我尝试使用dashboard安装Kubernetes，但遇到以下问题：

test@ubuntukubernetes1:~$你知道如何解决这个问题吗？我尝试了以下安装：
Swapoff -a
Remove following line from /etc/fstab
/swap.img none swap sw 0 0
sudo apt update
sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker
sudo apt install apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" >> ~/kubernetes.list
sudo mv ~/kubernetes.list /etc/apt/sources.list.d
sudo apt update
sudo apt install kubeadm kubelet kubectl kubernetes-cni
sudo kubeadm init --pod-network-cidr=192.168.0.0/16
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/master/Documentation/k8s-manifests/kube-flannel-rbac.yml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.0/aio/deploy/recommended.yaml
kubectl proxy --address 192.168.1.133 --accept-hosts '.*'你能给点建议吗？

我今天在一次新的部署中遇到了同样的情况。结果发现，kube-flannel-rbac.yml文件的名称空间错误。它现在是'kube-flannel'，而不是'kube-system'，所以我修改了它并重新应用。
我还在kube-flannel.yml中的每个“name”条目下添加了一个“namespace”条目，roleRef标题下除外。（当我在那里添加它时，它抛出了一个错误）在应用新的yml之后，所有的pod都显示为‘Running‘。

问题似乎出在
kube-flannel-rbac.yaml上它需要
kube-system中的服务帐户所以删掉这个
因为
kube-flannel.yml已经在正确的命名空间中创建了这个。https://github.com/flannel-io/flannel/blob/master/Documentation/kube-flannel.yml#L43

我尝试部署一个3节点集群，其中包含1个主节点和2个工作节点。我采用了类似的方法，如上所述。然后尝试部署Nginx，但失败了。当我检查我的pod时，master上的flannel正在运行，但在worker节点上却失败了。
我删除了法兰绒，从头开始。首先，我只使用了kube-flannel-rbac.yaml，因为有一些提到kube-flannel-rbac.yaml会导致问题。
ubuntu@master：~$ kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml namespace/kube-flannel createdclusterrole.rbac.authorization.k8s.io/flannelclusterrolebinding.rbac.authorization.k8s.io/flannelcreated serviceaccount/flannel created configmap/kube-flannel-cfg created daemonset.apps/kube-flannel-ds created
ubuntu@master：~$ kubectl describe ClusterRoleBinding flannel Name：Labels：注解：角色：种类：ClusterRole名称：法兰绒主题：种类名称命名空间
ServiceAccount flennel kube-flennel
然后我可以创建nginx图像。但是，我随后删除了图像并应用了第二个yaml。这更改了名称空间
ubuntu@master：~$ kubectl describe ClusterRoleBinding flannel Name：Labels：注解：角色：种类：ClusterRole名称：法兰绒主题：种类名称命名空间
ServiceAccount法兰绒kube-system
Nginx再次成功。
此配置的用途是什么？是否需要它，因为部署映像时使用和不使用它？
