Always a hot-topic in Go circles is binary size of applications. In this post we will show you how you can reduce the binary size produced from go build for leaner, slimer builds.

In short, adding the ldflags shown below will reduce the size of the binary produced. It does this by removing some perhaps non-critial parts (shouldn’t affect execution, only debugging potentially).

-s Will turn off the symbol table, so you won’t be able to use commands like go tool nm.
