issue with pflag flagset
Cobra has lots of features, but is really complex and intrusive, especially for a newcomer. I would advise you to have a look at clap (https://github.com/fred1268/go-clap) which is very easy to use and absolutely non intrusive. All you need to do is to create a struct containing the fields you want to retrieve from the command line, and annotate it with standard Go tags.

convert interface{} to []interface{}
For some in depth examples on how to use reflection in Go and transform types into others, I would suggest you to have a look at clap, the Command Line Argument Parser, and more specifically this file.

Show HN: New set of Go libraries for CLI Development
Hello everyone,
I've just released three different libraries aimed at either enhancing or facilitating CLI application development.
Flags (https://github.com/reeflective/flags)
-
Libraries for CLI and console applications
Flags (https://github.com/reeflective/flags) flags aims to merge the concepts from https://github.com/jessevdk/go-flags, and https://github.com/octago/sflags, both relying on struct tags to define CLI command specs. The flags library uses these underlying concepts to produce complete `cobra.Command` trees, and brings many comfort-of-life improvements for the generated applications/commands.
What are some alternatives?
console - Closed-loop application library for Cobra commands (powerful, ready-to-run and easy to use)
cobra - A Commander for modern Go CLI interactions
go-flags - go command line option parser
pflag - Drop-in replacement for Go's flag package, implementing POSIX/GNU-style --flags.
readline - Shell library with powerful and modern UI, large feature set, and `.inputrc` support
exitplan - Golang Exit Callback for SIGINT & SIGTERM
cobrass - 🐲 Assistant for cli applications using cobra
sflags - Generate flags by parsing structures
urfave/cli - A simple, fast, and fun package for building command line apps in Go
go-arg - Struct-based argument parsing in Go
