  • DSLs Are a Waste of Time
    2 projects | news.ycombinator.com | 4 Sep 2023
    I hate yaml with a passion. It marginally better than xml for reading (wins huge on comment syntax) and worse for everything else. It makes zero sense we somehow ended up with it as standard configuration serialization format.

    Note yaml is not a DSL. It's a tree serialization format! Everything interesting is happening after it is parsed. Extreme examples point to e.g. github actions conditions.

    Anyway, back on topic - maybe not prolog for CDK, but still quite interesting: Dhall-kubernetes - https://github.com/dhall-lang/dhall-kubernetes

    Dhall provides https://github.com/dhall-lang/dhall-kubernetes which is exactly this: statically type-checked kubernetes config generation.
  • The Dhall Configuration Language
    21 projects | news.ycombinator.com | 14 Jul 2022
    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:


    Although I'm tempted to just stick to Helm here, even though it's less type-safe.

  • Why helm doesn't use a general purpose programming language for defining resources?

    Not Helm directly, but does something like Dhall fit your question? https://github.com/dhall-lang/dhall-kubernetes
  • Dhall configuration language as another way to write manifests for Kubernetes
    2 projects | /r/kubernetes | 4 Apr 2022
    Have you heard about Dhall? It’s a programming language used for generating configuration files for a variety of purposes. One of them is to replace old and limited formats such as JSON and YAML. It is DRYable, secure, and even suitable for creating K8s manifests. The latter option isn’t something for anyone: you have to learn a new language and deal with its peculiarities, but it might be really helpful when you have tons of YAML configs. I’ve recently made a short intro to Dhall for K8s in this review.

    Best thing is Dhall that I am aware of. Same situation, working as a consultant, forced to use broken things.


  • Write Gitlab CI Pipelines in Python Code

    Lets look at a specific example. Take Kubernetes: everything is yaml, with complete schemas, all the way down. From your perspective this is configuration utopia, right? Meanwhile back in reality k8s is the poster child of "yaml hell". From the day it was released, people took one look at it, gave it a giant NOPE and instantly spawned half a dozen templating languages. The most popular of these is helm, which has a terrible, no good, very bad design: full of potential injection attacks from purely textual string substitution, manually specified indentation to embed parameterized blocks, virtually no intermediate validation, no way to validate unused features, etc etc

    Compare to dhall which publishes a complete set of dhall-k8s schema mappings which enables you to factor out any design you want down to as few configuration variables as you like, while validating the configuration generators themselves at design time. https://github.com/dhall-lang/dhall-kubernetes#more-modular-...

  • INTERCAL, YAML, And Other Horrible Programming Languages
    12 projects | /r/programming | 25 Feb 2021
    The solution I like is Dhall. They even have a Kubernetes solution that will catch a lot of issues at compile-time, before you try to apply it to Kubernetes. At earthly we aren't actually using it though. Our Kubernetes guru found it to be a bit slow but I am hopeful it or something like it will be the future.
