Wasted a day fighting the breaking changes and new bugs over at Google Cloud Build's GitHub integration (alpha)... I had a good CI/CD flow that is broken now because of the change... anyway, I will switch over to Circle CI... have had enough of alpha bugs for the next few months... Google Cloud Build does have an attractive pricing (free 120 build minutes per day) and a whopping 10 concurrent builds limit... but it is only supported by the community and you don't get a lot of active developers feedbacks...
