k3s-public-ops

k3s-public-ops is a skill for Claude Code, Codex from Agent-Hellboy/mcp-runtime. It costs 89 tokens per session (1,510 once invoked), scanned A, original, Apache-2.0.

A runbook for operating and debugging a public k3s cluster, a lightweight Kubernetes cluster, used by MCP Runtime.

In plain words
What is it for?
Use it to set up, clean, restore, or roll out the public deployment and to validate changes on the live cluster.
Why use it?
It keeps deployment and recovery work consistent and helps diagnose registry, DNS, image-download, and TLS certificate problems.

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

k3s-public-ops scanned grade A with 1 finding 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

k3s Public Ops

Use this skill for the mcpruntime.org style public k3s deployment. Prefer the documented user-facing commands and scripts over private shortcuts.

Source Of Truth

  • Env profile: config/deployments/mcpruntime-org.env
  • Example profile: config/deployments/mcpruntime-org.env.example
  • Runbook: docs/k3s-deployment-runbook.md
  • Readiness/debug guide: docs/cluster-readiness.md
  • Scripts (canonical): hack/deploy/mcpruntime-org/{setup,clean,restore,rollout,multitenancy-test}.sh
  • Script index: hack/README.md

Non-Negotiables

  • Rebuild ./bin/mcp-runtime before setup or rollout validation. Stale CLI binaries can stamp stale registry image refs.
  • cluster doctor uses KUBECONFIG env, not --kubeconfig:
KUBECONFIG=/private/tmp/mcpruntime-k3s.yaml ./bin/mcp-runtime cluster doctor
  • For public bundled HTTPS, platform and tenant pull refs should use the TLS-covered hostname, for example registry.mcpruntime.org/....
  • Do not use a registry Service ClusterIP as a bundled-HTTPS pull ref unless the cert has the matching IP SAN. The usual symptom is: x509: cannot validate certificate for <ClusterIP> because it doesn't contain any IP SANs.
  • Pod DNS and node image-pull DNS are different. Pods can resolve registry.registry.svc.cluster.local; k3s/containerd on the node usually cannot unless /etc/rancher/k3s/registries.yaml explicitly mirrors that exact host.
  • Public registry ingress is auth-protected. Platform workloads using registry.<domain> need an image pull secret; setup should create and attach mcp-runtime-registry-pull for platform namespaces before registry auth is re-enabled. Unauthenticated pulls may fail with no basic auth credentials.

Public k3s Setup Validation

Run the actual script path:

bash -n hack/deploy/mcpruntime-org/setup.sh
bash hack/deploy/mcpruntime-org/setup.sh
KUBECONFIG=/private/tmp/mcpruntime-k3s.yaml ./bin/mcp-runtime cluster doctor
kubectl --kubeconfig /private/tmp/mcpruntime-k3s.yaml get pods -A

What this file has done since we first saw it

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.

k3s-public-ops is a skill published in the GitHub repository Agent-Hellboy/mcp-runtime (6 stars, last pushed 2d ago), licensed Apache-2.0. It adds 89 tokens to every session and 1,510 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
