This stack configuration has a hook named my-hook, which runs before stack operations. It is a command hook and will store the output from the shell command to hook outputs from where the subsequent hooks and parameter resolvers can access it.

A hook output resolver reads the output of my-hook and sets it as the value of the Greeting parameter.

    resolver: hook-output
