rancher

rancher is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 42 tokens per session (1,010 once invoked), scanned A, original, MIT.

A management platform for running multiple Kubernetes clusters. Kubernetes is software for deploying and operating container-based applications.

In plain words
What is it for?
Use it to manage EKS, AKS, GKE, on-premises, or edge clusters, inspect Kubernetes resources, and deploy configurations across many clusters.
Why use it?
It gives teams one place to manage clusters running in different clouds or on their own hardware. Shared login and access rules reduce repeated administration across clusters.

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

rancher 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 29d 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.

Rancher

Rancher is a complete software stack for teams adopting containers. It addresses the operational and security challenges of managing multiple Kubernetes clusters.

When to Use

  • Enterprise Multi-Cluster Kubernetes Management: Centralized management of EKS, GKE, AKS, and bare-metal RKE2 clusters.
  • Unified RBAC & Global Authentication: Mapping enterprise Okta/Active Directory groups to Kubernetes RBAC across all clusters.
  • Fleet GitOps Deployment: Continuous delivery of Kubernetes configurations across thousands of geographically distributed clusters.
  • Cluster Security & CIS Benchmarks: Running scheduled automated security audits and compliance scans.

Quick Start

# Run Rancher server locally with Docker
docker run -d --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  --privileged \
  rancher/rancher:latest

# Access Rancher management console at https://localhost

Core Concepts

Fleet GitOps Multi-Cluster Deployment (fleet.yaml)

Distributing workloads to targeted clusters based on labels:

# fleet.yaml in Git repository root
defaultNamespace: production

labels:
  app: payment-gateway

# Target clusters matching specific environment labels
targetCustomizations:
  - name: production-clusters
    clusterSelector:
      matchLabels:
        env: production
        region: us-east
    helm:
      values:
        replicaCount: 5
        ingress:
          enabled: true
          host: payment.us-east.example.com

  - name: staging-clusters
    clusterSelector:
      matchLabels:
        env: staging
    helm:
      values:
        replicaCount: 2
        ingress:
          enabled: true
          host: payment.staging.example.com

RKE2 Secure Cluster Node Provisioning

Configuring hardened Kubernetes control-plane node:

# /etc/rancher/rke2/config.yaml
write-kubeconfig-mode: "0600"
tls-san:
  - "k8s-api.company.internal"
  - "10.0.1.10"
cni: "cilium" # Modern eBPF network plugin
profile: "cis-1.23" # Enforce CIS benchmark profile

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.

rancher is a skill published in the GitHub repository G1Joshi/Agent-Skills (15 stars, last pushed 29d ago), licensed MIT. It adds 42 tokens to every session and 1,010 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
