Ubuntu can'；t加入kubernetes群；拒绝连接

尝试加入群集时，我遇到以下错误：

[preflight] running pre-flight checks
    [WARNING RequiredIPVSKernelModulesAvailable]: the IPVS proxier will not be used, because the following required kernel modules are not loaded: [ip_vs_rr ip_vs_wrr ip_vs_sh ip_vs] or no builtin kernel ipvs support: map[ip_vs_sh:{} nf_conntrack_ipv4:{} ip_vs:{} ip_vs_rr:{} ip_vs_wrr:{}]
you can solve this problem with following methods:
 1. Run 'modprobe -- ' to load missing kernel modules;
2. Provide the missing builtin kernel ipvs support

我使用此命令初始化主机：

$ sudo kubeadm init --pod-network-cidr=10.244.0.0/16 –-apiserver-advertise-address=192.168.1.180 --kubernetes-version stable-1.11

要在从属节点中运行的Join命令是：

sudo kubeadm join 10.0.2.15:6443 --token 0ux20u.8atg4nwhaup80qpi --discovery-token-ca-cert-hash sha256:6cf4f16530ae7e28fba67ca7419b047e8ff36bb8e8212c9b3164eff8cad021c6

我无法在IP 10.0.2.15上ping主节点

但我可以在IP:192.168.2.180成功ping，该IP在主VM的Vagrantfile中设置为公共网络的静态IP

我试着在流浪者文件中设置私有网络Ip和公共网络的网桥，但都不起作用

在我使用的同一台机器上：

docker版本1.13.1和 k8s版本1.11

有人能帮我吗？

请发布

vagrant文件

您使用了错误的界面。运行

ip addr

而不是

eth0

使用

eth1

。
