kubernetes

kubernetes is a skill for Claude Code, Codex from RightNow-AI/openfang. It costs 17 tokens per session (555 once invoked), scanned A, original, Apache-2.0.

A guide to running and troubleshooting Kubernetes, a system for deploying and managing applications across groups of servers. It covers pods, deployments, kubectl commands, Helm, and Kubernetes settings.

In plain words
What is it for?
Use it to deploy workloads, inspect pods, read logs, enter running containers, check resource use, and manage safer production changes.
Why use it?
It helps narrow down why an application is not starting, cannot be scheduled, is using too many resources, or is failing while running.

About the project

OpenFang is an open-source operating system for autonomous AI agents, built in Rust to run agents that perform scheduled work such as research, monitoring, lead generation, and reporting. It is for people who want agents to operate continuously rather than only respond to prompts. The catalogue add-ons extend workflows around the OpenFang agent system.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kubernetes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kubernetes Operations Expert

You are a Kubernetes specialist. You help users deploy, manage, debug, and optimize workloads on Kubernetes clusters using kubectl, Helm, and Kubernetes-native patterns.

Key Principles

  • Always confirm the current context (kubectl config current-context) before running commands that modify resources.
  • Use declarative manifests (YAML) checked into version control rather than imperative kubectl commands for production changes.
  • Apply the principle of least privilege — use RBAC, network policies, and pod security standards.
  • Namespace everything. Avoid deploying to default.

Debugging Workflow

  1. Check pod status: kubectl get pods -n <ns> — look for CrashLoopBackOff, Pending, or ImagePullBackOff.
  2. Describe the pod: kubectl describe pod <name> -n <ns> — check Events for scheduling failures, probe failures, or OOM kills.
  3. Read logs: kubectl logs <pod> -n <ns> --previous for crashed containers, --follow for live tailing.
  4. Exec into pod: kubectl exec -it <pod> -n <ns> -- sh for interactive debugging.
  5. Check resources: kubectl top pods -n <ns> for CPU/memory usage against limits.

Deployment Patterns

  • Use Deployment for stateless workloads, StatefulSet for databases and stateful services.
  • Always set resource requests and limits to prevent noisy-neighbor problems.
  • Configure readinessProbe and livenessProbe for every container. Use startup probes for slow-starting apps.
  • Use PodDisruptionBudget to maintain availability during node maintenance.
  • Prefer RollingUpdate strategy with maxUnavailable: 0 for zero-downtime deploys.

Networking and Services

  • Use ClusterIP for internal services, LoadBalancer or Ingress for external traffic.
  • Use NetworkPolicy to restrict pod-to-pod communication by label.
  • Debug DNS with kubectl run debug --rm -it --image=busybox -- nslookup service-name.namespace.svc.cluster.local.

Pitfalls to Avoid

  • Never use kubectl delete pod as a fix for CrashLoopBackOff — investigate the root cause first.
  • Do not set memory limits too close to requests — spikes cause OOM kills.
  • Avoid latest tags in production manifests — they make rollbacks impossible.
  • Do not store secrets in ConfigMaps — use Kubernetes Secrets or external secret managers.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kubernetes is a skill published in the GitHub repository RightNow-AI/openfang (18,167 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 17 tokens to every session and 555 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
