我尝试设置一个 docker-compose 环境，其中 Nginx 容器接收 HTTPS 请求、处理 SSL 并将它们反向代理到仅实现 HTTP 的 dotnet-core 应用程序。

这个主题已经在这里讨论过几次了，我试图创建一个仅用于此目的的最小配置（类似于此：NGINX SSL 直通和 Docker）

问题是，尽管配置为将请求 proxy_pass 到 dotnet-core 应用程序，Nginx 仍会响应 404，而该应用程序当前仅对所有请求响应“Hello world”。

我连接到容器并从那里提取设置

没有 nginx 应提供的条目/etc/nginx/html/index.html。我遗漏了什么？

答案1

您设置了两个重复的虚拟主机，一个在certbot.conf，另一个在default.conf。两个虚拟主机都在端口 80 和 上运行server_name localhost。因此 nginx 会忽略另一个并始终使用第一个。

要解决此问题，请删除certbot.conf并使用以下内容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;
    }
}
