##### 导语：对skywalking不了解，想在k8s里搭建skywalking玩一下。 #####

> 采用默认的h2存储数据，尝鲜用。后续可以换成mysql或者es。以下步骤难免有不严谨或者出错的地方。

mkdir -p /srv/skywalking

用来测试的java项目是在k8s集群外的 所以我oap的11800端口就采用nodeport方式放出去了。如果是集群内的话 svc用如下配置应该就可以了

启动oap和ui

kubectl apply -f ./

查看ui界面

启动jar包测试

java -jar -javaagent:/opt/apache-skywalking-apm-bin-es7/agent/skywalking-agent.jar  -Dskywalking.agent.service_name=test-servicecenter -Dskywalking.collector.backend_service=192.168.1.205:30118      ihaozhuo-servicecenter-6.0.1-SNAPSHOT.jar   --spring.profiles.active=test

再次刷新界面

获取到了代码里使用的数据库信息

服务已经注册上，但是只起了一个jar 具体调用和拓扑相关还没有。等待后续正式投入测试之后查看。
