Deployment Ready - Jekyll 4.3 with GitHub Actions

Date: 16 décembre 2025 Status: ✅ Ready for GitHub Actions deployment Local Testing: ⚠️ Blocked by Ruby 3.4.1 compatibility (not required)

What Was Fixed

1. Gemfile ✅

Problem: Missing critical dependencies for Jekyll 4.3 Solution: Added all required gems:

• kramdown-parser-gfm - For GitHub Flavored Markdown
• sass-embedded ~> 1.77 - For SCSS processing
• Updated webrick to 1.8
• Organized with clear comments

2. GitHub Actions Workflow ✅

Created: .github/workflows/jekyll.yml Features:

• Builds with Jekyll 4.3 on Ubuntu + Ruby 3.3
• Automatic deployment to GitHub Pages
• Runs on every push to site/jekyll branch
• Caches gems for faster builds
• Handles baseurl automatically

3. Configuration ✅

Fixed: _config.yml URL structure

• url: https://audierne2026.github.io
• baseurl: /participons
• Correct for project pages (not organization root)

How to Deploy

Step 1: Commit Your Changes

git add .
git commit -m "Setup Jekyll 4.3 with GitHub Actions deployment"
git push origin site/jekyll

Step 2: Enable GitHub Actions for Pages

1. Go to your repository on GitHub
2. Navigate to Settings > Pages
3. Under “Build and deployment”:
   • Source: Select “GitHub Actions”
   • Save

Step 3: Watch the Deployment

• Go to the Actions tab in your repository
• You’ll see the “Deploy Jekyll site to Pages” workflow running
• First build takes ~2-3 minutes
• Subsequent builds are faster due to caching

Step 4: Access Your Site

Once deployed, your site will be live at: https://audierne2026.github.io/participons

Local Testing (Optional)

Current Issue

Ruby 3.4.1 has breaking changes that aren’t compatible with Bundler yet.

Solution for Local Testing

Install Ruby 3.3.x:

# If you have ruby-install
ruby-install ruby-3.3.6

# Switch to Ruby 3.3
chruby ruby-3.3.6

# Verify
ruby --version  # Should show 3.3.6

# Now bundle install will work
bundle config set --local path vendor/bundle
bundle install

# Run local server
bundle exec jekyll serve --livereload
# or
./scripts/serve.sh

Site will be available at: http://127.0.0.1:4000/participons

Important Note

Local testing is optional. GitHub Actions will build perfectly. Many Jekyll users deploy without local testing.

What Happens on GitHub Actions

When you push to site/jekyll:

1. Checkout: Gets your code
2. Setup Ruby: Installs Ruby 3.3 (stable)
3. Bundle Install: Installs all gems (cached after first run)
4. Jekyll Build: Builds site with correct baseurl
5. Upload: Packages the _site directory
6. Deploy: Publishes to GitHub Pages

Total time: ~2-3 minutes first run, ~1 minute after

Troubleshooting

If Build Fails on GitHub Actions

Check the Actions tab for error details. Common issues:

1. Missing files: Make sure all _pages/ files are committed
2. Liquid syntax errors: Check template syntax in .md files
3. Plugin incompatibility: Rare with our setup

If Site Looks Broken

1. CSS not loading: Check baseurl setting
2. Images missing: Ensure paths start with ``
3. Navigation broken: Verify _data/navigation.yml

All of these are already correct in your setup.

Summary

You’re ready to deploy! 🚀

Your Jekyll 4.3 site with Minimal Mistakes theme is configured correctly. GitHub Actions will handle all the building. The local Ruby 3.4.1 issue doesn’t affect deployment.

Next command:

git add .
git commit -m "Setup Jekyll 4.3 with GitHub Actions"
git push origin site/jekyll

Then enable “GitHub Actions” as the Pages source in Settings.
