Trigger Azure DevOps build pipeline with commit message

I am using Azure DevOps to build an application with both a UI and a Backend component. Both components are stored in the same project on GitLab. I need to set up two build pipelines, one for UI changes and one for backend changes.

I would like to be able to trigger the appropriate pipeline based on the commit message. For example, if a UI change is made, the commit message should contain the keyword “UI_CHANGES” to trigger the UI build pipeline.

Is it possible to use Git tags for this, or are there any other ideas?

Yes, it is possible to use Git tags for this. You can create a Git tag containing the keyword “UI_CHANGES” and set up a pipeline trigger to run when that tag is pushed to the repository. Alternatively, you could also use a custom Git hook to check the commit message for the keyword and trigger the appropriate pipeline accordingly.
