A simple GitHub Action for producing Jekyll build artifacts compatible with GitHub Pages.

This is used along with actions/deploy-pages as part of the official support for building Pages with Actions (currently in public beta for public repositories).

A basic Pages deployment workflow with the jekyll-build-pages action looks like this.

name: Build Jekyll site
on:
 push:
   branches: ["main"]
permissions:
  contents: read
  pages: write
  id-token: write
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
      - name: Setup Pages
        uses: actions/configure-pages@v5
      - name: Build
        uses: actions/jekyll-build-pages@v1
      - name: Upload artifact
        uses: actions/upload-pages-artifact@v3
  deploy:
    runs-on: ubuntu-latest
    needs: build
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}

To write to a different destination directory, match the inputs of both the jekyll-build-pages and upload-pages-artifact actions.

steps:
  - name: Build
    uses: actions/jekyll-build-pages@v1
    with:
      destination: "./output"
  - name: Upload artifact
    uses: actions/upload-pages-artifact@v3
    with:
      path: "./output"

In order to release a new version of this Action:

1. Locate the semantic version of the upcoming release (a draft is maintained by the draft-release workflow).

2. Prepare a pull request to update action.yml to reference the incoming version, get it approved, and merge it into the main branch.

3. Publish the draft release as a pre-release from the main branch with semantic version as the tag name, with:

   • the checkbox to publish to the GitHub Marketplace checked ☑️
   • ⚠️ AND the checkbox to Set as a pre-release checked. ☑️

4. This will kick off a Docker publishing workflow for the newly created tag. Check the associated workflow run list to verify the new Docker image is created successfully before moving on to the next step.

5. After the Docker image has been created with the new tag, find that same pre-release and edit it. Update it with the checkbox to Set as the latest release checked ☑️ and then publish it again.

6. After publishing it as the latest release, the release workflow will automatically run to create/update the corresponding the major version tag such as v1.

   ⚠️ Environment approval is required. Check the Release workflow run list.
