K8s初始化超时

k8s初始化超时，如下

百度了一下超时的原因，看来看去就一个“血泪史：k8s Initial timeout of 40s passed.”按照博主的方法去修改如下配置文件
注：kubelet版本按照自己的版本来就行

cd /etc/systemd/system/kubelet.service.d
sudo vim 10-kubeadm.conf 

# Note: This dropin only works with kubeadm and kubelet v1.11+
[Service]
Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf"
Environment="KUBELET_CONFIG_ARGS=--config=/var/lib/kubelet/config.yaml"
# This is a file that "kubeadm init" and "kubeadm join" generates at runtime, populating the KUBELET_KUBEADM_ARGS variable dynamically
EnvironmentFile=-/var/lib/kubelet/kubeadm-flags.env
# This is a file that the user can use for overrides of the kubelet args as a last resort. Preferably, the user should use
# the .NodeRegistration.KubeletExtraArgs object in the configuration files instead. KUBELET_EXTRA_ARGS should be sourced from this file.
EnvironmentFile=-/etc/default/kubelet
ExecStart=
ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS

但是这个配置文件的内容我都存在，不需要修改。
并且我发现一旦初始化超时失败之后，虚拟机变得异常卡顿，怀疑是虚拟机配置问题，于是调高了虚拟机的内存和处理器核数

初始化成功！虽然解决了问题，但是感觉有点尴尬。。。
