       livenessProbe:#livenessProbe是K8S认为该pod是存活的，不存在则需要kill掉，然后再新启动一个，以达到RS指定的个数。
         httpGet:
           path: /
           port: 80
           scheme: HTTP
         initialDelaySeconds: 30
         timeoutSeconds: 5
         successThreshold: 1
         failureThreshold: 5
       readinessProbe:#readinessProbe是K8S认为该pod是启动成功的，这里根据每个应用的特性，自己去判断，可以执行command，也可以进行httpGet。
         httpGet:
           path: /
           port: 80
           scheme: HTTP
         initialDelaySeconds: 30
         timeoutSeconds: 5
         successThreshold: 1
         failureThreshold: 5
