Makefile allows you to build code on different platforms.

To make push you need to authorize google:

#install Google Cloud Code extantions to vscode
$ gcloud auth login
$ gcloud config set project minikube-385711
$ gcloud auth configure-docker

With this Makefile, you can specify the TARGETOS, TARGETOSARCH and REGESTRY variables when running the make command.

For example, to build the code for Linux on an AMD64/ARM64 architecture, and push to Google container registry, you would run:

$ make linux TARGETOSARCH=amd64 REGESTRY=HOSTNAME/PROJECT-ID
$ make linux TARGETOSARCH=arm64 REGESTRY=HOSTNAME/PROJECT-ID

For example, to build the code for MacOS on an ARM64/ARM64 architecture, and push to Docker Hub container registry, you would run:

$ make macos TARGETOSARCH=amd64 REGESTRY=yourhubusername
$ make macos TARGETOSARCH=arm64 REGESTRY=yourhubusername

For example, to build the code for Windows on an AMD64/ARM64 architecture, you would run:

$ make windows TARGETOSARCH=amd64
$ make windows TARGETOSARCH=arm64

The full list is based on the result of the command go tool dist list. The "32-bit/64-bit" information is based on https://golang.org/doc/install/source.
