Staging preview setup

Staging preview setup

Use this workflow to deploy a preview of feature branches without merging to main.

One-time GitHub setup

  1. Open Settings → Pages in the repo.
  2. Under Build and deployment, set Source to GitHub Actions (not “Deploy from branch”).
  3. Keep main as your production branch — production can stay on legacy branch deploy until you migrate.

Add the workflow (requires workflow scope)

Copy this file to .github/workflows/staging-preview.yml in the repo (via GitHub web UI or a token with workflow scope):

name: Staging Preview

on:
  pull_request:
    branches: [main]
  push:
    branches: [feature/about-page-redesign]
  workflow_dispatch:

permissions:
  contents: read
  pages: write
  id-token: write

concurrency:
  group: pages-preview-$
  cancel-in-progress: true

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    environment:
      name: github-pages
      url: $
    steps:
      - uses: actions/checkout@v4
      - uses: ruby/setup-ruby@v1
        with:
          ruby-version: '3.3'
          bundler-cache: true
      - run: bundle exec jekyll build --trace
        env:
          JEKYLL_ENV: production
      - uses: actions/upload-pages-artifact@v3
        with:
          path: _site
      - id: deployment
        uses: actions/deploy-pages@v4

Preview URLs

After the workflow runs:

Context Where to preview
Pull request Deployments check on the PR → preview link (does not replace production)
Branch push Actions run → Deploy preview step → page_url
Project Pages fallback https://corrupted-brain.github.io/blog/about/

Quick manual staging (no Actions)

  1. Open a PR: https://github.com/corrupted-brain/blog/pull/new/feature/about-page-redesign
  2. In Settings → Pages, temporarily set branch to feature/about-page-redesign / / (root).
  3. Preview at https://kailashbohara.com.np/about/ — this replaces live site until you switch back to main.
  4. Switch Pages source back to main when done.

Local preview

git checkout feature/about-page-redesign
bundle install
bundle exec jekyll serve
# http://localhost:4000/about/
