Ksonnet: Simplify working with Kubernetes configurations

Re: Ksonnet: Simplify working with Kubernetes configurations
#2jsonnet is great. We've been using it at my company to generate our configurations for ElasticBeanstalk, Terraform, and other various auxiliary services.
We've been looking into moving towards Kubernetes. I'm looking forward to seeing if ksonnet can fit our needs.

#3Glad someone put in the effort for this.
I wrote something that fills this econiche sometime last year in Ruby (https://github.com/matsuri-rb/matsuri). Same ideas: mixins, generation of Kubernetes resources, etc. For better or worse, it also adds the idea of combining all the deployment environments into a single workflow and command line interface.
The big difference? Ksonnet is better documented and promoted, lighter-weight, and now better supported within the community.

#5I have been working on a UI based system for managing these configurations in a way that doesn't rely on any particular syntax but allows you to construct object graphs (that is what they all boil down to) directly: http://blog.crudzilla.com/2016/10/managing-configurations-wi...
I will be interested in feedback on how such an approach could be helpful in managing complex configurations.

#6BCL is infamous inside google for being a very powerful footgun; jsonnet is a nice reboot of the idea, with a much saner semantics

can you point to some examples of this matsuri? I failed to figure out what it is from the link you pasted.
A nice thing about jsonnet is that is it's a native data templating language, you don't have to compose a structured data format with a textual template language and deal with things as trailing commas in json or indentation (!!!) in yaml.
It offers a sound model for extending and overriding values.
Another thing: it's a fully featured programming language, but it's purely functional so you are guaranteed that your templates won't have surprising side effects.
In this respect, the most similar alternative is the Nix functional language.

[OP here]
Another goal here is to have something that is easy to embed/repurpose. ruby is pretty heavyweight from that point of view.
While jsonnet is a C program right now (https://github.com/google/jsonnet) we are looking at picking up work on a go port so it is easier to integrate with the kubernetes universe.

Also look at http://ksonnet.io that redirects to the github org for now. We will work on a community page to host there soon.

#10Is there a dockerhub image or linux binary available? Trying to figure out the context of best way to use this in a job. Currently have been using containerized https://github.com/andreasjansson/envtpl in my builds and been pretty happy with it.
