I forgot to mention! Sometime last year I wrote kubeplay. It is intended for interactive scripting, like a REPL basically.
Personally, I find kubectl to tedious, and gluing it with shell scripts can be even more tedious.
Currently, kubeplay uses Ruby syntax (via mruby embedded in a Go program), but I am keen to explore other options. I am also not a fan of pseaudo-graphical interactive console apps, so this more of a pure REPL based on a proper language 
Take a look and let me know if you would be keen to use it, I would love to put more time into it!
