牧场主的RKE无法在新集群上启动

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。我的理解是牧场主/k8s将为我设置这些…什么的。

这是rke无法启动的尾部。

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

根据我的理解，接口配置必须预先存在。RKE将不负责接口配置。

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