Which statement is true regarding Continuous Delivery pipelines?

Continuous Delivery pipelines are essential for automating the process of building, testing, and deploying applications in a controlled and reproducible manner. In the context of Tekton, which is a powerful open-source framework for creating CI/CD (Continuous Integration/Continuous Delivery) systems, the way pipelines are defined is crucial to understand.

Tekton pipelines are specified in YAML, which is a human-readable data serialization format often used for configuration files. YAML's simplicity and clarity make it a preferred choice for defining the configuration for automation tasks in modern DevOps practices. By using YAML, developers can structure their pipeline definitions intuitively, making it easier to manage dependencies, specify stages, and configure tasks within the pipeline.

The use of JSON or XML for defining Tekton pipelines is less common, as these formats tend to be more verbose and complicated, making them harder to read and edit than YAML. Additionally, specifying pipelines graphically would not align with the design philosophy of Tekton, which emphasizes code-driven infrastructure as part of the DevOps practices. Instead, Tekton encourages the definition of pipelines in a declarative manner via configuration files, allowing for version control and easier collaboration among teams.
