⁠AKS LTS & EKS Extended Support Lint for Terraform

Terraform EKS and AKS version check: sample clusters.tf on 2026-09-27 — $2,256 extra on EKS 1.32 since 2026-03-23, $3,660 on 1.31 since 2025-11-26, $5,916 total; 9 rules

⁠Run

docker run --rm -v "$PWD":/work getreadystack/aks-eks-support-cliff-lint /work/file

The same 9 rules as the VS Code extension, in a container. Mount a folder on /work.

⁠Free

• Lint the open .tf file with all 9 rules: every EKS and AKS cluster block checked against the dated calendars, with the dollars already billed.
• --rules lists every rule

⁠With a licence ($29 once)

• Scan the whole workspace and export a per-cluster CSV of fees, cliff dates and fixes for a platform or FinOps review.

docker run --rm -e READYSTACK_LICENSE=<key> -v "$PWD":/work getreadystack/aks-eks-support-cliff-lint --dir /work --ci

Amazon EKS bills $0.60 per cluster-hour in extended support against $0.10 in standard support, so one cluster left on an old version costs $365 a month or $4,380 a year extra; AKS Premium tier for LTS is $0.60 against $0.10 for Standard.
