Tools

Kui is described as a hybrid CLI/UI development experience for cloud-native applications. It provides similar functionality to parts of kubectl, but combines a terminal with rich GUI output as well. Interesting tool and a novel user interface.

Homebrew is a popular package manager for macOS. Homebrew Bundle provides a way of describing in a single file all the desired packages, and then installing them in one command. Handy for sharing dependencies between machines.
