交付Dubbo-monitor监控到k8s

准备docker镜像

在运维主机10.10.10.200上执行

下载镜像

# cd /opt/src
# wget https://github.com/Jeromefromcn/dubbo-monitor/archive/master.zip

解压、修改配置

# unzip master.zip
# vim /opt/src/dubbo-monitor/dubbo-monitor-simple/conf/dubbo_origin.properties
修改以下对应参数
dubbo.registry.address=zookeeper://zk1.od.com:2181?backup=zk2.od.com:2181,zk3.od.com:2181
dubbo.protocol.port=20880
dubbo.jetty.port=8080
dubbo.jetty.directory=/dubbo-monitor-simple/monitor
dubbo.statistics.directory=/dubbo-monitor-simple/statistics
dubbo.charts.directory=/dubbo-monitor-simple/charts
dubbo.log4j.file=logs/dubbo-monitor.log

优化Docker镜像

# sed -r -i -e '/^nohup/{p;:a;N;$!ba;d}'  ./dubbo-monitor-simple/bin/start.sh && sed  -r -i -e "s%^nohup(.*)%exec \1%"  ./dubbo-monitor-simple/bin/start.sh

制作镜像

# cp -a dubbo-monitor/ /data/dockerfile/
# cd /data/dockerfile/dubbo-monitor
# docker build . -t harbor.od.com/infra/dubbo-monitor:latest
# docker push harbor.od.com/infra/dubbo-monitor:latest

准备资源配置清单

在运维主机10.10.10.200上执行

# mkdir /data/k8s-yaml/dubbo-monitor
# cd /data/k8s-yaml/dubbo-monitor

应用资源清单

在任意计算节点执行

# kubectl apply -f http://k8s-yaml.od.com/dubbo-monitor/dp.yaml
# kubectl apply -f http://k8s-yaml.od.com/dubbo-monitor/svc.yaml
# kubectl apply -f http://k8s-yaml.od.com/dubbo-monitor/ingress.yaml

配置域名解析

此步骤在DNS服务器上操作

增加一条dubbo-monitor的A记录解析到VIP：10.10.10.25

测试解析

# dig -t A dubbo-monitor.od.com @10.10.10.20 +short
