kube-noob

No AI inside. Works with yours. kube-noob is a Kubernetes, OpenShift, ROSA HCP, Helm and RHACS/StackRox expert in a box: audit rules, read-only-first playbooks, cited docs and graded exercises. Claude, OpenShift Lightspeed or any MCP client calls it as tools; the CLI runs it with no AI at all. It makes no network calls unless you turn them on.

• Audit: 60 rules plus strict schemas (Kubernetes 1.35, Routes, SCCs, EgressFirewall, Gateway API, StackRox), removed-API checks, safe auto-fixes, 9 red-team scenarios, RHACS policy mapping.
• Generate: hardened manifests and Helm charts, re-audited before return.
• Debug: 38 offline playbooks, read-only steps first; reported OpenShift bugs with their fix version; policy denials explained (Kyverno, Gatekeeper, Pod Security, SCC, RBAC); NetworkPolicy reachability; read-only cluster evidence (never Secrets).
• Learn: 5 tracks, 16 lessons, graded exercises; remembers confirmed fixes locally.
• Cite: answers cite local knowledge as [kn:<doc>#<n>].

Every design request runs a 7-step protocol: Clarify, Validate, Research, Audit, Calibrate, Generate, Red Team.

Who does the thinking

Quick start

brew tap aashishmahajan/kube-noob https://github.com/aashishmahajan/kube-noob
brew trust --formula aashishmahajan/kube-noob/kube-noob
brew install kube-noob
kube-noob demo --list
kube-noob audit -f k8s/ --platform openshift --version 4.22
kube-noob diagnose 'paste events or errors'
kube-noob doctor
kube-noob selftest

Short form: noob. No Homebrew: uv tool install kube-noob or pipx install kube-noob (Python 3.11+, not macOS's built-in 3.9). Errors: install. Roles, demos: use cases.

Use with Claude or any MCP client

Claude plugin, in Claude Code (needs uv):

/plugin marketplace add aashishmahajan/kube-noob
/plugin install kube-noob@kube-noob

In claude.ai or the desktop app: Customize > Plugins > Add > Add marketplace, aashishmahajan/kube-noob.

Any MCP client:

{"mcpServers": {"kube-noob": {"command": "uvx", "args": ["--from", "kube-noob==0.4.0", "kube-noob", "mcp"]}}}

Cluster and web tools appear when enabled.

Run on OpenShift

As a token-protected service, a loopback-only sidecar, or a tool for OpenShift Lightspeed: docs/openshift.md. The chart ships NetworkPolicies and runs under restricted-v2.

Safe by default

kube-noob doctor shows what it can reach. Config never comes from the current directory implicitly. All keys: kube-noob.example.yaml.
