docker中的nginx容器配置proxy_pass解析不出docker中其他容器的ip

Question

nginx配置文件

location ~ \.php$ {
        fastcgi_pass   phalcon_php:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        fastcgi_param  SCRIPT_FILENAME  /www/cheesi/public$fastcgi_script_name;
        fastcgi_param  HTTPS off;
        include        fastcgi_params;

    }

    location /websocket {
        proxy_pass swoole_php:19600;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

docker-compose建立三个容器，nginx,phalcon_php,swoole_php，nginx配置文件中连接phalcon_php容器时fastcgi_pass phalcon_php:9000这条可以正常运行，但是下面这条proxy_pass swoole_php:19600 报错无效URL invalid URL prefix in /etc/nginx/conf.d/cheesi.conf:57
在nginx容器中可以ping通swoole_php

Answer 1

proxy_pass http://swoole_php:19600;

试一下。
