GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that allows you to automate your build, test, and deployment pipeline. It is a platform that automates the build, test, and deployment of software, and allows you to run any arbitrary code on your repository when a specific event happens. You can create workflows that build, test, and deploy your code right from GitHub. GitHub Actions connects all of your tools to automate every step of your development workflow.
An action is a custom application for the GitHub Actions platform that performs a complex but frequently repeated task. You can write your own actions, or you can find actions to use in your workflows in the GitHub Marketplace. Actions are easy to set up and integrate, and they speed up software development by creating a standardized and secure software delivery pipeline.
GitHub Actions can be used to integrate and deploy code changes to a third-party cloud application platform as well as to automate workflows across issues, pull requests, and more. It allows you to quickly implement a build, test, and deploy pipeline. You can use GitHub Actions to build powerful CI/CD capabilities right beside your code, and you can even combine them for a custom workflow.
In summary, GitHub Actions is a platform that allows you to automate your build, test, and deployment pipeline, and to run any arbitrary code on your repository when a specific event happens. It provides a standardized and secure software delivery pipeline, and allows you to quickly implement a build, test, and deploy pipeline.
