I have a github repository connected to my app engine project. I followed this question.
I need an option to do an automatic pull from remote repository on app engine when I push to master.
I already have a php file. Maybe I must delete this file before connection?
Automatically deploying from a git-repository was discontinued a while ago! The way to go now is hosting your own continuous delivery-system, i.e. Jenkins on a Compute Engine instance. More information here: http://stackoverflow.com/a/38385874/198996
