支持的工作负载类型

Vegeta Trait 支持下面的几种工作负载webservice，worker 和 cloneset。

开始使用

使用一个 webservice 组件来开始，将下面的声明保存到 show-vegeta.yaml，并运行 vela up -f show-vegeta.yaml 来启动。

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: new-vegeta
  namespace: vegeta
spec:
  components:
    - name: new-vegeta
      type: webservice
      properties:
        exposeType: ClusterIP
        image: nginx:latest
        ports:
        - expose: true
          port: 80
          protocol: TCP
          ports: 80
      traits:
        - type: vegeta
          properties:
            dorequest: 'GET http://show-vegeta:80'
            parallelism: 1
            backofflimit: 10

检查 app 和 trait 的状态：

vela ls app -n vegeta

• 如果你想获取一个更友好的输出，使用下面这两个工具： jaggr 和 jplot 来查看数据。

kubectl logs new-vegeta--1-qrh67  -n vegeta -f | jaggr @count=rps hist\[100,200,300,400,500\]:code p25,p50,p95:latency sum:bytes_in sum:bytes_out | jplot rps+code.hist.100+code.hist.200+code.hist.300+code.hist.400+code.hist.500 latency.p95+latency.p50+latency.p25 bytes_in.sum+bytes_out.sum
