137. 集群或节点配置卡在节点污染“node.cloudprovider.kubernetes.io/uninitialized”

During the provisioning of RKE2 clusters, the machines are stuck with the status waiting for cluster agent. The rke2-server service is running and pods are being created, but a number of them are in a pending state due to scheduling errors.在配置 RKE2 集群时机器会处于“等待集群代理”状态。rke2 服务器服务正在运行pod 正在创建但由于调度错误其中不少 Pod 处于待处理状态。Example: The vSphere CPI (Cloud Provider Interface) is unable to locate the virtual machine in vSphere, which results in the node being uninitialised. In the downstream cluster, the cloud controller manager pod logs indicate this error locating the virtual machine:示例vSphere CPI云服务提供商接口无法在 vSphere 中定位虚拟机导致节点未初始化。在下游集群中云控制器管理器的 Pod 日志显示了该虚拟机定位的错误search.go:186] Did not find node node1.example.com in vcexample.com and datacenterdatacentre1 nodemanager.go:160] WhichVCandDCByNodeID failed using VM name.

This taint is removed by the CPI once it successfully queries and sets the spec.providerID on the node. If there is a problem with the CPI configuration and this cannot be successfully queried, then the node will remain in this state and fail to complete provisioning. If this is the first node in the cluster then the cluster itself will be stuck in provisioning.node.cloudprovider.kubernetes.io/uninitialized 污染会被添加到配置云服务提供商的集群中新节点。一旦 CPI 成功查询并设置了节点上的 spec.providerID这个污点就会被清除。如果 CPI 配置存在问题且无法成功查询节点将保持该状态无法完成配置。如果这是集群中的第一个节点那么集群本身将被卡在配置中。Additional Information 附加信息Environment 环境A Rancher-provisioned RKE2 cluster with a Cloud Provider configured一个由 Rancher 配置的 RKE2 集群配置了云提供商访问Rancher-K8S解决方案博主企业合作伙伴 https://blog.csdn.net/lidw2009
