Dokku Nginx提供静态文件

Question

我正试图在dokku上设置node.js网络应用程序的部署。然而，我的应用程序的根路径只需要提供静态html、css和javascript，所有其他路由"/api/…"都应该发送到我的节点应用程序，该应用程序正在5000端口上运行。我试着用以下nginx.ssl.conf.template:来设置它

http {
    proxy_cache_path  /var/cache/nginx levels=1:2 keys_zone=one:8m max_size=3000m inactive=600m;
    proxy_temp_path /var/tmp;
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    gzip on;
    gzip_comp_level 6;
    gzip_vary on;
    gzip_min_length  1000;
    gzip_proxied any;
    gzip_types text/plain text/html text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_buffers 16 8k;
    upstream ceresshop_api {
      server 127.0.0.1:5000;
      keepalive 64;
}
server {
  listen      [::]:$NGINX_PORT;
  listen      $NGINX_PORT;
  server_name $NOSSL_SERVER_NAME;
  access_log  /var/log/nginx/${APP}-access.log;
  error_log   /var/log/nginx/${APP}-error.log;
  return 301 https://$host:$NGINX_SSL_PORT$request_uri;
}
server {
  listen      [::]:$NGINX_SSL_PORT ssl spdy;
  listen      $NGINX_SSL_PORT ssl spdy;
  server_name $SSL_SERVER_NAME;
  access_log  /var/log/nginx/${APP}-access.log;
  error_log   /var/log/nginx/${APP}-error.log;
$SSL_DIRECTIVES
  keepalive_timeout   70;
  add_header          Alternate-Protocol  $NGINX_SSL_PORT:npn-spdy/2;
  location ~ ^/(images/|img/|javascript/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico) {
         root /data/public;
         access_log off;
         expires max;
       }
  location    / {
    gzip on;
    gzip_min_length  1100;
    gzip_buffers  4 32k;
    gzip_types    text/css text/javascript text/xml text/plain text/x-component application/javascript application/x-javascript application/json application/xml  application/rss+xml font/truetype application/x-font-ttf font/opentype application/vnd.ms-fontobject image/svg+xml;
    gzip_vary on;
    gzip_comp_level  6;
    proxy_pass  http://$APP;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header X-Forwarded-Port $server_port;
    proxy_set_header X-Request-Start $msec;
  }
  include $DOKKU_ROOT/$APP/nginx.conf.d/*.conf;
}

然而，我不确定的"根"参数指向哪里

location ~ ^/(images/|img/|javascripts/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico|index.html) {
         root /data/public;
         access_log off;
         expires max;
       }

因为该应用程序是与dokku一起部署的。就上下文而言，我试图用ngix静态服务的文件位于我的应用程序目录的"public"director中。

nginx配置在容器的外部，因此无法访问容器内部的静态文件。

如果您愿意，您可以将这些文件移动到容器中的已装入卷，然后将nginx指向该已装入卷。否则，你的应用程序将需要以节点应用程序通常的方式为它们提供服务。
