By default, the same pipeline can be run multiple times at once.

In a CDS Workflow, you can limit running a pipeline to one at a time.

Click on the pipeline → Edit the pipeline context → enable “Limit one run at run time”

Pipeline Mutex

Examplary use case: run an integration test once on a particular environment.

To configure a Mutex with the configuration as code, use the boolean property one_at_a_time in the workflow definition file, in a pipeline context section: Mutex configuration as code example.
