Triggers

When code is pushed to a repository, a pull request is opened, or a tag is created, Harness Open Source can automatically trigger pipeline execution.

When creating a pipeline, Harness Open Source automatically creates a default trigger for you. You can customize this trigger, or create additional triggers.

Create a trigger

1. Navigate to your pipeline, then select Pipeline Settings

2. Open the Triggers tab and select New Trigger

3. Give the trigger a name and select your desired trigger options

4. Select Create

Your trigger will appear in the list.

Conditions

By default, all steps in your pipeline will run when triggered. You can limit pipeline step execution at runtime with conditions.

Harness Open Source supports multiple pipelines per repository. Creating a pipeline per trigger event (push, pull request, tag) can reduce the need for conditions.

This pipeline runs the test step only for pull request events.

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: test
        type: run
        when: build.event == "pull_request"
        spec:
          container: golang
          script: |-
            go build
            go test

This pipeline runs the test step only for pull request created actions.
