创建 MicroK8s 集群时出错：连接失败。加入节点的主机名 (xx) 无法解析为 IP“xx”。拒绝加入 (400)

我在两台机器上安装了microk8s(1.24/stable)，两台机器的ip分别是：172.29.99.187，172.29.99.188，我在172.29.99.187上操作命令：microk8s add-node

输出：

From the node you wish to join to this cluster, run the following:
microk8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916

Use the '--worker' flag to join a node as a worker not running the control plane, eg:
microk8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916 --worker

If the node you are adding is not reachable through the default interface you can use one of the following:
microk8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916
microk8s join 192.168.192.122:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916
microk8s join 172.24.0.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916
microk8s join 172.30.239.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916
microk8s join 172.17.0.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916

我在172.29.99.188操作命令：

microk8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916

输出：

Contacting cluster at 172.29.99.187
Connection failed. The hostname (cxsw) of the joining node does not resolve to the IP "172.29.99.188". Refusing join (400).

我在github上找到了解决方案：https://github.com/canonical/microk8s/issues/2967#issuecomment-1059942384

在172.29.99.188机器上编辑/etc/hosts，添加：

172.29.99.188 cxsw
