<p>I have the following conf</p>

<pre><code>cat kubeadm-conf.yaml 

apiVersion: kubeadm.k8s.io/v1beta1
kind: InitConfiguration
apiServerExtraArgs:
  enable-admission-plugins: NodeRestriction,MutatingAdmissionWebhook,ValidatingAdmissionWebhook
networking:
  podSubnet: 192.168.0.0/16
</code></pre>

<p>but, when I do</p>

<pre><code>ps -aux | grep admission
root     20697  7.4  2.8 446916 336660 ?       Ssl  03:49   0:21 kube-apiserver --authorization-mode=Node,RBAC --advertise-address=10.0.2.15 --allow-privileged=true --client-ca-file=/etc/kubernetes/pki/ca.crt --enable-admission-plugins=NodeRestriction

I only see the NodeRestriction
</code></pre>

<p>Please, let me know if anyone can help me make sure that the admission-webhook is indeed running on my cluster.</p>

<p>Thanks for the reply, even that works, posting the kubeadm answer just in case anyone needs it, following is the right kubeadm config:</p>

<pre><code>apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
networking:
  podSubnet: 192.168.0.0/16
apiServer:
  extraArgs:
    enable-admission-plugins: "NodeRestriction,MutatingAdmissionWebhook,ValidatingAdmissionWebhook"
</code></pre>
