浏览器上的Nginx Ingress 404

Question

为托管在nginx docker容器中的react应用程序创建了一个Ingress。

入口配置

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: my-ingress
labels:
helm.sh/chart: home-service
app.kubernetes.io/name: home-service
app.kubernetes.io/instance: xrayed-vulture
app.kubernetes.io/version: "1.0.0"
app.kubernetes.io/managed-by: Tiller
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- host: "home-service.net"
http:
paths:
- path: "/pmr"
backend:
serviceName: my-service
servicePort: 8089

服务

apiVersion: v1
kind: Service
metadata:
name: my-service
labels:
helm.sh/chart: home-service
app.kubernetes.io/name: home-service
app.kubernetes.io/instance: xrayed-vulture
app.kubernetes.io/version: "1.0.0"
app.kubernetes.io/managed-by: Tiller
spec:
type: ClusterIP
ports:
- port: 8089
targetPort: 8089
protocol: TCP
name: http
- port: 443
targetPort: https
protocol: TCP
name: https
selector:
app.kubernetes.io/name: pmr-ui-app

我的react应用程序中的Nginx/etc/nginx/conf.d/default.conf配置，它托管在Nginx:稳定的高山容器中。

server {
listen 8089;
listen 443 default ssl;
server_name localhost;
root   /usr/share/nginx/html;
ssl_certificate /etc/nginx/certs/nginx.crt;
ssl_certificate_key /etc/nginx/certs/nginx.key;
ssl_protocols        SSLv3 TLSv1;
ssl_ciphers          HIGH:!aNULL:!MD5;
location / {
root   /usr/share/nginx/html;
index  index.html index.htm;
try_files $uri /index.html;
}
error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   /usr/share/nginx/html;
}
access_log /var/log/nginx/access.log main;
error_log   /var/log/nginx/error.log  warn;
}

对blow地址进行卷曲调用，入口工作正常并返回右侧页面

curl -v http://home-service.net/pmr

message from my nginx controller container

但是访问浏览器时，我看到404加载了一些.js和css文件

带http://home-service.net/pmr的Chrome

React Nginx container will recieve the request with 200 like this
10.x.x.25 - - [02/Sep/2020:14:25:27 +0000] "GET / HTTP/1.1" 200 3009 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36" "10.210.62.200"

为什么请求不是全部由my-service单独处理，而是由upstream-default-backend处理css和.js文件，从而导致404？

Nginx入口控制器版本：nginx-ingress-controller:0.26.1

您的资源使用根路径/static呈现。这是一个单独的HTTP请求，将获得默认的后端，因为它不满足/pmr路径规则。您应该在web应用程序中使用相对路径，以便反向代理正常工作。例如，去掉/根，只使用static/css/main.css。或者使用主机名规则而不是路径规则。
