Information

Docker for Mac: (Edge) 18.03.0-ce-mac58 (23607)
OS X: 10.13.4

 ➜  kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T10:09:24Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.2", GitCommit:"5fa2db2bd46ac79e5e00a4e6ed24191080aa463b", GitTreeState:"clean", BuildDate:"2018-01-18T09:42:01Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}

I had noticed that the docker-for-mac kubernetes implementation does have some flags set for kubernetes Initializers eg: --admission-control=Initializers However there is still an additional flag that needs to be set for the kube-apiserver like so --feature-gates="Initializers=true" and --runtime-config=admissionregistration.k8s.io/v1alpha1.

Steps to reproduce the behavior

Create a basic kubernetes initializerConfiguration manifest.

apiVersion: admissionregistration.k8s.io/v1alpha1
kind: InitializerConfiguration
metadata:
name: config
initializers:
- name: config.initializer.kubernetes.io
rules:
  - apiGroups:
      - "*"
    apiVersions:
      - "*"
    resources:
      - deployments

Create the resource in kubernetes kubectl create -f <initializer-manifest-name> Its at this point the error will occur.

➜  kubectl create -f kubeconfig-initializer.yaml
error: unable to recognize "kubeconfig-initializer.yaml": no matches for admissionregistration.k8s.io/, Kind=InitializerConfiguration

The feature here will be to allow people to edit the kubeadm.yaml used to deploy the cluster. This is in the roadmap and I wish we can work on it soon.
