How do I configure AWS CodeBuild to build only when push to master branch is made?

I am using a webhook to build my project on push requests. By default, AWS CodeBuild builds on push to every branch, however I would like to limit that to master - to trigger the build ONLY when push to master is made. How do I use the regex patterns to do that?

The AWS documentation is not really specific in terms of how to use the regular expressions there.

Your problem has nothing to do with CodeBuild. You need to configure de "source" stage in your pipeline to listen to master branch. BTW, I didn't downvote. - Héctor
I don't use CodePipeline. I use CodeBuild only, sourcing the code from BitBucket and publishing the artifacts to S3 after the build. - Michał Urbaniak
@MichałUrbaniak any chance you can mark my answer as correct? It will be my first :) - Mark Adamson

Set the HEAD_REF setting to ^refs/heads/master$. They don't explicitly specify it for master branch in the docs but they do show the equivalent for 'branch1'
