liveness和readiness对比及区别

          livenessProbe:
            httpGet:
              path: /appHealth
              port: 5003
              scheme: HTTP
              httpHeaders:
                - name: User-Agent
                  value: Pod Health Check
                - name: Content-Type
                  value: application/json;charset=UTF-8
            initialDelaySeconds: 10
            timeoutSeconds: 2
            periodSeconds: 10
            successThreshold: 1
            failureThreshold: 3
          readinessProbe:
            httpGet:
              path: /appHealth
              port: 5003
              scheme: HTTP
              httpHeaders:

            periodSeconds: 10
            successThreshold: 1
            failureThreshold: 3
          startupProbe:
            httpGet:
              path: /appHealth
