我无法通过 jmx(使用 VisualVM)将 Java 应用程序连接到本地网络中远程主机上的 Docker 容器中。
案例 1:Java 应用程序到客户端的 Docker 容器中:
连接到应用程序(端口 6830) - 工作
连接到 jmx(端口 6831) - 工作
java -Dhttp.port=9010 \
-Dcom.sun.management.jmxremote.port=9011 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9012 \
-jar application.jar
docker run -d \
-p 6830:9010 \
-p 6831:9011 \
--name container_name \
base_image \
setup.sh
案例 2:远程主机上没有 Docker 容器的 Java 应用程序:
连接到应用程序(端口 6830) - 工作
连接到 jmx(端口 6831) - 工作
java -Dhttp.port=6830 \
-Dcom.sun.management.jmxremote.port=6831 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=6832 \
-jar application.jar
案例 3:Java 应用到远程主机上的 Docker 容器中:
连接到应用程序(端口 6830) -工作
连接到 jmx(端口 6831) -不工作
java -Dhttp.port=9010 \
-Dcom.sun.management.jmxremote.port=9011 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
-Dcom.sun.management.jmxremote.local.only=false \
-Dcom.sun.management.jmxremote.rmi.port=9011 \
-Djava.rmi.server.hostname="192.168.0.2" \
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9012 \
-jar application.jar
docker run -d \
-p 6830:9010 \
-p 6831:9011 \
--name container_name \
base_image \
setup.sh
服务器上的结果netstat -tunelp | grep 6831
:
