3.10 openshift-ansible install is failing - cni not configured



I am attempting to use the openshift-ansible installer for 3.10 to deploy openshift on 1 master and 3 minions. I am using the same inventory I have been using for 3.9 with the changes shown below. I'm consistently hitting a problem with the control plane pods not appearing. Looking in to it, it seems that the cni plugin is not being configured properly. From systemctl status origin-node, I see the following:

E0911 06:19:25.821170   18922 kubelet.go:2143] Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

Is there something I need to add to my 3.10 inventory to address this? Are there other workarounds?
