Not creating interface for OVS to use #10

Closed edsealing closed 6 years ago

edsealing commented 6 years ago

Kubernetes version: 1.8.3 OVS Version: 2.8.1

I have multus working with OVS-CNI as outlined in the README.

When I create a new Pod, I can see it attempt to create the associated bridge/port, but OVS is throwing the error:

Output from ovs-vsctl show

Port "vethf18e312f"
            Interface "vethf18e312f"
                error: "could not open network device vethf18e312f (No such device)"

@edsealing Hi, we've fixed this issue in the branch johnlin/del-ovs-port

If you want to extend the multiple network interfaces with kubernetes please see the instructions here https://github.com/John-Lin/ovs-cni/tree/johnlin/del-ovs-port/deployments/kubernetes#extend-the-multiple-network-interfaces-with-ovs-cni

Thanks. It looks like my problem was incorrect syntax in the Network resources.

Does the ovs plugin currently support assigning vlan tags to the port at instantiation?
