I want to run pods with runsc as default on my k8s nodes but kube-proxy or other nodes can't be run via runsc. So, I want to automate the process in a way that after the Kubernetes start, every new pod will be run via runsc.
Is there a way to make a RunTimeClass default for a namespace?

To support heterogeneous node configurations, see Scheduling below.
