Add Resilience Tests to Harness CD Pipeline

The One-Click Harness CD Onboarding feature makes it incredibly easy for Harness CD customers to add resilience testing to their existing pipelines with just one click. The system automatically analyzes your cluster, identifies deployed services, determines appropriate chaos experiments for each service, creates chaos steps with the exact parameters needed, and integrates them directly into your CD pipeline.

Overview​

The automated workflow includes:

  • Cluster Analysis: Scans your target cluster to understand the infrastructure
  • Service Discovery: Identifies all deployed services and their configurations
  • Experiment Matching: Determines which chaos experiments are appropriate for each service
  • Parameter Configuration: Creates chaos steps with exact parameters tailored to your services
  • Pipeline Integration: Automatically adds the configured chaos steps directly into your CD pipeline

Prerequisites​

Before using One-Click CD Onboarding, ensure you have:

  • Harness Continuous Delivery: Active access to the Harness CD module
  • Harness Chaos Engineering: Active access to the Harness Chaos Engineering module

Getting Started​

  1. Navigate to Execution History of your pipeline.

  2. Go to Resilience Tests tab of your pipeline and click on Add Resilience Tests to this Pipeline.

  3. The system will automatically perform the following workflow:

    • Check Infrastructure: Verifies if chaos experiments are already available for your infrastructure

    • Auto-Discovery: If not chaos-enabled, the system discovers services and creates chaos experiments for the infrastructure

    • Create Custom Stage: Automatically creates a new "Resilience Tests" stage in your pipeline

    • Add Chaos Experiments: Automatically adds the appropriate chaos experiments to the custom stage in your pipeline

      Add Resilience Tests to Pipeline

  4. Review the Resilience Tests Added summary:

    • Pipeline: Shows which pipeline the tests were added to (e.g., "cd-deployment - test")

    • Resilience Tests: Lists the specific chaos experiments created (e.g., "nginx-deployment-pod-delete-vhf7p")

    • Targeted Service: Shows the service being tested (e.g., "nginx-deployment")

    • Target Infrastructure: Displays the infrastructure where tests will run (e.g., "testenv64new/testinfra")

    • Click View in Pipeline to see the updated pipeline with the new resilience tests stage

  5. Run the Updated Pipeline:

    • You'll now see your pipeline with the new Resilience Testing stage automatically added between your deployment stages

    • The pipeline shows the complete flow: deployment → resilience testing → additional stages

    • Click the Run button to execute the pipeline with chaos experiments included

    • The resilience tests will run automatically as part of your CD workflow
