Whenever you get a chance for the placing in cypher and pulling from it to the task, but definitely not when you are on PTO! 
I was able to get it to function overall by creating the service account and creating the key and storing it locally. It was a bit of a task due to gcloud commands requiring the projectID and not name, so additional calls were required. Overall, it is working though. I just didn’t know if I could utilize whatever method that morpheus uses already to make it happen instead of going into a custom setup. Thanks!
