kubernetes - 无法获取我的 kubernetes 主节点的 externalID(即由 aws 提供的 instanceId)

Question

我确实尝试过 kubectl 描述节点 masterNodeName ，它给出的输出为:-

Name:               ip-172-28-3-142
    Roles:              master
    Labels:             beta.kubernetes.io/arch=amd64
                        beta.kubernetes.io/os=linux
                        kubernetes.io/arch=amd64
                        kubernetes.io/hostname=ip-172-28-3-142

编辑: - 我正在使用 kubeadm 在 aws EC2 实例上设置 Kubernetes。

我正在寻找一种在节点配置中获取 InstanceID 作为 externalID 的方法。

我的 V1Node 类集群信息也是空的

ExternalID是 deprecated从 1.1.

不幸的是你不能在 1.11 的版本中获得它，当时它是 finally cleaned .

唯一的方法是回滚/向后移植更改并构建您自己的版本。
