Dhall is my favorite configuration language that I never get around to using. I manage DNS in Terraform, and since every Terraform provider uses different objects definitions, and every object definition is rather verbose, Dhall would be a way to specify my own DRY types and leave the provider-specific details in one place. Adding new DNS entries and moving several domains between providers would be a matter of changing fewer lines. Dhall also has Kubernetes bindings: https://github.com/dhall-lang/dhall-kubernetes https://github.com/dhall-lang/dhall-kubernetes Although I'm tempted to just stick to Helm here: even though it's less type-safe, Dhall's verbosity makes me reconsider. I'd like to hear if anyone has used dhall-kubernetes if they like it.

I use tanka/jsonnet and cringe everytime I read a helm chart. Type safety would be nice, but the k8s api can verify the validity on the server. https://tanka.dev/ https://tanka.dev/

  Tanka is what I want to use when the time comes. Are there any pitfalls you have learned to avoid?

    I think it might still have issues figuring out that it needs to apply CRDs first: https://github.com/grafana/tanka/issues/246 https://github.com/grafana/tanka/issues/246 Besides that, I found it super-handy for deploying https://github.com/prometheus-operator/prometheus-operator https://github.com/prometheus-operator/prometheus-operator and https://github.com/kubernetes-monitoring/kubernetes-mixin https://github.com/kubernetes-monitoring/kubernetes-mixin LE: The "garbage collection" feature is very interesting, but I didn't get to experiment with it enough yet: https://tanka.dev/garbage-collection https://tanka.dev/garbage-collection

  tanka helped me make peace with k8s (yaml) or at least made for a good learning environment for k8s than the other options. Wonder about other peoples experience or their rite of config tool passage

We use https://github.com/octodns/octodns https://github.com/octodns/octodns for some of our DNS records. It's flexible, much faster than Terraform for thousands of records, and the maintainer Ross has been responsive on issues and pull requests. Also see Cloudflare's blog for how they use it
