Factor.io might be a good fit for you. I am the co-founder/CEO and I hate self promoting, but in this case I think that we can help. We provide a way for you to create workflows like the one you described. It's kind of like IFTTT/Zapier for Dev/DevOps. But we support running numerous actions, custom code for new extensions, and more complex operations. Still in private beta, but would love to help out and get you to test it out. Shoot me an email maciej@factor.io.
