<p>I'm new to K8s. In process to config Openstack Cinder as K8s StorageClass, i have to add some flags to my kube controller manager, and I found that it's my big problem.
I'm using K8s 1.11 in VMs, and my K8s cluster has a kube-controller-manager pod, but I don't know how to add these flags to my kube-controller-manager. 
After hours search, i found that there's a lot of task require add flag to kube-controller-manager, but no exactly document guide me how to do that. Please share me the way to go over it. </p>

<p>Thank you.</p>

<p>You can check <code>/etc/kubernetes/manifests</code> dir on your master nodes.
This dir would contain yaml files for master components. </p>

<p>These are also known as static pods. </p>

<p>More Info : <a href="https://kubernetes.io/docs/tasks/administer-cluster/static-pod/" rel="noreferrer">https://kubernetes.io/docs/tasks/administer-cluster/static-pod/</a></p>

<p>Update these files and you would be able to see your changes as kubelet should restart the pod on file change.</p>

<p>As a more long term solution, you will need to incorporate the flags to the tooling that you use to generate your k8s cluster.</p>
