I think the GP may have meant, not using configurations of tools that are off the beaten path. Jsonnet as a templating language works very well with k8s yamls.

I think the GP may have meant, not using configurations of tools that are off the beaten path. Jsonnet as a templating language works very well with k8s yamls. Pulumi is also phenomenal at having infrastructure as code versioned in repo. Pulumi and Typescript work very well for type checked templates. K8s yamls also officially have TS types so that works pretty well too.
