我试图在k8s集群中创建一个车集群。
设置- 1个主节点，1个工作节点
这些是我遵循的步骤

Master node: 
sudo kubeadm init --pod-network-cidr=10.244.0.0/16
sudo sysctl net.bridge.bridge-nf-call-iptables=1
sudo sysctl net.bridge.bridge-nf-call-ip6tables=1
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/32a765fd19ba45b387fdc5e3812c41fff47cfd55/Documentation/kube-flannel.yml
kubeadm token create --print-join-command

Worker node: 
kubeadm join {master_ip_address}:6443 --token {token} --discovery-token-ca-cert-hash {hash} --apiserver-advertise-address={worker_private_ip}

Master node - Install rook - (reference - https://rook.github.io/docs/rook/master/ceph-quickstart.html):
kubectl create -f ceph/common.yaml
kubectl create -f ceph/operator.yaml
kubectl create -f ceph/cluster-test.yaml

创建rook-ceph-operator pod时出错：

(combined from similar events): Failed create pod sandbox: rpc error: code = 
Unknown desc = failed to set up sandbox container "4a901f12e5af5340f2cc48a976e10e5c310c01a05a4a47371f766a1a166c304f" 
network for pod "rook-ceph-operator-fdfbcc5c5-jccc9": networkPlugin cni failed to 
set up pod "rook-ceph-operator-fdfbcc5c5-jccc9_rook-ceph" network: failed to set bridge addr: 
"cni0" already has an IP address different from 10.244.1.1/24

有人能帮我解决这个问题吗？
