I see a problem here. I'm not certain if the sort of person who would choose YAML as their configuration language sees a problem here. There is a direct conflict between human-centred data representations and computer-centred. Computers love things that look like a bit like a Lisp. Humans like things that look a bit like Python. If you're the sort of person who wants to use a computer to manipulate their Kubernetes config then you'd be secretly annoyed that Kubernetes uses YAML. However, it appears the Kubernetes community are mainly YAML people, so why would they mind that their config files will be horrible to work with once programming logic gets involved? The downside of YAML is exactly this scenario, and I believe the people involved in K8s are generally cluey enough to see that coming. > YAML is a superset of JSON The spec writers can put whatever they want in their document, but I don't think this is true. If you go in and convert all the YAML config to JSON, the DevOps team is going to get upset. The two data formats have the same semantic representation, but so do all languages compiled to the same CPU arch. JSON and YAML are disjoint in practice. Mixing the two isn't a good idea.
