Why Are My Build Pipelines Triggered Multiple Times in Azure DevOps?

If you're using Azure DevOps and have set up different build pipelines for various branches within the same repository, you might have encountered a frustrating issue. Upon pushing a specific tag, instead of triggering just one designated build pipeline, all your configured pipelines spring into action. This guide will help you understand why this happens and how you can effectively resolve it.

The Problem

You have a repository structured as follows:

You've created build pipelines intended to trigger under specific circumstances:

The dev pipeline should start when a tag that starts with dev-v* is pushed.

The ops pipeline should trigger for ops-v* tags.

The qa pipeline is linked to tags beginning with qa-v*.

However, what's going wrong is that when you push something like dev-v1.0.0, not only does the dev pipeline start, but all others do too. This confusion can be overwhelming, especially if you're new to Azure DevOps.

Identifying the Issue

The root of the problem often lies in the configuration of the YAML files responsible for defining your pipelines. Specifically, if each branch's YAML configuration file has the same name, Azure DevOps may not correctly distinguish between them during tag pushes.

YAML File Structure Example

When your repository consists of YAML files named the same across different branches:

All pipelines are triggered regardless of the tag being pushed.

The Solution

Step 1: Rename Your YAML Files

A straightforward way to rectify this situation is to ensure that each YAML file has a unique name corresponding to its branch. Here’s an example of how you might structure your files instead:

This way, there’s a clear distinction between each pipeline, which can help Azure DevOps understand which one to trigger based on the tag that is pushed.

Step 2: Update Your Pipeline Configurations

After renaming the YAML files, you'll need to create new pipelines that point to the new file names. This will ensure the build system knows where to look for the correct configurations for each branch.

Step 3: Validate the Changes

Once you've updated the names and configured the pipelines, test by pushing your tags again. Monitor the triggered pipelines to confirm that only the intended ones are activated based on the tag.

Conclusion

Dealing with multiple build pipelines being triggered can be a frustrating issue, particularly for those just starting with Azure DevOps. However, by ensuring that your YAML files are uniquely named for each branch, you can streamline your CI/CD process and trigger only the relevant pipelines during tag pushes.

If you continue to have issues or have any questions, don’t hesitate to seek further guidance or support, and happy coding!
