GitHub Actions
GitHub Actions brings CI/CD automation directly into GitHub – triggering workflows on every pull request, commit, or release without leaving the repository.
What Is GitHub Actions?
GitHub Actions is a CI/CD automation platform built into GitHub that enables developers to define and run workflows triggered by repository events such as pull requests or commits. Workflows are defined in YAML configuration files and can execute any sequence of steps – building, testing, deploying, or triggering external tools – on GitHub-hosted or self-hosted runners.
Before integrated CI/CD platforms like GitHub Actions, teams connected separate CI services to their repositories through webhooks and API integrations. GitHub Actions internalised this capability – making it possible to define the full automation workflow in the same repository as the code it builds and tests, without managing a separate CI service.
GitHub Actions workflows are triggered by events: a pull request is opened, a commit is pushed to a branch, a release is tagged, or a scheduled time is reached. Each event can trigger one or more workflows, each composed of jobs that run in parallel or sequentially, each containing steps that execute scripts, shell commands, or reusable actions from the GitHub Marketplace.
AI tools like Gitar operate within GitHub Actions workflows – running as a step in the CI pipeline with access to the code, test results, and logs generated by earlier steps. This integration allows AI agents to perform analysis and apply fixes within the same environment where the failure occurred, without requiring external coordination.
