ADF git mode recommends publishing to Master branch(or a fix branch which usually is protected from check-ins). Since Master is usually protected from check-ins and only pull requests are allowed, how would the publish work?
Master branch is used to publish ADF to adf_publish branch. In short, this process converts several json files into ARM-template json files stored in adf_publish branch. Other working banches need to be merged into Master branch and then be published together in Master branch.
