kubernetes nginx服务无法从浏览器打开

Question

我在ubuntu 20.4的minikube上运行nginx pod和Loadbalancer服务。但是，我无法从浏览器打开nginx默认主页。我无法从输出端点的Yaml文件中找到任何问题。我还需要做些什么来从浏览器命中我的Nginx pod吗?

Yaml文件:

apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 1
selector:
matchLabels:
app: nginx

您正在使用非默认端口(8080)来监听nginx容器。您应该将其更改为nginx默认侦听的端口80。或者你可以改变(为什么? !)的端口nginx听这里描述。
