info

Harness variable expressions are not supported in triggers for pipeline or stage variables.

Requirements​

Make sure that you have met the following requirements:

  • You have a Harness pipeline with a CD stage.
  • You have set the service and infrastructure as runtime inputs so that you can provide the value in Trigger> Configuration tab.

Execute a specific pipeline stage using triggers​

  1. Select a pipeline whose stage you want to execute using triggers.

  2. Make sure that the Selective Execution Settings> Allow selective stage(s) executions? in Advanced Options of the pipeline is set to Yes.

  3. When you create a trigger, in the Configuration tab, select the stages you want to execute.

Here is a sample trigger YAML:

trigger:
name: stage3Trigger
identifier: stage3Trigger
enabled: true
description: ""
tags: {}
stagesToExecute:
  - stage3
orgIdentifier: NgTriggersOrg
projectIdentifier: viniciusTest
pipelineIdentifier: ThreeStagesPipeline
source:
  type: Webhook

    spec:
      payloadConditions: []
      headerConditions: []
inputYaml: |
  pipeline:
    identifier: ThreeStagesPipeline
    stages:
      - stage:
          identifier: stage3
          type: Custom
          variables:
            - name: stage3var
              type: String
              value: stage3Var
