The Dockerfile was designed to build multi-architecture images efficiently.
Golang can build binaries for different architectures using the GOOS and GOARCH environment variables.
In first stage builder we build all binaries for different architectures and in the second stage my-service we copy the binary for the target architecture.
Read comments in the Dockerfile for more details.
