If this name is not uwusome enough for you, Kubernetes v1.30 brings 45 enhancements, including 10 alpha features and 17 graduating to stable. Read more by following the links below, and enjoy trying them out in your clusters!

Ever thought of bringing some COLOUR to the kubectl output in your terminal? This small tool with a self-explanatory name has you covered.

🌈 kubecolor works as a wrapper for your kubectl command, adding colours to its output. That should be enough to give it a try! Anyway, here are some other brief facts on kubecolor:
- You can customise the colours used in the tool.
- You can use kubecolor as a complete alternative to kubectl — e.g., add alias kubectl="kubecolor" to your .bash_profile.
- It works for both kubectl and oc (OpenShift CLI).
- Autocompletion is available. There are instructions for Bash, zsh, fish, and PowerShell.
- Not all kubectl subcommands are supported, and the kubectl plugins’ output is not colorised at the moment.
- It is written in Go and installable as a binary or using Homebrew, Scoop, Nix, AUR, and Termux (Android).

P. S. Originally, the project was launched and available at hidetatz/kubecolor. However, this repo was archived a year ago. Now, it goes on as kubecolor/kubecolor, which is “a heavily modified version of the original KubeColor”.

There are many ways to make your CLI more convenient and powerful, and jnv is one of them if you often work with JSONs. Kubernetes is not just about YAMLs, right?

In essence, jnv is an interactive JSON viewer with an embedded jq filter editor. It helps you navigate your JSON objects easily. You can use it instead of kubectl … | jq -r … to benefit from a more interactive experience.

Here are its main features:

- Getting input from JSON files or stdin (think of kubectl … -o json).
- Applying your jq filters (with auto-completion) to the current object on the fly.
- Numerous key bindings to move around the object, expand the folds, etc.
- Written in Rust. Installation via Homebrew, MacPorts, Nix, or Cargo (Rust's package manager).

Now, you are ready to change your role from a YAML developer to a JSON one, aren't you? 🤣
