Heck, you can even cross compile go code for any architecture to another one (even for different OSes), and docker would be useless there unless docker has mechanisms to bind qemu-$ARCH with containers and binfmt.
Are you running on bare servers? Sure, a Go binary and a script is fine.
I understand what the OP is saying but not sure they get this context.
If I were working in that world still I might have that single binary, and a script, but I'm old school and would probably make an RPM package and add a systemd unit file and some log rotate configs too!
