尝试访问在Docker容器内运行的节点进程时，获取“ Curl错误52服务器发空答复”。端口正在公开并正确映射。并且http服务器请求被重定向到主机。
但是在尝试以相同的方式获取访问RPC请求时，出现以下错误：“ Curl错误52来自服务器的空回复”。 （P.S.-以上问题适用于Mac OS X）
Docker版本：2.3.0.0（44472）频道：边缘引擎：19.03.8
在Docker内部运行Tezos节点
我们尝试从主机访问的端口是18731：
docker port <container_name>
给予：
18733/tcp -> 0.0.0.0:18733
18731/tcp -> 0.0.0.0:18731
18732/tcp -> 0.0.0.0:18732
Docker检查结果：

与访问在运行基于RPC的网络的Docker Vs中运行的Web服务器有何不同？
容器内有两个IP，它可能没有监听172.x.x.x IP。您必须避免在Docker容器内部或映射端口的任何地方使用127.0.0.1或localhost。而是使用0.0.0.0将解决此问题。希望这会对您有所帮助。
