网络上的很多信息都告诉我们如何在同一台机器上设置 nginx + fastcgi-mono-server4 以从 linux 环境托管 ASP.net（目前我正在使用带有 Websharper 的 F# 应用程序）。但是 docker 应该只运行一个进程。还有一些解决方案可以使用 runit 或其他工具在同一个容器上运行 nginx 和 mono 服务器。
我让它在同一个容器中工作，但是当我尝试将 Web 应用程序 + fastcgi-mono-server4 移动到另一个容器时，我得到了
[error] 12#12: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.99.1, server: , request: "GET / HTTP/1.1", upstream: "fastcgi://172.17.0.40:32775", host: "192.168.99.100:32786"
找到一篇关于类似要求的文章，但适用于 php fastcgi 服务器（php-fpm），并且仅适用于链接容器。但是对于 fastcgi-mono-server4 它没有。
我尝试使用 fastcgi-mono-server4 + 应用程序文件创建 1 个容器，公开 VOLUME 应用程序文件，公开端口 9000，然后公开 nginx 容器，其中包含来自第一个容器的卷并链接到它还尝试使用 nginx 和 mono 运行 2 个相同的容器安装服务器，首先使用 fastcgi_pass 127.0.0.1:9000，其次使用 fastcgi_pass 172.17.0.40:32775 - 来自第一个容器的 IP 和端口。如果访问第一个容器 - 应用程序工作，访问第二个容器 - 与上述相同的错误。
用于运行单声道服务器的命令：
fastcgi-mono-server4 /printlog=True /applications=/:/var/www/websharper/ /socket=tcp:0.0.0.0:9000 /loglevels=All /verbose=True

在 mono:4.0.0 安装的 docker 镜像之上：
apt-get install -y ca-certificates nginx=1.9.5-1~wheezy
apt-get install -qy mono-fastcgi-server4
apt-get install -qy mono-xsp4
apt-get install -qy fsharp
此外，我确保将 mono 4.5 用于应用程序：
sed -ie 's|mono/4.0|mono/4.5|g' /usr/bin/fastcgi-mono-server4 \
&& sed -ie 's|mono/4.0|mono/4.5|g' /usr/bin/xsp4
还有我的 nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80 default;
access_log /dev/stdout;
error_log /dev/stdout;
root /var/www/websharper;
index main.html;
location / {
root /var/www/websharper/;
fastcgi_pass 172.17.0.40:32775;
include /etc/nginx/fastcgi_params;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
最后是 fastcgi_params
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param HTTPS $https if_not_empty;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param PATH_INFO "";
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
更新：
如果您选择 Any ip，我在来源中发现 TcpSocket 正在分配 Loopback ip……这很奇怪……
class TcpSocket : StandardSocket {
public TcpSocket (System.Net.IPEndPoint localEndPoint)
: base (System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream,
System.Net.Sockets.ProtocolType.IP, localEndPoint)
{
}
public TcpSocket (System.Net.IPAddress address, int port)
: this (new System.Net.IPEndPoint (Equals(address, System.Net.IPAddress.Any) ?
System.Net.IPAddress.Loopback : address, port))
{
}
}
无论如何，我尝试直接为单声道服务器使用设置 IP 地址（通过将 nginx 容器链接到单声道容器）
fastcgi-mono-server4 /printlog=True /applications=/:/var/www/websharper/ /socket=tcp:$(printenv NGINX_HOST_PORT_80_TCP_ADDR):9000 /loglevels=All /verbose=True
并运行盒子
docker run --name t2 --link t1:nginx_host -it -P vasylpurchel/docker-websharper
其中 t1 是一个运行 nginx 的盒子这个测试也失败了：
