Creating cross-compiled binaries for Go projects is nothing new, and many projects build binaries for more than just linux/amd64, great. Some even build binaries for openbsd/amd64, even better. At the time of writing there’s no Go 1.5 port for OpenBSD yet, however there are some projects which requires Go >= 1.5. E.g. filebeat. So I made a simple Docker image which provides a cross-compiler for any supported Go target, but defaulting to openbsd/amd64: jasperla/go-cross.
