Setup Docker Buildx For Multi Arch builds

By default buildx plugin is availabe on Docker Desktop, and if Docker was installing using deb packages. In case it is not installed, we can get it from Docker buildx - GitHub and put it to ~/.docker/cli-plugins directory, and make it executable using the following command -

$ chmod +x ~/.docker/cli-plugins/docker-buildx

To be able to build Multi-Arch Docker Images -

$ docker run --privileged --rm tonistiigi/binfmt --install all
$ docker buildx create --name multibuilder
$ docker buildx use multibuilder
$ docker buildx inspect --bootstrap

And that's it! Now we can run docker buildx on our Dockerfile(s) to build them for Multi Architecture.
