cnab-spec VS tanka

CNAB

Similar to https://cnab.io/ then?

IMO Cloud native application bundle is what you are looking for: https://cnab.io/

have you looked at CNAB ? since it uses standard OCI compliance you can have your entire application bundle on Azure registry (azure registry is OCI 2 compliant registry) and you can get more information about how to do it using ORAS cli

Check https://cnab.io/ and https://porter.sh/

I'm closely tracking an effort by Microsoft that aims to do a lot of what you're describing since I find myself bridging between these tools and deploying stacks that span tools and roles. [CNAB](https://cnab.io/) and the front-running implementation, [Porter](https://porter.sh/), enable one-step infra deployments, packaged as a single OCI-compatible container, with any number of steps, using the best tools for each of those steps. Think of using aws-cli for some initialization step (create or verify presence of a state bucket), applying some terraform to create infra, and finishing with a helm chart to complete deployment of app components. Each stage in a bundle packages not only the code to run it but also the execution binary of the tool that runs it. The spec and porter are still a moving target but it's a promising space and a nice adjacent evolution of the current state of tooling.

I would recommend implementing a similar API to Grafana Tanka: https://tanka.dev

When you "synthesise", the returned value should be an array or an object.

1. If it's an object, check if it has an `apiVersion` and `kind` key. If it does, yield that as a kubernetes object and do not recurse.

Maybe you'd like jsonnet: https://jsonnet.org/

I find it particularly useful for configurations that often have repeated boilerplate, like ansible playbooks or deploying a bunch of "similar-but" services to kubernetes (with https://tanka.dev).

Dhall is also quite interesting, with some tradeoffs: https://dhall-lang.org/

A few years ago I did a small comparison by re-implementing one of my simpler ansible playbooks: https://github.com/retzkek/ansible-dhall-jsonnet

- validation is often impractical (at least identifying exactly where the error is… I’m looking at you Helm!)

Unrelated to OP, but you can leverage Tanka to extend helm charts with functionality not provided by upstream.

Although jsonette might be considered more complex Tanka is a great alternative for k8s config management.

At Grafana Labs we're using jsonnet at scale, while being a powerful functional language it is also excellent for rendering JSON/YAML config. We have developed Tanka[0] to work with Kubernetes, for other purposes I can recommend this course[1] (authored by me).

If you're hitting the limits of Kustomize, maybe look at Tanka as well.

Yes, try Tanka.

yes. basically. and this is a path that multiple people are trying to solve. e.g. AWS CDK8s, https://tanka.dev/, etc

Compose would be awesome.

(Note I work for Grafana Labs who fund Tanka and use it for all production config)
