Triage Kubernetes Node Pressure

Triage Kubernetes Node Pressure is a skill for Claude Code, Codex from bregman-arie/devops-sre-skills. It costs 22 tokens per session (506 once invoked), scanned A, original, Apache-2.0.

A troubleshooting guide for Kubernetes nodes affected by memory, disk, or process pressure. A node is a computer in a Kubernetes cluster that runs pods.

In plain words
What is it for?
Use it to inspect node conditions, identify the largest contributors, choose actions such as cleanup or workload movement, and verify that pressure and evictions stop.
Why use it?
It helps find why pods are evicted or unable to run and separates a single overloaded computer from a wider capacity problem.

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

Triage Kubernetes Node Pressure 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 10d 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

When to use

Use when nodes show MemoryPressure, DiskPressure, or pods are evicted due to node conditions.

Preconditions

  • You have read access to node and pod data.
  • You can identify the affected node(s) or the evicted pods.

Procedure

  1. Confirm the node condition and the time it started.
  2. Identify impacted workloads (evictions, pending pods, restarts).
  3. Determine whether the issue is a single node or widespread.
  4. Identify top contributors (largest pods, runaway logs, tmpfs, imagefs).
  5. Choose the lowest-risk mitigation that restores capacity.

Decision points

  • Single node only: consider cordon/drain after identifying a safe target.
  • Many nodes: treat as capacity or systemic issue (autoscaling, noisy neighbor policy).
  • Disk pressure: check image garbage, log growth, emptyDir usage.
  • Memory pressure: check memory limits, leaks, and node size.

Verification

  • Node condition clears and stays stable.
  • Evictions stop and pending pods schedule.
  • Workload SLO signals return to baseline.

Rollback / undo

  • If you drained a node and it increases impact, stop draining and rebalance workloads.
  • If you changed resource requests/limits, revert to previous values.

Escalation

  • Platform team for cluster-wide pressure or autoscaler issues.
  • Service owners for runaway resource usage.

Examples

kubectl describe node <node>
kubectl get pods -A -o wide | grep <node>
kubectl get events -A --sort-by=.lastTimestamp | tail -n 50

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.
