Definition
GitHub Actions is GitHub's built-in CI/CD automation platform that runs workflows — defined as YAML files in a repository — to build, test, and deploy code in response to repository events.
Overview
GitHub Actions lets teams define automation as YAML workflow files stored directly alongside their code, triggered by events like a push, a pull request, a scheduled time, or a manual dispatch. Each workflow runs one or more jobs made up of steps, which can run shell commands or call reusable, published "actions" that wrap common tasks like setting up a language runtime, running tests, or deploying to a cloud provider. Because workflows live in the same repository as the code they build and deploy, changes to the pipeline are versioned and reviewed the same way as any other code change. Jobs run on GitHub-hosted runners across Linux, Windows, and macOS, or on self-hosted runners for workloads needing specific hardware or network access, and steps commonly build and push Docker images, run tests, and deploy to Kubernetes clusters or cloud services. GitHub Actions competes with dedicated CI/CD tools like Jenkins and GitLab CI, with the main advantage being tight, native integration with GitHub repositories, issues, and pull requests without needing a separate system. The SkillVeris course CI/CD with GitHub Actions and the companion post CI/CD Explained: Build, Test, Deploy both go deeper into building real pipelines.
