在Docker中启用Wildfly域模式的debugging – 端口已经在使用
我为一组开发人员提供了完整的docker环境，主要包括Wildfly，MySQL和Apache。 我根据生产预先configuration了所有图像，现在开发人员已经请求了另一个选项：能够使用intellij来debugging正在运行的野蛮奴隶。
设置：我设置了一个虚拟机来托pipeDocker，因为人们使用不同的操作系统。 我转发必须从承载VM的本地计算机可访问的端口。 这个工作，他们可以访问数据库，野蛮的pipe理等虚拟机configuration和端口的屏幕截图： debian机托pipe泊坞
Dockerfile的主机debugging（这不是工作）：

有两件事要注意：
-agentlib:jdwp=transport=dt_socket,address=0.0.0.0:8787,server=y,suspend=n ERROR: transport error 202: bind failed: Address already in use
所以港口应该在使用，使用netstat我不能看到它：

我已经尝试过的事情：更改-Djava.awt.headless=t rue -agentlib:jdwp=transport=dt_socket,address=0.0.0.0:8787 -Djava.awt.headless=t rue -agentlib:jdwp=transport=dt_socket,address=8787到-Djava.awt.headless=t rue -agentlib:jdwp=transport=dt_socket,address=8787
将端口从8787更改为其他内容。 暴露端口，不暴露端口。 Server = y，Server = n
我正在运行：Docker版本1.11.2，Wildfly 8.2 Dockernetworking检查：

任何想法或build议将不胜感激。 提前致谢。
通过将值放在JAVA_OPTS环境variables中，它将用于进程控制器和主机控制器。 您看到了错误，因为当过程控制器尝试绑定到端口8787时，主机控制器已经有一个侦听代理侦听。
我的猜测是你想在服务器上实际debugging你的应用程序。 如果在你的host-slave.xml中是这种情况，你需要添加类似下面的东西到特定的服务器。
<jvm name="default"> <jvm-options> <option value="-agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"/> </jvm-options> </jvm>
例：
<servers> <server name="server-one" group="main-server-group"> <jvm name="default"> <jvm-options> <option value="-agentlib:jdwp=transport=dt_socket,address=8787,server=y,suspend=n"/> </jvm-options> </jvm> </server> <server name="server-two" group="other-server-group"> <!-- ~ server-two avoids port conflicts by incrementing the ports in ~ the default socket-group declared in the server-group --> <socket-bindings port-offset="150"/> </server> </servers>
