Introduction

Managing Continuous Integration and Continuous Deployment (CI/CD) in a project involves dealing with various complexities, especially when multiple branches are in play. One common scenario that many developers face is how to control Jenkins checks on feature branches. If you're pushing changes to a feature branch, you might want to skip certain Jenkins stages to save time and resources. This guide will guide you through disabling checks for feature branch pushes while keeping automatic checks intact for your master branch.

Problem Statement

When you work with a git repository that includes a master branch and various feature branches, it's common to have a Jenkins setup that triggers builds on every push or pull request. However, this can lead to unnecessary builds for feature branches, especially if you're still developing and have not merged changes into the master branch yet. The goal is to ensure that only changes on the master branch trigger the Jenkins pipeline stages, while the feature branches can be excluded from specific checks.

Solution Overview

To achieve this, you need to add a condition within your existing Jenkins file that specifies which branches should or should not trigger the execution of certain stages. The example provided here will explain how to implement this in a clear and concise manner.

Step-by-Step Guide

Step 1: Modify Your Jenkinsfile

Locate your Jenkinsfile where your existing stages are defined. Inside this file, you’ll need to add a specific condition that prevents the execution of certain stages when a feature branch is pushed. Here’s how you can do that:

Step 2: Understanding the Code

stage: This defines a single stage in your Jenkins pipeline. You can name it whatever you prefer; in this case, it signifies that the stage won't run for feature branches.

when {}: This block allows you to set conditional behaviors for the execution of the stage.

expression: This part uses a Groovy expression to evaluate whether to run the stage or not. The code checks if the current branch does not (!) contain the word 'feature'. If the branch is the master branch, the stage will run.

steps: This section contains the commands you want to execute during this stage.

Step 3: Validate Your Changes

Once you’ve made these changes to your Jenkinsfile, it's important to validate that your CI/CD pipeline behaves as expected:

Push changes to a feature branch and observe that the defined stages do not execute.

Push changes to the master branch and verify that all stages run as intended.

Conclusion

Disabling Jenkins checks for feature branch pushes not only enhances your workflow but also optimizes your build process. By implementing the conditional expression, you ensure that resources are only utilized when necessary, thus avoiding unnecessary delays during development. With these adjustments made in your Jenkinsfile, you're on your way to a more efficient development cycle.
