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

karpenter 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 501 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design, install, debug, review, plan capacity, audit, migrate, and upgrade Karpenter on EKS.

Verify current stable version before installing (Karpenter uses OCI, not a Helm repo):

crane ls public.ecr.aws/karpenter/karpenter | grep -E '^[0-9]+.[0-9]+.[0-9]+$' | sort -V | tail -5

Pin to the version from that output, e.g.:

helm upgrade --install karpenter oci://public.ecr.aws/karpenter/karpenter --version x.y.z

All guidance targets the karpenter.sh/v1 API. The v0.x Provisioner/AWSNodeTemplate API was removed in v1.0 — if you are on v0.x, use migrate mode first.


Interactive Wizard (fires when no arguments are provided)

When invoked with no arguments, ask before proceeding:

Q1 — Mode?

What do you need?
  1. generate — design NodePool and EC2NodeClass from requirements
  2. debug    — diagnose why nodes are not provisioning or pods are stuck Pending
  3. review   — production-readiness review of existing NodePool/EC2NodeClass
  4. audit    — reconstruct scale-out/scale-in history and explain why it happened
  5. plan     — predict what Karpenter would provision for a given workload before deploying
  6. migrate  — move from Cluster Autoscaler to Karpenter
  7. upgrade  — upgrade Karpenter version (including v0.x → v1.x CRD migration)

Enter 1–7 or mode name:

Q2 — Environment context (ask after mode, one question at a time):

1. EKS cluster version?  (e.g. 1.29, 1.30, 1.31)
2. Karpenter version currently installed (or target version for fresh install)?
3. Identity method for Karpenter controller?
     a) EKS Pod Identity  (recommended, requires EKS 1.24+)
     b) IRSA              (IAM Roles for Service Accounts)
4. Is this a private cluster (no public API endpoint)?  [yes/no]
5. Do you use Spot instances?  [yes / no / mixed]
6. Are you migrating from Cluster Autoscaler?  [yes/no]

Use the answers to set defaults for every section below. If the user pastes a manifest or error, infer as much as possible and skip questions already answered.

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.
