Unable to get Angular to work on a local domain

问题

以下是您提供的内容的翻译部分：

我试图在自定义本地域名 blog.dev 上启动 Angular 应用程序。Angular 应用程序在 https://localhost:4200 上正常工作。但是在 blog.dev 域上无法正常工作。

我的 Angular 部署文件如下所示：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: client-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: client

    spec:

          image: pinakinc/client
          ports:
            - containerPort: 4200
---
apiVersion: v1

    - name: client
      protocol: TCP
      port: 80
      targetPort: 4200
      nodePort: 31000

Nginx 配置文件如下所示：

worker_processes 1;

events {
  worker_connections 1024;
}

http {
  server {
    listen 80;
    server_name localhost;

    root /usr/share/nginx/html;
    index index.html index.htm;
    include /etc/nginx/mime.types;

    gzip on;
    gzip_min_length 1000;
    gzip_proxied expired no-cache no-store private auth;
    gzip_types text/plain text/css application/json application/javascript 
    application/x-javascript text/xml application/xml application/xml+rss 
    text/javascript;

    location / {
      try_files $uri $uri/ /index.html;
    }
  }
}

Your application running on port 4200 so the target port should be 4200 in service also.

So traffic flow like service port 80 > target port 4200 > container port 4200

Target point and container port should get matched.

  • name: client
    image: pinakinc/client
    ports:

    • containerPort: 4200

apiVersion: v1
kind: Service
metadata:
name: client-srv
spec:
selector:
app: client
type: LoadBalancer
ports:
- name: client
protocol: TCP
port: 80
targetPort: 4200
nodePort: 31000

我已经成功解决了问题。解决问题所采取的措施如下：

  1. 更改了nginx配置文件如下：
worker_processes  1;

events {
  worker_connections  1024;
}

http {
  server {
    listen 80;
    server_name  localhost;

    root   /usr/share/nginx/html;
    index  index.html index.htm;
    include /etc/nginx/mime.types;

    gzip on;
    gzip_min_length 1000;
    gzip_proxied expired no-cache no-store private auth;
    gzip_types text/plain text/css application/json 
    application/javascript 
    application/x-javascript text/xml application/xml 
    application/xml+rss 
    text/javascript;

    location / {
      try_files $uri $uri/ /index.html;
    }
  }
}

部署文件如下：

apiVersion: apps/v1
kind: Deployment
metadata: 
  name: client-depl
spec: 
  replicas: 1
  selector: 
    matchLabels:
      app: client
  template: 
    metadata:
      labels:
        app: client 
    spec:
      containers:
        - name: client
          image: pinakinc/client
          ports:
            - containerPort: 4200
---
apiVersion: v1
kind: Service
metadata:
  name: client-srv
spec:
  selector:
    app: client
  type: LoadBalancer
  ports: 
    - name: client
      protocol: TCP
      port: 80
      targetPort: 80
      nodePort: 32000

希望这对你有所帮助。
