Scheduled blog publishing

When I write a new blog entry, I'd like to schedule its publishing since usually write them at night and it's not a good time to make it open. As I write in the last post, this blog is running on GAE and deployed via GitHub Actions when PR is merged. Therefore, scheduling publishing can be done by scheduling merging PRs.

merge-schedule action

Fortunately, there are bunch of good GitHub actions in GitHub marketplace. I found gr2m/merge-schedule-action and it is available in marketplace as merge-schedule.

It's easy to schedule to merge PRs thanks to this action. The YAML file looks like following.

name: Merge Schedule
on:
  pull_request:
    types:
      - opened
      - edited
  schedule:
    # every day 01:30 UTC (10:30 JST)
    - cron: 30 1 * * *

jobs:
  merge_schedule:
    runs-on: ubuntu-latest

    steps:
      - uses: gr2m/merge-schedule-action@v1.x
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

And then, put schedule annotation to description of PR formatted as /schedule YYYY-MM-DD.

That's it!
