Realizing development workflows

Continuous Delivery pipelines consist of several pipeline build steps that are executed in sequence or in parallel, respectively. All the steps are executed as part of a single build. Builds are usually triggered by committing or rather pushing code changes into version control.

The following examines the aspects of a Continuous Delivery pipeline. These general steps are indifferent to the used technology.

The following diagram shows a high-level overview of a simplified Continuous Delivery pipeline. The steps are executed in a Continuous Integration server and use external repositories such as version control, artifact, and container repositories:
