Create triggers

In Harness, you can create triggers to automatically run your CI/CD pipelines in response to push events in your Harness Code repos.

Currently, Harness Code triggers must be configured in the YAML editor.

1. Go to the pipeline where you want to add a trigger for a Harness Code repository.

2. Make sure your Harness Code repo is the pipeline's default codebase.

3. Select Triggers in the Pipeline Studio header.

4. Select New Trigger, and select the Custom trigger type.

5. Enter a trigger Name and then switch to the YAML editor.

6. Replace the source and inputYaml sections with the following:

     source:
       type: Webhook
       spec:
         type: Harness
         spec:
           type: Push
           spec:
             autoAbortPreviousExecutions: true
             payloadConditions: []
             headerConditions: []
             repoName: ## Provide your Harness Code repository name.
             actions: []
     inputYaml: |
       pipeline:
         identifier: ## Provide the same value as 'pipelineIdentifier'.
         properties:
           ci:
             codebase:
               build:
                 type: branch
                 spec:
                   branch: <+trigger.branch>

7. Save the trigger.

8. To test the trigger, create a PR or push a change to your Code repository.
