OK, still trying to stand up a deployment. First one failed silently and left the "Submitting Deployment for Template Deployment..." on my portal panel forever. Second one failed within a minute with DNS naming conflict. Maybe third time is a charm. I'm currently using Dokku to run some small apps, and it seems to work well. However, all this magic control panel automation and deployment with weird DSL/JSON scripts causes quite a bit of pain.
