Show HN: Fail CI when your stack runs end-of-life software

Endoflife-ai released eol-check, a zero-dependency GitHub Action that fails CI builds when repositories run end-of-life software, scanning runtime versions from files like .nvmrc, .python-version, and Dockerfile base images against endoflife.ai data. The action, available at endoflife-ai/eol-check@v1, requires no API key or configuration, and supports 500+ products via a products input, with options to fail on 'eol' or 'approaching' and warn within a configurable number of days.

A zero-dependency GitHub Action that scans your repo for runtime versions .nvmrc , .python-version , .ruby-version , go.mod , package.json engines, Dockerfile base images and checks each one against endoflife.ai https://endoflife.ai . Anything past end of life fails the build with a file-anchored annotation; anything close gets a warning and a date. No API key, no configuration required. - uses: endoflife-ai/eol-check@v1 That's the whole integration. A fuller example: name: EOL gate on: pull request: schedule: - cron: '0 6 1' weekly — EOL dates pass whether or not you push code jobs: eol: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - uses: endoflife-ai/eol-check@v1 with: products: 'postgresql:14, kubernetes:1.32' things not visible in the repo fail-on: 'eol' or 'approaching' / 'never' warn-days: '90' | Source | Product | |---|---| .nvmrc , .node-version , package.json engines.node | Node.js | .python-version | Python | .ruby-version | Ruby | go.mod go 1.x | Go | Dockerfile FROM images root + 2 levels | node, python, ruby, golang, php, nginx, postgres, mysql, mariadb, redis, mongo, alpine, debian, ubuntu | Anything else — databases, OSes, appliances, 500+ products — via the products input as slug:version pairs.
