How is automation of build and deployment of software products implemented within CI/CD?

Build and deployment automation in CI/CD is implemented through the creation of pipelines that sequentially perform stages: code compilation, testing, packaging, and deployment. A version control system (e.g., Git) is typically used, which triggers the build process upon commit.

Main steps:

• Build: compilation and preparation of artifacts.
• Testing: automatic execution of unit, integration, and other tests.
• Artifact publication: uploading to a repository or storage.
• Deployment: automatic deployment to test or production servers.

Tools such as Jenkins, GitLab CI/CD, GitHub Actions, CircleCI, etc., are used for implementation. Scripts and configuration files describe the sequence of actions, which helps eliminate manual labor and speed up the release of new versions.
