Elements of a CI/CD pipeline

The steps that form a CI/CD pipeline are distinct subsets of tasks grouped into what is known as a pipeline stage. Typical pipeline stages include:

• Build - The stage where the application is compiled.
• Test - The stage where code is tested. Automation here can save both time and effort.
• Release - The stage where the application is delivered to the repository.
• Deploy - In this stage code is deployed to production.

Validation and compliance - The steps to validate a build are determined by the needs of your organization. Image security scanning tools, like Clair, can ensure the quality of images by comparing them to known vulnerabilities (CVEs).
