I was having an issue with k8s-openapi complaining:

None of the v1_* features are enabled on the k8s-openapi crate.

The k8s-openapi crate requires a feature to be enabled to indicate which version of Kubernetes it should support.

If you’re using k8s-openapi in a binary crate, enable the feature corresponding to the minimum version of API server that you want to support. In case your binary crate does not directly depend on k8s-openapi, add a dependency on k8s-openapi and enable the corresponding feature in it.
