Rancher INGRESS

Rancher ingress控制器利用Rancher中现有的负载均衡功能，将Kubernetes ingress的内容转换到Rancher的负载均衡器。

ingress controller 功能:

监听Kubernetes服务器事件;
部署负载平衡器，并将其与Ingress中定义的路由规则进行适配;
通过配置Ingress Address 字段来做为负载均衡器的公共接入地址。

设置一个NGINX服务示例
在配置任何ingress之前, 需要在Kubernetes中创建服务. 首先在Kubernetes环境中添加一个服务和复制控制器（Replication Controller）。

这里添加单个的nginx服务到Kubernetes中。

编写main.lua ，用于启动并使用该插件，此处我用的是lua-resty-kafka插件

编写Dockerfile，调整镜像将插件导入其中
