Automate CI/CD effortlessly with Harness Code Repository Trigger

Table of Contents

Harness Code Repository triggers automate CI/CD pipeline executions based on pull requests, push events, and other conditions. This setup enhances efficiency, ensuring smooth and error-free software delivery. Embrace automation to improve development workflows and integrate seamlessly with DevOps practices.


Speed and innovation drive today's businesses. Developers, armed with tools like CI/CD, GitOps, and IaC, are the architects of this efficiency. Picture software development as baking a cake, where code is the mix, testing is the bake, and deployment is the delicious cake. The CI/CD pipeline acts like a well-organized kitchen, automating each step for efficiency.

Now, think of an automation strategy as a high-tech GPS for businesses, guiding them to complete tasks faster and better. It's about choosing the right tools, training teams, and experimenting with new methods – all to save time, cut costs, and ensure safety. It's like finding the express lane to get things done, making the business run super smoothly.

These triggers are similar to  smart rules, acting as a superhero squad ready to initiate processes precisely when needed. Super efficient and always on point, they're the secret sauce to keep processes running seamlessly.

Discover the simplicity and power of Harness Code Repository triggers in this blog, where we introduce native support for seamless automation in your CI/CD pipeline with triggers.

Automating Pipeline Executions with Harness Code Repository Event Triggers

In the Harness Code repository, pipelines start automatically when important events happen, like pull requests or pushing changes. This ensures that well-configured CI or CD processes start quickly and smoothly.

Harness Code Repository Trigger

Within the Harness Code Repository framework, three key Code Repository events are the stars of the show:

  1. Pull Requests
  2. Push
Harness Code Repository Events

These events are the foundation for our triggers, dictating when the action begins! Additionally, you can choose various actions for a webhook, such as Reopen, Merge, Comment, Create, and Update

Each event becomes more specific with conditions, adding an extra layer of detail to our automation strategy. This includes:

  1. Smart Branch Patterns: Initiating a pipeline happens when the source/target branch name adheres to our predefined pattern. It's like having a rulebook for branches, ensuring a seamless and organized workflow.
  2. File-Driven Automation: Pipelines kick into action when event notifications indicate changes in specific files within the Harness Code Repository. This is a game-changer, especially for monorepos, allowing only the right pipelines to respond efficiently and in a well-controlled manner.
  3. Header Condition: Specify the header attribute for comparison using the format <+trigger.header['key-name']>. For instance, <+trigger.header['X-GitHub-Event']>. This case-insensitive comparison ensures precise evaluation.
  4. Payload Condition: Conditions based on JSON payload values are treated as a data model. Harness listens for events on a JSON payload key, referenced using <+eventPayload.>.
  5. JEXL Condition: Utilize JEXL expressions for referring to payload data and headers, incorporating constants, methods, and operators in Jexl Operator. Conditions are AND, requiring all matches for the Trigger to execute. For advanced operations like OR, NOT, use JEXL Condition, leaving the rest empty.
