k8s.io/kubernetes is not intended to be used with go get

the published staging repos can be used that way (e.g. go get k8s.io/api@<version>)

If you want to depend on k8s.io/kubernetes with go modules, you would need to define require directives for matching levels of all of the published staging repositories in your go.mod file

hi, @liggitt what did you mean by

If you want to depend on k8s.io/kubernetes with go modules, you would need to define require directives for matching levels of all of the published staging repositories in your go.mod file

is it like I import "client-go" using import "k8s.io/kubernetes/staging/src/k8s.io/client-go/kubernetes" instead of import "k8s.io/client-go/kubernetes"?
