问题分析:

之前我的Docker是用yum安装的,docker的cgroup驱动程序默认设置为systemd。默认情况下Kubernetes cgroup为system,我们需要更改Docker cgroup驱动,

解决方法

# 添加以下内容
vim /etc/docker/daemon.json
{
  "exec-opts": ["native.cgroupdriver=systemd"]
}

# 重启docker
systemctl restart kubelet
# 重新初始化

kubeadm init \
--apiserver-advertise-address=192.168.42.122  \
--image-repository registry.aliyuncs.com/google_containers \
--kubernetes-version v1.22.2 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=all
