I'll add my use case: we use hosted kubernetes to deploy all of our branches of all of our projects as fully functional application _stacks_, extremely similarly to how they will eventually run in production. Want to try something and show it to someone in the product owner level? Ok there will be a kube nginx-ingress backed environment up in build-time + a few minutes.

The environments advertise themselves via that same modified ingress's default backend. We stick a tiny bit of deploy yaml in our projects, the deployments kube tagging gives us all the details we need to provide diffs, last build time, links to git repos, web sites etc for the particular environment. The yaml demonstrates conclusively how an app could or should be run, regardless of os or software choice, so when we hand it to ops folks there is a basis for them to run from.
