I am using Gitlab, Spring Boot and Google Cloud App Engine, Google Cloud mySql.
I have resource bundle files like application-{environment}.yaml for my Spring Boot application.
I don't want to keep the secrets in application-*.yaml files. I wanted those sensitive variables in App Engine's System Environment. But I think there is no Environment Variable support on Google Cloud App Engine.
I wanted to ask if there is a way to do this.. before I completely abandon Google Cloud Platform.
