Terraform 0.9
I was initially a huge fan but now I hate it. It re-invents so many unnecessary wheels that it is downright obnoxious. There are no loops, if statements, variables. Things that have been in programming languages since day 1. It re-invents modules, badly. Has weird hacks like null resources and external data providers to get around shortcomings in their "declarative" model. And a few other things I'm forgetting. Oh, now they're adding "environments". That's just dandy because they got everything else so right.Every place I've seen Terraform used invariably runs into these shortcomings and the workarounds range from using Erb and Jinja templates to generate Terraform templates to just ditching it entirely and using home-grown solutions. Terraform should have been a library in an actual programming language instead of a gimped external DSL that re-invents the wheel.
