k8s 搭建 skywalking

k8s 搭建 skywalking

仅用于测试环境es没做持久化,正式环境最好还是把es数据做一下持久化。

agent服务配置

下载agent

这里选择的是8.1.0版本须要对应

https://mirrors.tuna.tsinghua.edu.cn/apache/skywalking/8.1.0/apache-skywalking-apm-8.1.0.tar.gz

可以使用pvc方式或hostpath方式把agent目录挂载到容器内。

服务配置

启动项目jar前加上javaagent文件地址。

- command:
    - java
    - -javaagent:/data/agent/skywalking-agent.jar # 这里的路径可以是相对路径
    - -jar
    - demo.jar

注入环境变量加入skywalking信息

    env:
    - name: SW_AGENT_COLLECTOR_BACKEND_SERVICES
      value: skywalking-oap-server.skywalking:11800 # 指定sw访问地址:端口
    - name: SW_AGENT_NAME
      value: demo # 指定注册上后服务名字

服务端

创建namespaces

kubectl create namespace skywalking
