rancher导入kubenetes报错：websocket: bad handshake

昨天因为需求，所以需要部署新的环境，然后就创建了kubenetes，想着还是使用rancher来管理来着，但是在导入rancher的时候总是报错：websocket: bad handshake，百度了很久，有的说是因为插件的问题，有的说是计算机名的问题，还有的说是rancher的底层问题。但是我前段时间确实使用的同一个版本的rancher和kubenetes做导入是没有任何问题的。都正常了。没办法，只能一个一个的找了，我发现kubenetes中的pod无法和我node节点同一个网段的节点通信，这个就比较出来了，原来pod不是跟所有node节点，只是和rancher这个服务的节点不能通行，其他都正常，而且rancher客户端的日志出现内容如下：

我尝试着在pod里去ping一下rancher的节点ip，不能通信，和其他的节点正常，这个问题就比较明显了，rancher这个节点有问题。下面继续分析，在rancher这个服务上的docker的ip地址和node节点的ip地址是一个网段的，有冲突了。修改一下docker的节点ip端。

vim /etc/docker/daemon.json
{
    "bip":"192.168.0.1/24"
}

我这里docker默认的网断和宿主机是一个网段的，这里做一下修改，然后重启一下docker，在重新试一下问题解决。
