# KETIKA CGO_ENABLED = 0 DIHAPUS, EXECUTEABLE TIDAK DITEMUKAN DI DIRECTORY
# CGO_ENABLED = 0 untuk membuat hasil binerny tidak akan terhubung ke library C apapun
# With CGO_ENABLED=0 you got a staticaly-linked binary 
#(see: https://en.wikipedia.org/wiki/Static_build) 
# so it will run without any external dependencies 
# (you can buld your dockers from 'scratch' image)
