Hi,
I am looking to compile images for arm64 using docker buildx as I could see on some posts. I tried docker stable 19.03 version as well as beta versions, none of them seem to have ‘docker buildx’ . Appreciate any pointers.
$ docker version
Client:
Version: 19.03.0-beta3
API version: 1.40
Go version: go1.12.4
Git commit: c55e026
Built: Thu Apr 25 02:58:59 2019
OS/Arch: linux/amd64
Experimental: true

Thanks,

I had also to enable experimental features for the CLI with:

export DOCKER_CLI_EXPERIMENTAL=enabled
docker buildx version
github.com/docker/buildx v0.3.1-tp-docker 6db68d029599c6710a32aa7adcba8e5a344795a7
