V2EX-kubeadm init –config [file.yaml] 后实际配置与 yaml 里的配置不符

OldCarMan:

今天使用 kubeadm reset 后，再使用 kubeadm init 来重新初始化 k8s 时，发现初始化后实际配置跟我 yaml 设定的配置不一样。

具体情况，打个比方：我 yaml 文件里面 criSocket(参考文档)配置的是：

criSocket: unix:///var/run/cri-dockerd.sock

然而实际情况得到的 criSocket 则是：

criSocket: unix:///var/run/containerd/containerd.sock

下面是我 init 初始化日志&yaml 配置&InitConfiguration 实际配置结果：

• 这是调用 kubeadm init 初始化成功输出(没报错)：

[email protected] ~/k8s/]# kubeadm init --config=/root/k8s/kubeadm/config.yaml --upload-certs
[init] Using Kubernetes version: v1.26.0
[preflight] Running pre-flight checks
[WARNING FileExisting-tc]: tc not found in system path
[preflight] Pulling images required for setting up a Kubernetes cluster
[preflight] This might take a minute or two, depending on the speed of your internet connection
[preflight] You can also perform this action in beforehand using 'kubeadm config images pull'

...

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

• 这是我的 yaml 配置文件：

apiVersion: kubeadm.k8s.io/v1beta3
kind: InitConfiguration
nodeRegistration:
  criSocket: unix:///var/run/cri-dockerd.sock
  kubeletExtraArgs:
    runtime-cgroups: /system.slice/docker.service
    pod-infra-container-image: registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.7

---
apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind: KubeProxyConfiguration
mode: ipvs
ipvs:
  minSyncPeriod: 8s
  syncPeriod: 8s
  scheduler: 'wrr'
  
  ....(省略其他配置)

• 这是我运行kubeadm config print init-defaults后 输出的实际配置日志

[[email protected] k8s]# kubeadm config print init-defaults
apiVersion: kubeadm.k8s.io/v1beta3
bootstrapTokens:
- groups:
  - system:bootstrappers:kubeadm:default-node-token
  token: abcdef.0123456789abcdef
  ttl: 24h0m0s
  usages:
  - signing
  - authentication
kind: InitConfiguration
localAPIEndpoint:
  advertiseAddress: 1.2.3.4
  bindPort: 6443
nodeRegistration:
  criSocket: unix:///var/run/containerd/containerd.sock
  imagePullPolicy: IfNotPresent
  name: node
  taints: null
---

.....(省略其他配置)

• 大佬们觉得是什么问题，另外大家平时是怎么部署 k8s 集群的，谢谢大家回复。
