【问题描述】：
我在定义 https://github.com/pablotoledo/kubernetes-poc/blob/master/Vagrantfile 的 Vagrantfile 时遇到问题。
在我设置的这个 Vagrant 文件中：
- 1 大师
- 2 名工人
我已经定义了一些要在每个 VM 上运行的脚本：
- 用于 Master 的 SSH 密钥生成器 -> script_generate_ssh_key
- SSH 复制密钥将 id_rsa 从 master 复制到 worker -> script_copy_key
- 在每个 VM 上安装通用软件的脚本 -> script_install_common_software 此脚本基于 https://kubernetes.io/docs/setup/independent/install-kubeadm/
- 另一个设置主节点角色的脚本 -> script_setup_master
- 最后一个脚本用于将worker加入master -> script_setup_worker
当我运行“vagrant up”时，命令“sudo kubeadm init --pod-network-cidr=192.168.0.0/16 --apiserver-advertise-address=192.168.40.10”总是挂起。
如果我 ssh 到主节点，我可以看到 kube-apiserver 容器总是在大约 3 分钟后重新创建。
这是一个崩溃的 kube-apiserver 实例的输出：
Flag --insecure-port has been deprecated, This flag will be removed in a future version.
Flag --admission-control has been deprecated, Use --enable-admission-plugins or --disable-admission-plugins instead. Will be removed in a future version.
