Pipeline as Code

Defining CI/CD pipelines in version-controlled files, usually YAML, stored alongside application code.

Definition

Pipeline definitions such as .github/workflows/*.yml, .gitlab-ci.yml, azure-pipelines.yml, buildspec.yml, or a Jenkinsfile are reviewed, versioned, and reused like any other code.

Example

A change to the deployment stage is proposed in a pull request that edits azure-pipelines.yml.

Exam tip

AZ-400 prefers YAML pipelines over classic UI pipelines because they are versioned with the code.
