    如何复现

复现的步骤:

  1. 第一步:编写 inventory.ini 文件,内容如下

    [all]
    192.168.56.11 ansible_port=22 ansible_user="vagrant" ansible_ssh_pass="vagrant"
    ......
  2. 第二步:编写 variables.yaml 文件,内容如下

    skip_verify_node: false
    timezone: Asia/Shanghai
    ......
  3. 第三步:执行部署命令,命令如下

    ansible-playbook -i inventory.ini -e @variables.yaml 90-init-cluster.yml
  4. 出现错误

预期结果

正常完成

屏幕截图

docker info显示使用的cgroup驱动为cgroupfs,导致kubelet使用cgroupfs启动后无法创建容器
修改docker为systemd后,正常完成。
