Using Terraform/HCL as a pre-processor to generate any of the other formats seems like the best now. It is - No footguns (compared to the alternatives) - Basic text-templating - Can do structural manipulations of data. As opposed to many other config-generators that only do string-interpolation of text. Helm and j2.... kill me please, who ever thought this was a good idea - Basic looping, transformations and function calls. Without falling into the full imperative programming language trap. Configuration is still deterministic and directed. - Supports loading data from other sources - Supports comments
