GitHub Actions is a prominent automation and CI/CD engine integrated into GitHub, allowing developers to create and share individual tasks, known as actions, on GitHub Marketplace. This open-source ecosystem recently celebrated the milestone of 10,000 published actions, providing developers with diverse options for tasks such as linting, testing, deploying applications, and connecting to third-party services. Developers can discover, fork, and edit actions or create new ones using GitHub's templates. GitHub Enterprise Server users can also participate through GitHub Connect, benefiting from hundreds of actions developed by GitHub Technology Partners. These partners offer reusable components for CI/CD, security, and automation workflows. Verified creators, identified with a badge, indicate a trusted level of action quality. Developers interested in publishing an action can do so by drafting a release, accepting marketplace terms, and completing a few simple steps. GitHub encourages innovation and collaboration, inviting developers and partners to contribute to the growing number of actions and explore further integration possibilities through various resources.
