$ go build
Sometimes the compiled binary will dynamically link against multiple shared objects.
$ file go-application
go-application: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically
linked, interpreter /lib64/ld-linux-x86-64.so.2, not stripped
$ ldd go-application
linux-vdso.so.1 => (0x00007ffd36b63000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fbda953c000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fbda9175000)
/lib64/ld-linux-x86-64.so.2 (0x000055801e707000)
To avoid this we’ll have to disable CGO.
$ CGO_ENABLED=0 go build
Now the compiled binary will be statically linked against all dependencies and work in environments where glibc is not available like Alpine Linux.
$ file go-application
go-application: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically
linked, not stripped
$ ldd go-application
not a dynamic executable
