链路追踪

平台采用SkyWalking作为链路追踪服务，对代码无侵入，仅在部署时简单配置即可使用。

部署调整

需调整Deployment.yaml

• 增加环境变量SW_AGENT_NAME，值为环境::服务名
• 增加环境变量配置字典引用pai-env-skywalking
• 增加存储挂载skywalking-agent

配置摘要：

spec:
  template:
    spec:
      containers:
        - name: pai-demo
          env:
            - name: SW_AGENT_NAME
              value: 'pai::pai-demo'
          envFrom:
            - configMapRef:
                name: pai-env-skywalking
          volumeMounts:
            - mountPath: /opt/skywalking-agent
              name: skywalking
      volumes:
        - hostPath:
            path: /opt/skywalking-agent
            type: ''
          name: skywalking

TODO:
将调整部署命令，在Deployment.yaml中增加labels:skywalking: true即可
