kube-select

A TUI for selecting and connecting to GKE clusters across all your GCP projects, with shell prompt integration so you always know which cluster you're on.

Prerequisites

Tool	Install
gcloud CLI	brew install --cask google-cloud-sdk
kubectl	brew install kubectl
gke-gcloud-auth-plugin	gcloud components install gke-gcloud-auth-plugin
fzf (optional, recommended)	brew install fzf

Make sure you're authenticated:

gcloud auth login

Installation

# Make the script executable
chmod +x kube-select

# Symlink into your PATH (optional)
ln -s "$(pwd)/kube-select" /usr/local/bin/kube-select

Usage

Interactive cluster selection

kube-select

Walks you through:

1. Pick a GCP project from all projects you have access to
2. Pick a GKE cluster within that project (shows location, status, node count)
3. Connects — configures kubectl credentials automatically

Quick-switch between known contexts

kube-select switch

Lists all contexts already in your ~/.kube/config and lets you switch instantly.

Show current cluster

kube-select current

Shell prompt integration

Add to your ~/.zshrc (or ~/.bashrc):

source "/path/to/kube-prompt.sh"

Your prompt will show the active cluster, project, region, and namespace:

☸ my-cluster (my-project/europe-west2)/default ~/code $

The prompt updates automatically whenever you switch contexts.

How it works

• Uses gcloud projects list to enumerate all projects your account can access
• Uses gcloud container clusters list to find GKE clusters in a project
• Uses gcloud container clusters get-credentials to configure kubectl
• If fzf is installed, provides a fuzzy-search TUI; otherwise falls back to a numbered menu
