无法从 MacOS 中的主机访问 tezos 节点（在 Docker 中）

Question

尝试访问 docker 容器内的节点进程运行时获取 "Curl Error 52 Empty reply from server"。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。

但是当尝试获取访问 RPC 请求时出现错误，如："Curl Error 52 Empty reply from server"。 (P.S.- 以上问题针对Mac OS X)

Docker 版本：2.3.0.0 (44472) 通道：边缘引擎：19.03.8

Running a Tezos Node inside Docker

我们尝试从主机访问的端口是 18731:

docker port <container_name>

给出：

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：

在 docker 中访问网络服务器运行与运行基于 RPC 的网络有何不同？

Answer 1

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 容器内的任何地方或映射端口时使用 127.0.0.1 或本地主机。而使用 0.0.0.0 将解决此问题。希望这对你有所帮助。
