Question

我正在尝试通过8080端口上的rest api将与后端通信的前端连接，前端在nginx上运行，具有非常基本的配置，该配置可服务根文件夹中的静态内容并通过/ api将请求代理到api

下面是配置和部署。

1 /后端部署和服务Yaml文件

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: wetrust-backend
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: wetrust-backend
        tier: backend
        track: stable
    spec:
      securityContext:
        runAsUser: 1000
        fsGroup: 1000
      containers:
        - name: backend
          image: "leean/wetrust-backend"
          imagePullPolicy: Always
          ports:
            - containerPort: 8080
          volumeMounts:
            - name: nfs-volume
              mountPath: /home/uploadDir # Please change the destination you like the share to be mounted too
      volumes:
        - name: nfs-volume
          nfs:
            server: 192.168.99.98 # Please change this to your NFS server
            path: /home/uploadDir # Please change this to the relevant share
---
apiVersion: v1
kind: Service
metadata:
  name: wetrust-backend
spec:
  ports:
    - port: 8080
      targetPort: 8080
  selector:
    app: wetrust-backend
    tier: backend

2 /前端部署和服务yaml文件

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: wetrust-frontend
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: wetrust-frontend
        tier: frontend
        track: stable
    spec:
      containers:
        - name: nginx
          image: "leean/wetrust-frontend"
          imagePullPolicy: Always
          ports:
          - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: wetrust-frontend
spec:
  ports:
    - port: 8889
      targetPort: 80
  selector:
    app: wetrust-frontend
    tier: frontend
  type: NodePort

3 /在要生成图像的静态工件的dist文件夹中的nginx配置

upstream wetrust-backend {
  server wetrust-backend:8080;
}

server {
  listen 80;
  charset uft-8
  gzip on;
  gzip_vary on;
  gzip_min_length 10240;
  gzip_proxied expired no-cache no-store private auth;
  gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml;
  gzip_disable "MSIE [1-6]\.";

  #location / {
   # proxy_pass http://backend;
  #}
  location / {
    root   /usr/share/nginx/html;
    index  index.html;
    expires -1;
    add_header Pragma "no-cache";
    add_header Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
    try_files $uri$args $uri$args/ $uri $uri/ /index.html =404;
  }

  location /api/ {
    proxy_pass http://wetrust-backend;
  }

}

我现在正在努力使nginx代理通过配置使前端与后端通信，但这无济于事

在部署所有yaml文件而没有任何问题之后，我可以通过服务端口（如192.168.x.x：30812）上的nodeport访问frontedn

用户界面正常，但无法在后端端口8080（springboot应用）上连接api

下面是托管前端Pod上的Nginx日志

感谢您的帮助，在此问题上花了我太多时间谢谢
