Question

当我监听主机的端口9000（使用tcpdump）并向docker容器的URL（仅http://localhost:80）发出请求时，我看到此时捕获了2个数据包。但是，当我在用PhpStorm或xdebug's command line debug client（无参数）收听时，它们没有任何反应。

当我禁用容器中的xdebug（通过注释xdebug.remote_enable=1）并发出请求时，主机的端口9000没有任何反应，这使我认为xdebug正常工作。

当我在本地运行相同的代码时，相同的xdebug命令行工具（也没有参数）确实开始调试，这使我认为我使用了正确的工具。

我确实尝试遵循容器xdebug.remote_host文件中的IP，以xdebug.ini的形式出现（相同的结果）：

172.17.0.1（通过在主机上运行ip -4 addr show docker0 | grep -Po 'inet \K[\d.]+'返回）
172.18.0.1（通过在容器中运行/sbin/ip route|awk '/default/ { print $3 }'返回）
≈10个其他人，我不记得自己是怎么得到的（尝试了很多事情）

我想念什么？我应该检查什么？

在主机上：

捕获的错误数据包的内容（从容器发送，未打开dbgp客户端）：

正确捕获的数据包的内容（从主机发送，也无需dbgp客户端侦听）：

（不同输出中的时间戳有所不同，因为我去除了重复的部分）

您在哪里可以找到Xdebug + Docker的问题？
