I've used Dhall in production, pushed it fairly hard and can say with utmost certainty it's be an absolute pleasure. We use it as our application configuration format and derive fairly intricate Kubernetes resources from our app config.

Although it is still in it's early days, it still is excellent to use and will only get better with additional tooling.

How does it differ from the CDK/CDK8s/terraform-cdk?

[zingplex]

CDK uses existing fully featured programming languages that can preform side effecting actions thus lacking reproducibility and that are may not terminate. Dhall is a total language, meaning it will always terminate and a pure language, meaning that a function given an input will always yield the same output. That makes the output extremely predictable.
