使用外部 CA 时，kubeadm 不会创建 controller-manager.conf

使用外部 CA 时，kubeadm 不会创建 controller-manager.conf

我正在尝试使用 kubeadm 初始化 kubernetes 集群，但不幸的是，它没有按预期工作。这是 kubeadm 配置文件：

apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: "v1.19.16"
networking:
  podSubnet: "10.230.0.0/16"
  dnsDomain: "company.internal"
etcd:
  external:
    endpoints:
      - https://kube-etcd-1:2379
      - https://kube-etcd-2:2379
      - https://kube-etcd-3:2379

不幸的是，当我尝试使用以下命令初始化它时，我不断收到此错误kubeadm init --config /root/.config/new-config.yaml：

controller-manager.conf 文件不存在或无效：stat /etc/kubernetes/controller-manager.conf: 没有此文件或目录

kubeadm 自动识别证书已生成并且可以在 /etc/kubernetes/pki 下找到的事实，只有在这种情况下我才会收到此错误。如果我删除证书，它将自行生成所有内容，包括controller-manager.conf。关于如何解决这个问题有什么想法吗？

使用--v = 5除了基本上无法找到controll-manager.conf之外，没有提供任何其他见解：

kube-controlplane-1:/etc/kubernetes/pki# kubeadm init --config /root/.config/new-config.yaml --v=6

欢迎提出任何有关如何调试的想法！

谢谢！

后来编辑：kubeadm 版本：1.19.16

好吧，如果没有 kubeadm 的版本，我们只能猜测，但总体思路是外部 CA 模式（您因ca.crt 存在，但密钥不存在）该方法假设您正在以“已配置”模式部署，因此和controller-manager.conf应该scheduler.conf已经存在

简而言之，就是确保你了解目录内容的情况/etc/kubernetes，下次发布你正在使用的相关版本
