Question

/opt/kubernetes/bin/rke up --config /home/msh/rancher-cluster.yml

rancher-cluser.yml 文件包含：

nodes:
  - address: 192.168.10.34
    internal_address: 172.17.0.2
    user: bsh
    role: [controlplane,etcd]
  - address: 192.168.10.35
    internal_address: 172.17.0.3
    user: bsh
    role: [worker]
  - address: 192.168.10.36 
    internal_address: 172.17.0.4
    user: bsh
    role: [worker]
add_job_timeout: 120

注意：我没有在任何节点上配置任何接口 internal_address。我的理解是 rancher/k8s 会为我设置这些。 . .什么的。

这是 rke 无法启动的结尾。

使用：
Rancher v2.5.2
rke v1.0.16 版本
docker-ce-19.03.14-3.el8.x86_64

Answer 1

根据我的理解，接口配置必须预先存在。 RKE 不会负责接口配置。

因此，要么设置一个内部子网并将您的接口分配给它，要么将外部地址也用于内部通信。

rancher 的 rke 无法在新集群上启动
