kubeadm初始化报错如下：
[root@ECS-k8s-master docker]# kubeadm init --apiserver-advertise-address=192.168.2.2 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.24.2 --service-cidr=10.140.0.0/16 --pod-network-cidr=10.240.0.0/16

网上查询光说让删除
rm /etc/containerd/config.toml
但其实，删除完后要重启 containerd 服务，不然不生效
完整如下：
rm /etc/containerd/config.toml
systemctl restart containerd
然后再执行
kubeadm init --apiserver-advertise-address=192.168.2.2 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.24.2 --service-cidr=10.140.0.0/16 --pod-network-cidr=10.240.0.0/16
起码这个错误不会出现了，其他错误看之前配置了。
