When setting up a pipeline, it's helpful to know a few related terms.

• Pipeline:

  A pipeline consists of stages and steps. It defines the process to build, test, and deploy your code. Rancher pipeline uses the pipeline as code model—pipeline configuration is represented as a pipeline file in the source code repository, using the file name .rancher-pipeline.yml or .rancher-pipeline.yaml.

• Stages:

  A pipeline stage consists of multiple steps. Stages are executed in the order defined in the pipeline file. The steps in a stage are executed concurrently. A stage starts when all steps in the former stage finish without failure.

• Steps:

  A pipeline step is executed inside a specified stage. A step fails if it exits with a code other than 0. If a step exits with this failure code, the entire pipeline fails and terminates.

• Workspace:

  The workspace is the working directory shared by all pipeline steps. In the beginning of a pipeline, source code is checked out to the workspace. The command for every step bootstraps in the workspace. During a pipeline execution, the artifacts from a previous step will be available in future steps. The working directory is an ephemeral volume and will be cleaned out with the executor pod when a pipeline execution is finished.
