ubuntu - kubernetes nginx 服务未从浏览器打开

Question

我在 ubuntu 20.4 的 minikube 中运行 nginx pod 和 Loadbalancer 服务。但是，我无法从浏览器打开 nginx 默认主页。我从输出端点的 Yaml 文件中找不到任何问题。我是否需要做任何其他事情才能从浏览器中访问我的 Nginx pod？
Yaml 文件:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 8080

apiVersion: v1
kind: Service
metadata:
  name: nginx-service  
spec:

    app: nginx

  ports:
    - protocol: TCP
      port: 8081
      nodePort: 30001
      targetPort: 8080

Answer 1

您正在使用非默认端口(8080)来监听 nginx 容器。您应该将其更改为端口 80 nginx 默认监听的地方。或者，您可以更改(为什么？!)nginx 监听的端口，如 here 所述。 .
