Rancher 2.0 简单使用 重要部分截取

学习地址 ： https://rancher.com/docs/rancher/v2.x/en/quick-start-guide/

Install Rancher

　　　　　　docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher

Create The Cluster

　　　　　　

　　　　　　

　　　　　　第 9和10步会有坑：

　　　　　　　　粘贴复制的如果是这样的

docker run -d --privileged --restart=unless-stopped --net=host -v /etc/kubernetes:/etc/kubernetes -v /var/run:/var/run rancher/rancher-agent:v2.0.0 --server https://111.231.54.107 --token 6vjzssptlf2scfnl4vtfn58xhc6p62s6tbrfv9ct8j2vqt2fm4drpz --ca-checksum f4d5d930d3b0265e5cac3ad8380dafe5513179e53f55d5950c1eef2559eaa91d --etcd --controlplane --worker

　　　　　　　　那添加多个节点会出问题 由于 下图显示的 requestedHostname 很可能会冲突 默认貌似是 node ip地址的前三位

　　　　　　　　　　解决方法：必须添加一个参数 直接接在 docker run -d 后面 --hostname=xxx 添加在最后面没用

　　　　　　　　　　下图黄色的这个容器在 node 成功添加到集群后会消失
