Source: Create a Serverless Application in Golang With Aws
env GOOS=linux go build -ldflags="-s -w" -o bin/hello hello/main.go
env GOOS=linux go build -ldflags="-s -w" -o bin/world world/main.go
You will get the smallest binaries if you compile with -ldflags '-w -s'.
The -w turns off DWARF debugging information: you will not be able to use gdb on the binary to look at specific functions or set breakpoints or get stack traces, because > all the metadata gdb needs will not be included. You will also not be able to use other tools that depend on the information, like pprof profiling.
The -s turns off generation of the Go symbol table: you will not be able to use go tool nm to list the symbols in the binary. strip -s is like passing -s to -ldflags but it > doesn't strip quite as much. go tool nm might still work after strip -s. I am not completely sure.
None of these — not -ldflags -w, not -ldflags -s, not strip -s — should affect the execution of the actual program. They only affect whether you can debug or analyze the > program with other tools.
