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
