Prepearing docker for buildx (multiplatform build)

Switch docker to latest age version. You need to switch deamon and client.

http://collabnix.com/building-arm-based-docker-images-on-docker-desktop-made-possible-using-buildx/

Then enable Experimental features.

You can check result by issuing:

docker version

I have next output:

 docker-init:

  GitCommit:        fec3683

Mention Age version 19.03.xx and Experimental - True.

Then build buildx

docker build --platform=local -o . git://github.com/docker/buildx

And copy it to - profile dir .docker

.docker\cli-plugins\docker-buildx.exe

Then your buildx should work:

docker buildx ls

Then you can build multiplatform image with command like:

docker buildx build --platform linux/amd64,linux/arm64 -t registry.gitlab.com/gintsgints/vue-fullstack/client:latest --push .
