Deleting a pipeline
If your role has the appropriate permission, you can delete a pipeline. When you delete a pipeline, its associated application packages are not removed from the repositories that the pipeline is configured to use.
To delete a pipeline, do the following steps:
If the pipeline is not open, in the navigation pane of Deployment Manager, click Pipelines and then click the name of the pipeline.
Click the Actions menu, and then click Delete for the pipeline that you want to delete.
In the Delete pipeline confirmation dialogue box, click Delete to confirm.
