我有以下配置来启动 rke。当我起来的时候rke。我得到了错误。

牧场主集群.yml

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

当我启动时rke，我收到以下错误

FATA[0059] [network] Can't access KubeAPI port [6443] on Control Plane host: 192.168.88.245

在 192.168.88.24（节点）中，kube-apiserver已经在运行。

在此处输入图像描述

我已经打开了端口

firewall-cmd --zone=public --add-port=6443/tcp --permanent
firewall-cmd --reload

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

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
