CI/CD is a set of practices and processes aimed at automating and accelerating software delivery. It is a methodology that enables development teams to frequently and reliably make changes to code, test them, and deploy the finished product.
The abbreviation stands for:
-
CI (Continuous Integration): Practice of frequently merging code changes from different developers into a shared repository (usually main or master branch). Each merge triggers an automated build, testing (unit, integration tests, etc.), and static analysis.
-
CD (Continuous Delivery): Extends CI by automating the release preparation process. After successful integration and testing, the code is automatically packaged and prepared for deployment. Deployment decision is made manually.
-
CD (Continuous Deployment): Further automation where, after successful build and test, code is automatically deployed to production without manual intervention. Requires high automation level and confidence in testing.
Advantages of CI/CD:
- Faster and more frequent deployment of new features.
- Reduced risk of deployment errors.
- Improved code quality through automated tests.
- Quick detection and fixing of defects.
- Better collaboration between development and operations teams.
- Increased predictability and reliability of releases.
Tools used in CI/CD include:
- Version control systems (Git, SVN).
- Build tools (Maven, Gradle, Ant).
- Automated testing tools (JUnit, TestNG, Selenium).
- CI/CD servers (Jenkins, GitLab CI, GitHub Actions, CircleCI, Travis CI).
- Configuration management tools (Ansible, Chef, Puppet).
- Containerization tools (Docker).
- Container orchestration platforms (Kubernetes).
