kubeadm init --apiserver-advertise-address 标志在配置文件中等效

Question

我需要使用 kubeadm 配置文件初始化我的 kubernetes 集群，因为我需要传递一些额外的参数，这些参数不能直接用于kubeadm init.

我确实创建了一个配置文件，它工作正常。我浏览了 kubeadm 配置文件的文档，但仍然无法获得与命令行标志等效的选项--apiserver-advertise-address

我的 kubeadm 版本是 1.15.7

这是我当前的配置：注释掉的行是我已经尝试过但似乎不起作用的选项。

#apiVersion: kubeadm.k8s.io/v1beta2
#kind: InitConfiguration
#APIEndpoint:
#  advertiseAddress: "192.168.224.22"
#  bindPort: 6443
#controlPlaneEndpoint: "192.168.224.22:6443"
apiServer:
  advertiseAddress: "192.168.224.22"
  extraArgs:
    authorization-mode: Node,RBAC
#    advertise-address: 192.168.224.22
    authentication-token-webhook-config-file: /webhook/webhook-config.yaml
  extraVolumes:
  - name: "webhook-conf"
    hostPath: "/webhook/"
    mountPath: "/webhook/"
    readOnly: true
    pathType: DirectoryOrCreate
  timeoutForControlPlane: 4m0s
apiVersion: kubeadm.k8s.io/v1beta2
certificatesDir: /etc/kubernetes/pki
clusterName: kubernetes
controllerManager: {}

#APIEndpoint:

#  bindPort: 6443
imageRepository: k8s.gcr.io
kind: ClusterConfiguration
kubernetesVersion: v1.15.10
networking:
#  advertiseAddress: "192.168.224.22"
  dnsDomain: cluster.local
  podSubnet: 10.244.0.0/16
  serviceSubnet: 10.96.0.0/12
scheduler: {}

这就是我正在尝试配置的内容。

要--apiserver-advertise-address在 kubeadm 配置文件中指定标志，请在 init 配置中使用它：

localAPIEndpoint:
  advertiseAddress: 192.168.224.22
  bindPort: 6443

最初，当我使用它时，地址发生了变化，但随后由于 CRI 套接字配置错误，工作节点无法加入集群。

结果 usingkubeadm config view不会打印出集群创建期间使用的整个配置。The kind: InitConfiguration被跳过，因此发生了错误配置。

使用kubeadm config print init-defaults来获取配置文件的初始块。那么它应该工作。

最终工作配置文件：

apiVersion: kubeadm.k8s.io/v1beta2
bootstrapTokens:
- groups:
  - system:bootstrappers:kubeadm:default-node-token
  token: abcdef.0123456789abcdef
  ttl: 24h0m0s
  usages:
  - signing
  - authentication
kind: InitConfiguration

  advertiseAddress: 192.168.224.22
  bindPort: 6443
nodeRegistration:
  criSocket: /var/run/dockershim.sock

  taints:
  - effect: NoSchedule
