I think some of it is automated already? Yesterday I logged into the bot account and saw some activity where the bot sends PRs to the official Docker image library. Seems like we could also automate bumping the Node.js versions when there's a new release.

Funny enough I wrote a script a couple weeks ago to fetch the latest versions of all maintained release lines:

'use strict'

import { default as nv} from '@pkgjs/nv';
import { default as semver } from "semver";
import { writeFile } from 'fs/promises';

const versions = (await nv('maintained')).map(obj => obj.version)
  .sort(semver.compare)

console.log(versions.join('\n'))

Could be adapted to whatever we need for this repository.

Actually, looks like the repository already has a script to update all images? https://github.com/nodejs/docker-node/blob/master/update.sh

If so, we could have a daily Action that runs the script, and if the repository has any changes pushes it and creates a PR (or just pushes to the default branch, whichever works best).

Yeah, an action running the update script should be fine. One snag is that we need to wait for the musl builds to complete so we can get them from https://unofficial-builds.nodejs.org/download/release/. Usually they are available not long after the official builds (I think about an hour?). We should probably just make the update script fail if it's not available while official builds are.

At that point, the bot could auto merge green PRs and the usual build from master would open a PR (the last part is implemented today)

Semi-related is #1194 which converts much of our CI from Travis to GH Actions

Oh, and /cc @nodejs/docker

Just pointing out that adding a scheduler Action should be possible without #1194, especially since that's a long PR and the scheduler Action would probably be short.

For sure, I just assume the action (or whatever) for auto-merging PRs would work better if it just checked that all other workflows passed successfully rather than pinging travis. I guess we can just check the status tho, so maybe there's no difference 🙂

Took a quick kick at the cron action in #1314
