交付kibana到K8S集群

为什么用kibana：当然运维可以直接在dashboard里exec进去，然后命令行看情况，但是开发或者测试不行，那是机密的，我们得要一个页面供他们使用，使用需要kibana。

# 11机器，解析域名：
~]# vi /var/named/od.com.zone
serial 前滚一位
kibana             A    10.4.7.10
~]# systemctl restart named
~]# dig -t A kibana.od.com @10.4.7.11 +short

# 22机器（21机器还夯着log），应用资源清单：
~]# kubectl apply -f http://k8s-yaml.od.com/kibana/dp.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/kibana/svc.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/kibana/ingress.yaml
~]# kubectl get pods -n infra

我用的低配8C32G，机器快跑不动了，还会显示service not yet

# 200机器：
cd /data/k8s-yaml/prod/dubbo-demo-consumer/
dubbo-demo-consumer]# cp ../../test/dubbo-demo-consumer/dp.yaml .
# y
# 修改namespace为prod，fat改成pro，http地址也改了
dubbo-demo-consumer]# vi dp.yaml
