VisualVM无法使用RMI连接docker中的远程tomcat

Question

我正在远程机器上的 docker 容器中运行 tomcat。现在我想用 VisualVM 来连接。我的 docker 启动命令：

docker run -d --name tomcat -p 26000:8080 -p 9090:9090 -p 9091:9091 -v /data/docker/tomcat/webapps:/data/tomcat/webapps -v /data/docker/tomcat/logs:/data/tomcat/logs -e CATALINA_OPTS="-Xms2048M -Xmx2048M -XX:MaxPermSize=256M -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=9090  -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=127.0.0.1"  my.private.hub/tomcat:latest

还有 catalina.log：

但 VisuamVM 无法连接：

'Cannot connect using service:jmx:rmi:///jndi/rmi://192.168.0.119:9090/jmxrmi'

其中 192.168.0.119 是远程主机的地址。

Answer 1

这个

-Djava.rmi.server.hostname=127.0.0.1

应该使用你用来连接它的 docker 主机 ip

-Djava.rmi.server.hostname=192.168.0.119

Answer 2

我试过Marco's answer (also answered here) 但没办法。

最后我可以使用SSH tunnel 进行连接。
