@readystack/base-image-eol-lint

Base Image EOL Lint - Dockerfile and CI end-of-life check

Marks every base image in your Dockerfiles, compose files and CI workflows whose security patches have already stopped - or stop before 13 November 2026 - and prints the tag that replaces it.

Install

npx @readystack/base-image-eol-lint file

Node 18+. The same 21 rules as the VS Code extension, from a terminal or CI.

Free

• Checks the file you have open against all 21 rules and shows every out-of-support image with the tag that replaces it and how long it has been unpatched - no key, no limit, no watermark.
• --rules lists every rule

With a licence ($29 once)

• Scans every Dockerfile, compose file and workflow in the repository at once, writes a dated CSV/JSON/HTML report, and prints machine-readable output so CI fails the build before an unpatched base image ships.
