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

> Runs the same checker as our npm package on a Node.js runtime that pip installs for you (`nodejs-wheel-binaries`) - no system Node.js needed. Your files are checked locally.

![Dockerfile EOL Lint - base image end-of-life (FROM tags) — finds the line](https://getreadystack.com/img/promo/base-image-eol-lint_demo.gif)

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

```
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.

```
base-image-eol-lint --dir ./templates --report html --out report.html
```

Snyk's Team tier is $25 per contributing developer per month.

```json
{ "mcpServers": { "base-image-eol-lint": { "command": "base-image-eol-lint", "args": ["--mcp"] } } }
```

Tools: `check_text` and `check_file` (free) · `check_dir` (licence). The agent gets every finding with the line number.

## Use in CI

```yaml
- name: Base Image EOL Lint - Dockerfile and CI end-of-life check
  run: pip install rulestamp-base-image-eol-lint && base-image-eol-lint --dir . --ci
```


The folder sweep, reports and CI mode need one licence — one payment, no subscription. Set `READYSTACK_LICENSE=<key>` or run `--license <key>` once.
