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)：
root@master1 ~/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

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

- 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。
