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

Question

我在两台机器上安装了microk8s(1.24/stable)。\n两台机器的ip分别是\xef\xbc\x9a172.29.99.187、172.29.99.188。\n我在172.29.99.187\xef\xbc\下操作命令x9amicrok8s add-node

\n

输出：

\n

From the node you wish to join to this cluster, run the following:\nmicrok8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\n\nUse the '--worker' flag to join a node as a worker not running the control plane, eg:\nmicrok8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916 --worker\n\nIf the node you are adding is not reachable through the default interface you can use one of the following:\nmicrok8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\nmicrok8s join 192.168.192.122:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\nmicrok8s join 172.24.0.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\nmicrok8s join 172.30.239.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\nmicrok8s join 172.17.0.1:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\n

我在172.29.99.188\xef\xbc\x9a处操作命令

\n

microk8s join 172.29.99.187:25000/57a191d07ce8fe360e13f4f1e9026ce8/5be428d4e916\n

输出：

\n

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