver-opt "image=moby/buildkit:buildx-stable-1-gpu" --bootstrap
