And on a similar naming note yet totally unrelated, check out k9s, which is a TUI for Kubernetes cluster admin. All kinds of nifty features built-in, and highly customizable.
If we're talking about CLIs, check out Kamal, the build system that 37signals / Basecamp / DHH developed, specifically to move off the cloud. I think it uses Kubernetes but not positive, it might just be Docker.
