ku: the Kubernetes TUI that just got its MIT license

Tool snapshot

Install

# Fastest: curl installer (auto-detects OS/arch, verifies SHA256, installs to ~/.local/bin)
curl -fsSL https://raw.githubusercontent.com/bjarneo/ku/main/install.sh | sh

# Go install (requires Go 1.26.3+)
go install github.com/bjarneo/ku@latest

# Build from source
git clone https://github.com/bjarneo/ku && cd ku && make install

Real-world workflow

# Launch ku — it validates your kubeconfig before opening (v0.6.3 change)
ku

# Cockpit overview loads immediately: node CPU/MEM, pod counts, recent warnings
# Tab to Workloads → CronJobs in the left sidebar

# Navigate to the problematic CronJob with j/k, hit Enter to expand
# Press L to stream logs from the last triggered Job pod

# If a manual trigger is needed: hit T to trigger the CronJob directly from the TUI
# ku starts read-only — Shift+E to enter edit mode before any mutating action

# Want the raw YAML for auditing?
# Press Y on any resource — raw YAML rendered inline, no separate kubectl get -o yaml

# Check kubectl command preview before running anything destructive
# Press C — ku shows the exact kubectl equivalent of the action you're about to take
