标签： docker kubernetes kubectl rancher rke

我有以下配置来启动rke。当我上rke时。我得到了错误。

rancher-cluster.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

当我上rke时，出现以下错误

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。

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都相同。此设置用于设置节点在节点到节点连接上应使用的IP地址。 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
