我嘗試設置一個 docker-compose 環境，其中 Nginx 容器接收 HTTPS 請求，處理 SSL 並將它們反向代理到僅實現 HTTP 的 dotnet-core 應用程序。

這個話題已經在這裡討論過好幾次了，我試圖創建一個最小的配置來達到這個目的（類似於這個：NGINX SSL Pass-thru and Docker）

問題是，儘管 Nginx 被配置為對 dotnet-core 應用程序的 proxy_pass 請求，但該應用程序仍以 404 響應，該應用程序目前僅對所有請求響應“Hello world”。

nginx_1     | 2021/06/25 04:07:54 [error] 24#24: *1 "/etc/nginx/html/index.html" is not found (2: No such file or directory), client: 210.61.91.199, server: tgdev.pillepalle1.de, request: "GET / HTTP/1.1", host: "tgdev.pillepalle1.de"

我與容器連接並從那裡提取設置

沒有 nginx 應該導致服務的條目/etc/nginx/html/index.html。我錯過了什麼？

您設置了兩個重複的虛擬主機，一個certbot.conf在default.conf. 兩個虛擬主機都在埠 80 和server_name localhost. 因此 nginx 會忽略另一個並始終使用第一個。

要解決此問題，請刪除certbot.conf並使用以下內容default.conf：

server {
   listen       80;
   listen  [::]:80;
   server_name  localhost;

   location /.well-known/ {
       proxy_pass http://certbot;
   }

   location / {
       # return 301 https://$host/$request_uri;
       proxy_pass http://tgwebapp:80;
   }
}
