我有以下配置来启动rke。当我打开rke时。我得到了错误。

rancher-cluster.yml

代码语言：javascript
运行
复制
nodes:
  - address: 192.168.88.246
    internal_address: 172.17.0.1
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.243
    internal_address: 172.17.0.1
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.245
    internal_address: 172.17.0.1
    user: dockeruser
    role: [controlplane,worker,etcd]

services:
  etcd:
    snapshot: true
    creation: 6h
    retention: 24h

当我打开rke时，我得到以下错误

问题是internal_address IP都是一样的。此设置用于设置节点应在哪个IP地址上进行节点到节点连接的通信。当您的服务器位于NAT之后时，我们通常会看到此选项。

请尝试以下cluster.yml

代码语言：javascript
运行
复制
nodes:
  - address: 192.168.88.246
    internal_address: 192.168.88.246
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.243
    internal_address: 192.168.88.243
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.245
    internal_address: 192.168.88.245
    user: dockeruser
    role: [controlplane,worker,etcd]

services:
  etcd:
    snapshot: true
    creation: 6h
    retention: 24h
