php – Docker和容器之间的连接

我正在尝试在Docker的容器之间建立连接.一个容器有php5-fpm,第二个是nginx.

配置php5-fpm默认,只是几个更改：

listen = 9000

listen.allowed_clients =

和nginx(/ etc / nginx / sites-available / default)：

server {
    listen 80 default_server;
    #listen [::]:80 default_server ipv6only=on;

    root /var/www/testing;
    index index.php

    # Make site accessible from http://localhost/
    server_name localhost;

    location / {
        try_files $uri $uri/ /index.php;
    }

    location ~ .php${
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

        #fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_pass 192.168.1.2:9000;
        fastcgi_index index.php;
        include fastcgi_params;
    }

}

然后我尝试用https://github.com/jpetazzo/pipework创建连接,这就是为什么fastcgi_pass 192.168.1.2:9000;.I尝试使用IP直接从容器,但没有.

当我尝试用lynx打开页面时,我有BadGateway.

我尝试发布端口MASTER_PORT = $(sudo docker端口$MASTER_ID 9000),但没有…
ping没有问题.从nginx Telnet到端口9000保持打开几秒钟,然后“连接关闭…”

谁能解释我在做错什么？
谢谢！

我尝试将fastcgi_pass更改为172.17.42.1:9000; (主机上docker0的地址),然后在主机上启动tcpdump：

tcpdump -i docker0端口9000

我有：

因此,数据包在容器之间…但为什么BadGateway？
