Build Pipelines

A Bitrise Pipeline is the top level of our CI/CD configuration. Pipelines can be used to organize the entire CI/CD process and to set up advanced configurations with multiple different tasks running parallel and/or sequentially. 

A Pipeline’s building blocks are:

  • Steps: Blocks of script execution, each defining a single task in a CI/CD process.

  • Workflows: Collections of Steps. When a build of an app is running, the Steps will be executed in the order that is defined in the Workflow.

  • Stages: Collections of Workflows. A Stage can contain multiple Workflows which all run in parallel in the same Stage. If all Workflows are successful in a Stage, the Pipeline moves on to the next Stage. If any of the Workflows fail, the Pipeline ends without running the other Stages unless you configure a given Stage to always run.

In this section:

A Step is a block of script execution that encapsulates a build task on Bitrise: the code to perform that task, the inputs and parameters you can define for the task, and the outputs the task generates.

A Workflow is a collection of Steps, Environment Variables, and other configurations. When Bitrise starts a build, it runs one or more Workflows according to the configuration defined in the bitrise.yml file.

A Stage is a collection of Workflows. Stages are the top-level building blocks of Pipelines. A Stage can contain multiple Workflows, which all run in parallel in the same Stage. If all Workflows are successful in a Stage, the Pipeline moves on to the next Stage. If any of the Workflows fail, the Pipeline ends without running the other Stages unless you configure a given Stage to always run.
