Full tutorial on the Nikola blog: Automating Nikola rebuilds with GitHub Actions

Short version:

1. Create a repository with a Nikola site.
2. Configure nikola github_deploy. Build and deploy your site locally first.
3. Ensure the correct branch for deployment is set on GitHub (repository settings). Refer to this guide.
4. Create a .github/workflows/main.yml file with the Sample Workflow.

on: [push]

jobs:
  nikola_build:
    runs-on: ubuntu-latest
    name: 'Deploy Nikola to GitHub Pages'
    steps:
    - name: Check out
      uses: actions/checkout@v2
    - name: Build and Deploy Nikola
      uses: getnikola/nikola-action@v3
      with:
        dry_run: false

• dry_run - if set to true only page build is performed, deploy is skipped

By default, the action will install the latest stable release of Nikola[extras]. If you want to use the bleeding-edge version from master, or want to install some extra dependencies, you can provide a requirements.txt file in the repository.
