About:
Kube-ps1 is a lightweight shell script that injects current Kubernetes context and namespace information directly into your prompt. It supports both bash and zsh, providing immediate visibility into your active cluster configuration. This prevents accidental operations on the wrong environment and streamlines the workflow for developers managing multiple clusters.

Key Features:

Displays current Kubernetes context and namespace in the prompt
Supports both bash and zsh shells
Shows indicator when using a service account
Lightweight with no external dependencies beyond kubectl
Highly customizable prompt symbols and colors

Use Cases:

DevOps engineers switching between production and development clusters
Developers working with multiple Kubernetes namespaces simultaneously
System administrators managing distinct clusters for different projects

Alternatives:

starship – A more comprehensive, cross-shell prompt that includes Kubernetes support as one of many features, whereas kube-ps1 is dedicated solely to K8s.
kubectx – A tool for switching contexts/namespaces, while kube-ps1 focuses on visualizing the current state in the prompt rather than changing it.
