转发端口时出现以下错误。有人可以帮忙吗？
mjafary$ sudo kubectl port-forward sa-frontend 88:82
Forwarding from 127.0.0.1:88 -> 82
Forwarding from [::1]:88 -> 82
错误日志：

这是吊舱的描述。我的期望是，当我在浏览器中命中localhost：88时，请求应转发到jafary / sentiment-analysis-frontend容器，并且应加载应用程序页面
mjafary$ kubectl describe pods sa-frontend
Name: sa-frontend
Namespace: default
Node: minikube/192.168.64.2
Start Time: Fri, 14 Dec 2018 00:51:28 …我在本地计算机上使用minikube。使用kubernetes端口转发时出现此错误。有人可以帮忙吗？
