交付dubbo-monitor监控服务到k8s

1.下载软件包

首先下载 dubbo-monitor源码包 7-200

dubbo-monitor是监控zookeeper状态的一个服务，另外还有dubbo-admin，效果一样，感兴趣的可以自己研究一下。

[root@hdss7-200 src]# # yum -y install unzip

[root@hdss7-200 src]# #unzip dubbo-monitor

[root@hdss7-200 src]# # mv dubbo-monitor-mster dubbo-monitor

[root@hdss7-200 src]# cd /opt/src/dubbo-monitor

 

[root@hdss7-200 dubbo-monitor]# vi /opt/src/dubbo-monitor/dubbo-monitor-simple/conf/dubbo_origin.properties

优化修改Dockerfile并限制jvm资源，将最后的exec命令的后台&符号删除，并且将exec命令下面的都干掉：

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

执行docker build并上传镜像到我们的私有仓库：

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

 

 

 

 

2 制作资源配置清单：

1、dp.yaml

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

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

vi dp.yaml

    rollingUpdate:

svc

kind: Service
apiVersion: v1
metadata: 
  name: dubbo-monitor
  namespace: infra
spec:
  ports:
  - protocol: TCP
    port: 8080
    targetPort: 8080
  selector: 
    app: dubbo-monitor

ingress

kind: Ingress
apiVersion: extensions/v1beta1
metadata: 
  name: dubbo-monitor
  namespace: infra
spec:
  rules:
  - host: dubbo-monitor.od.com
    http:
      paths:
      - path: /
        backend: 
          serviceName: dubbo-monitor
          servicePort: 8080

3应用资源配置清单：node节点

# 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

验证：

# kubectl get pod -n infra
