Is it possible to know which go packages are installed in a binary

Question

I have my go workspace where I develop and then I build a binary and copy it onto a kuberenetes pod and run it. Is it possible to know what go packages are used/installed in the binary?

Answer 1

You can use go version [-m] [file ...]

Go version reports the Go version used to build each of the named executable files.

Output example:

$ go version -m dlv
dlv: go1.14.2
