Hello guys. I use Magnum on Xena and I custom k8s cluster by labels. But My cluster is not ready and there is nothing in /etc/cni/net.d/ and my cluster said: container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: cni plugin not initialized And this is my labels kube_tag=v1.21.8-rancher1,container_runtime=containerd,containerd_version=1.6.10,containerd_tarball_sha256=507f47716d7b932e58aa1dc7e2b3f2b8779ee9a2988aa46ad58e09e2e47063d8,calico_tag=v3.21.2,hyperkube_prefix= docker.io/rancher/ Note: I use Fedora Core OS 31 for images.
