Trigger pipeline

What it does

This action triggers another pipeline from the same or from another project. The action allows creating waterfall-type of workflows, or to trigger another pipeline in parallel after a specific stage has been completed. It also allows a streamline management of multi-repository applications.

How it works

The action works in a similar way to manual pipeline triggering with clicking the Run button, but it’s done by the action instead.

Good to know

By default, the triggered pipeline is executed with the same revision number as the parent pipeline when both are in the same project. If a pipeline from a different project is selected, it’s always triggered with the HEAD revision. The parent pipeline does not wait for the triggered pipeline to complete by default, but it can be set to wait. Creating loops is not possible. If pipeline X triggers pipeline Y, it won’t be possible to add an action triggering pipeline X in pipeline Y.

Trigger Pipeline Action Features

• Triggered pipeline can be run with the same revision as the parent pipeline or with HEAD when both pipelines are in the same project
• If set, the triggering pipeline can wait for the triggered pipeline to finish before the subsequent actions in the parent pipeline are resumed. This option requires at least two concurrent pipeline executions in a workspace plan. However, when the triggered pipeline fails, the parent pipeline will be marked as failed too.
• The triggering pipeline can pass Environment Variables to the triggered pipeline, you can specify them in the Variables tab. For example, it’s possible to pass the execution ID from one pipeline to another.
• Comment for an execution of the triggered pipeline is settable and accepts ENV VARs. To execute the child pipline with the same comments with which the parent pipeline was executed use $BUDDY_EXECUTION_COMMENT for the Comment.
• Input fields: Comment supports ENV VARs
• The action can be configured in YAML mode. See Trigger pipeline YAML parameters and Trigger pipeline YAML config example
• Buddy's Trigger pipeline API is supported
• The action supports conditional execution: it can be run on each execution, only if there are changes in the repository or specific paths since the last execution, or if an environment variable has a specific value
• Error handling: you can either stop the execution, mark action and pipeline as failed or proceed the execution, mark action as warning and jump to the next action
