KubernetesNGINX入口控制器404未找到/未找到物件

我正在 Udemy 學習一門課程，我是Kubernetes世界的新手，我正在嘗試在 Kubernetes 中配置入口 nginx 控制器，但是當我在指定的 URL 發送請求時它回傳404 not found，我已經 10 天了試圖解決它，我看過類似的問題，但他們的答案都沒有對我有用。當我更改檔案中的某些內容時，我還使用Skaffold在docker hub 上自動構建/部署影像。

我的快遞應用服務器：

app.get('/api/users/currentuser', (req, res) => {
  res.send('Hi there');
});

app.listen(3000, () => {
  console.log('[Auth] - Listening on port 3000');
});

Dockerfile：

FROM node:alpine

WORKDIR /app
COPY package.json .
RUN npm install
COPY . . 

CMD ["npm", "start"]

I also executed command from NGINX Ingress Controller docs:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.5/deploy/static/provider/cloud/deploy.yaml

I also changed hosts.file in the system: 127.0.0.1 ticketing.com

Could there be a problem with the Windows IIS web server? since I previously configured something for another project, and in the screenshot above I see:

Requested URL      http://ticketing.com:80/api/users/currentuser
Physical Path      C:\inetpub\wwwroot\api\users\currentuser

Also the screenshot shows the port :80 at the requested URL but I have the server port 3000? when i request at https it returns:

502 Bad Gateway
nginx

also C:\inetpub\wwwroot is strange to me.

Any ideas would help me a lot with continuing the course.

uj5u.com熱心網友回復：

經過幾天的研究，我終于解決了問題，問題出在我在 ASP.NET core 中處理專案時啟用的 IIS Web Server，我將其卸載并解決了問題。

如何從 Windows 10 卸載 IIS：

• 轉到控制面板 > 程式和功能
• 單擊打開或關閉 Windows 功能
• 向下滾動到 Internet 資訊服務
• 單擊 Internet Information Services 旁邊的方塊，使其變為空
• 單擊“確定”并重新啟動 PC（必需）。
