kubernetes-patterns

kubernetes-patterns is a skill for Claude Code, Codex from j4flmao/agent-skills. It costs 0 tokens per session (432 once invoked), scanned A, original, MIT.

A guide to advanced Kubernetes design patterns, including sidecars, traffic proxies, custom controllers, admission webhooks, and scheduling rules. It also covers ways to keep workloads available during disruptions.

In plain words
What is it for?
Use it to design sidecar and ambassador containers, Operators, admission webhooks, disruption budgets, taints, tolerations, and affinity rules.
Why use it?
It helps solve deployment problems involving resilience, workload placement, cluster changes, and communication between containers.

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-patterns 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.

What it actually says

Advanced Kubernetes Patterns

1. Skill Context

Focus: Sidecar, Ambassador, Operator patterns, Admission Webhooks, Node affinity, and workload resiliency. Triggers: k8s patterns, kubernetes operator, mutating webhook, pod disruption budget, advanced scheduling

2. Advanced Kubernetes Architecture

The agent must design resilient, self-healing, and highly available Kubernetes deployments.

Structural Patterns

  • Sidecar Pattern: Augmenting the main container (e.g., logging agent, OTel collector, proxy).
  • Ambassador Pattern: A sidecar that proxies network connections to the outside world, handling retries, circuit breaking, and mTLS (e.g., Envoy).
  • Operator Pattern: Extending the K8s API using Custom Resource Definitions (CRDs) and writing custom controllers (in Go/Rust) to manage complex stateful applications (e.g., running PostgreSQL clusters).

Resiliency & Scheduling

  • Pod Disruption Budgets (PDBs): Preventing cluster administrators or autoscalers from draining nodes if it would drop a deployment below a minimum available threshold (quorum).
  • Taints, Tolerations, and Affinity:
    • Taints: Repelling pods from specific nodes (e.g., GPU nodes or dedicated tenant nodes).
    • Affinity: Attracting pods to specific nodes or ensuring pods from the same deployment do not land on the same physical underlying host (podAntiAffinity with topologyKey: kubernetes.io/hostname).

Security & Governance

  • Admission Webhooks: Using ValidatingAdmissionWebhook to reject deployments that violate policy (e.g., running as root) or MutatingAdmissionWebhook to automatically inject sidecars or environment variables.

3. Output Format

  • Provide deeply commented Kubernetes YAML manifests.
  • Diagram the communication flow between custom controllers and the API server.
  • Focus on zero-downtime deployments and graceful shutdown (e.g., preStop hooks and terminationGracePeriodSeconds).
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

kubernetes-patterns is a skill published in the GitHub repository j4flmao/agent-skills (23 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 432 tokens. 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.
