通过 NGINX INGRESS 和文件类型公开 Kubernetes 服务时出错：LoadBalancer

如何解决通过 NGINX INGRESS 和文件类型公开 Kubernetes 服务时出错：LoadBalancer

我有一个使用 Docker 构建的 Vuejs 应用程序，使用 Nginx 分 2 个阶段构建：

# estágio de compilação 

FROM node:10-alpine as build-stage 

workdir /app 

ARG VUE_APP_BASE_URL="minha-base-url" 

ENV VUE_APP_BASE_URL=${VUE_APP_BASE_URL} 

copY package*.json ./ 

RUN npm install 

copY . . 

RUN npm run build 

 
 

# estágio de produção 

FROM Nginx:stable-alpine as production-stage 

copY --from=build-stage /app/dist /usr/share/Nginx/html 

copY --from=build-stage /app/Nginx.conf /etc/Nginx/conf.d/Nginx.conf 

EXPOSE 80 

CMD ["Nginx","-g","daemon off;"] 

 

Nginx.conf：

server {

  listen 80; 

  location / {
    alias /app/dist;
    index index.html index.htm;
    try_files $uri $uri/ @rewrites;
  }
  
  location @rewrites {
   rewrite ^.$ /index.html last;
  }

  error_page   500 502 503 504  /50x.html;

  location = /50x.html {
    root   /usr/share/Nginx/html;
  }
}

通过触发 docker run 命令一切正常。当升级到 kubernetes 时，使用 port-forward 一切正常：

kubectl port-forward deployment/app-front 8082:80 

最大的问题是，当我使用 1-type:LoadBalancer 创建服务时，我无法通过生成的外部 IP 访问应用程序，2- 同样，当我尝试通过 Nginx INGRESS 时，它会给出错误 503。注意：我还有其他在上面提到的这两种情况下完美运行的服务，但这些其他应用程序不是建立在 docker 上的 Nginx 映像之上，所以我怀疑错误可能由于某些冲突来自那里，但我无法得出具体结论。以下是文件：

我已经头昏脑胀好几天了，找不到解决办法，有人可以帮帮我吗？

注意：通过这些相同的配置，我可以公开我拥有的其他服务。
