Hi,
I've just started to use the handy `new awsx.ecs.FargateService`

therefore I am building docker images via pulumi, I am on an M1 mac, which means that if I try to build and push to ECR/ECS an image it will be in the wrong architecture to run in ECS later on.

Do you know if there's a way to force buildx to build for a certain architecture? Or a way to pass the flag to pulumi?

Thanks

This will enable buildkit, but to have it use `buildx` instead of `build`, you might be best taking docker’s advice of aliasing `buildx` to `build`
```        image: awsx.ecs.Image.fromDockerBuild(`${appName}-image`, {
          env: {
            DOCKER_BUILDKIT: "1",
          },
        }),```

thanks yes I did alias docker build to docker buildx but I also want to make sure that when I build an image with pulumi I do a buildx for the right platform (not M1)

but I guess I can pass a param in the env there

actually no I can't because it's a param..
such as
```--platform linux/amd64,linux/arm64,linux/ppc64le ```
