 ### Image Creation Automation
 
 - Every 15 minutes, the [workflow](https://github.com/nodejs/docker-node/blob/main/.github/workflows/automatic-updates.yml) within the [nodejs/docker-node](https://github.com/nodejs/docker-node) repo [checks](https://github.com/nodejs/docker-node/blob/main/build-automation.mjs) for new versions of Node.js [published to the website's `index.json` file](https://nodejs.org/download/release/index.json).
-  - If found, it also checks for an [unofficial musl/Alpine build](https://unofficial-builds.nodejs.org/download/release/index.json).
   - If found, the [update script](https://github.com/nodejs/docker-node/blob/main/update.sh) runs
   - The workflow opens a pull request either automatically via [nodejs-github-bot](https://github.com/nodejs-github-bot) or in some cases manually, such as when there is a new major release.
 - Another [workflow](https://github.com/nodejs/docker-node/blob/main/.github/workflows/official-pr.yml) detects the merger of these pull requests and opens a pull request to [docker-library/official-images](https://github.com/docker-library/official-images).

-For Node.js security releases, Debian-based `node` images may be published in advance
-of Alpine-based images. To build an Alpine-based `node` image requires
-a `musl` build. This may not initially be ready at Node.js release time.
-When processing non-security Node.js releases, the build process will wait for
-the `musl` build before proceeding with Debian- and Alpine-based images.
