go-grpc-health

Simple binary, which checks if grpc server is started or not

Build

As any GO package.

If you're not familiar with go or don't have golang installed in a system, then run:

$ ./build.sh

This script should produce static binary go-grpc-health for your host OS.

Crosscompilation

You also can produce binary from any os for any other OS, thanks to GO:
