From 4.14 to 4.15, the ovnkube-control-plane deployment has scaled back from 3 pods to 2. The networking guide in 4.14 has many references to this pod and shows 3 pods in all the examples. That was correct for 4.14 but it should be 2 in 4.15.  Also, this paragraph needs to be changed:

"The Kubernetes control plane nodes each contain an ovnkube-control-plane pod which does the central IP address management (IPAM) allocation for each node in the cluster. At any given time a single ovnkube-control-plane pod is the leader."

Should say:
"The Kubernetes control plane nodes contain two ovnkube-control-plane pods, on separate nodes, which does the central IP address management (IPAM) allocation for each node in the cluster. At any given time a single ovnkube-control-plane pod is the leader."
