Question

我在如下所示的环境中在WSL2上安装了Ubuntu。当我尝试使用以下所示的步骤将此Ubuntu注册为Kubernetes集群的工作节点时，发生错误。如何注册Ubuntu？

[我的环境]

Windows 10 Pro Insider Preview 1903内部版本18922.1000
- WSL2
WSL2 Ubuntu
- Docker 18.09.5-ce
- kubectl 1.14.3
- kubeadm 1.14.3
- kubelet 1.14.3
主节点
- Ubuntu服务器18.04.2
- Docker 18.09.5-ce
- kubectl 1.14.3
- kubeadm 1.14.3
- kubelet 1.14.3

[我的步骤]

在WSL2上运行Ubuntu
启动Docker服务
```
$ sudo service docker start
```

创建令牌以加入MasterNode上的集群

$ kubeadm token generate
$ kubeadm token create [key] --print-join-command

在Ubuntu上执行以下命令

$ sudo kubeadm join [masterIP]:6443 --token [token] --discovery-token-ca-cert-hash [hash]

如何将现有的Kubernetes集群与在WSL2上运行的Ubuntu相结合？
