Adding suggestion to opensource the dsiprouter-terraform repo.
We had discussed this already @mackhendricks, the value add we provide from the images is we have fully tested them and they are one-click deploy for users.
I don't think putting our terraform deployment scripts here will drain revenue from the target user base, as developers working in our ecosystem will already have their own pipelines and images and end-users are not going to be setting up terraform and using them anyways.
