This was originally a problem for me, since we have 300+ microservices and projects that all need some of the same environment variables. But then I figured out that the v2 API allows for the creation of environment variables via the REST API. I wrote a quick node application that used the API to stick environment variables into the project, and I’ve found this to actually be better than the old import functionality because I can run it from the command line.
Would LOVE the ability to create/provision projects via the command line, so I could 100% automate the creation of a new project from start to finish. But the environment variables endpoint was big for us.
