Can you add a github action to run renovate? https://github.com/renovatebot/github-action

[Migelo]

Something that runs every 15 minutes like this? Happy to do it!

name: Renovate
on:
  schedule:
    # The "*" (#42, asterisk) character has special semantics in YAML, so this
    # string has to be quoted.
    - cron: '0/15 * * * *'
jobs:
  renovate:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/[email protected]
      - name: Self-hosted Renovate
        uses: renovatebot/[email protected]
        with:
          configurationFile: example/renovate-config.js
          token: ${{ secrets.RENOVATE_TOKEN }}

I never knew one can run renovate as an action, I've always just let it run on its own accord, what benefits do you recon this brings?

[MisterTea]

"let it run on its own accord"

What does this mean? I assumed that without a GitHub action I would need to run some command regularly to get updates.

[Migelo]

It just triggers every so often on its own. Without a schedule I guess it runs when the load on the bot is low? After adding renovate.json you simply need to enable https://github.com/apps/renovate for this repo and that is it, no gh action needed.

[MisterTea]

Oh! That's the part I was missing. Ok, with the GitHub hook we don't need an action.

[Migelo]

Great. Then the only thing you need to do before merging this is to add the renovate GitHub app I linked above to this repo.

Thanks!!
