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

Deploy a Workload
成功后
Service Discovery 里面会有自动添加的 services 删除 Workloads 里面的 nginx 会自动删除相应的services 而 删除 自动生成的两个services 没用 还会再次自动添加
访问
总共是有两个节点的
访问NGINX的方式
192.168.0.35:31908或192.168.0.36:31908 会自动在10个nginx中负载均衡
最好的测试镜像其实是这个 docker pull lpregistry2018/regularly-used:kubernetes-bootcamp__v1
