GitHub Actions is a CI/CD pipeline service that allows developers to run build, testing, and deployment jobs from inside GitHub, providing powerful and affordable infrastructure for static sites without any infrastructure cost. It has removed limitations of traditional GitHub Pages, allowing users to trigger builds every time their team publishes content. This can be achieved by combining GitHub Actions with Contentful's webhook features, enabling a seamless integration between the two platforms. By following the steps outlined in this article, developers can configure GitHub Actions to build and deploy static site generators such as 11ty, Gatsby, or Flask-Frozen, and use GitHub Pages to host their sites. The process involves creating a workflow file, adding an SSH Deploy key, and configuring environment variables using GitHub Secrets, allowing users to automate the deployment of their static sites with ease.
