我正在尝试使用 jprofiler 12.0.3 设置一个 alpine linux docker 容器,以便我可以远程连接到它。
在我的Dockerfile
:
FROM adoptopenjdk/openjdk11-openj9:alpine-slim
...
RUN wget https://download-gcdn.ej-technologies.com/jprofiler/jprofiler_linux_12_0_3.tar.gz -P /jprofiler/ && tar -xzf jprofiler_linux_12_0_3.tar.gz -C /jprofiler && rm /jprofiler/jprofiler_linux_12_0_3.tar.gz
ENTRYPOINT ["./startup.sh"]
在我的startup.sh
文件中:
...
JAVA_OPTS="$JAVA_OPTS -agentpath:/jprofiler/jprofiler12.0.3/bin/linux_musl-x64/libjprofilerti.so=port=8849,nowait"
...
但是,当我使用上面的 Dockerfile 构建并运行 docker 映像时,我得到:
Starting app with JAVA_OPTS: -agentpath:/jprofiler/jprofiler12.0.3/bin/linux_musl-x64/libjprofilerti.so=port=8849,nowait
JProfiler> Protocol version 64
JProfiler> Thread status info workaround enabled.
JProfiler> OpenJ9 JVMTI version 1.1 detected.
JProfiler> Java 11 detected.
JProfiler> Don't wait for frontend to connect.
JProfiler> 64-bit library (musl)
JProfiler> Could not locate the config file.
JProfiler> Please specify config=[config filename].
JProfiler> If you are running JProfiler's frontend on a different
JProfiler> machine you have to copy the file jprofiler_config.xml to this
JProfiler> computer. The file is located in $HOME/.jprofiler12 or
JProfiler> in C:\Users\[username]\.jprofiler12.
如果我将基本图像更改为像这样的热点图像,例如:
FROM adoptopenjdk:11-jre-hotspot-focal
...
RUN wget https://download-gcdn.ej-technologies.com/jprofiler/jprofiler_linux_12_0_3.tar.gz -P /jprofiler/ && tar -xzf jprofiler_linux_12_0_3.tar.gz -C /jprofiler && rm /jprofiler/jprofiler_linux_12_0_3.tar.gz
ENTRYPOINT ["./startup.sh"]
并startup.sh
:
...
JAVA_OPTS="$JAVA_OPTS -agentpath:/jprofiler/jprofiler12.0.3/bin/linux_musl-x64/libjprofilerti.so=port=8849,nowait"
...
我得到以下输出,我可以使用 JProfiler 远程连接到这个 JVM:
Starting app with JAVA_OPTS: -agentpath:/jprofiler/jprofiler12.0.3/bin/linux-x64/libjprofilerti.so=port=8849,nowait
JProfiler> Protocol version 64
JProfiler> Java 11 detected.
JProfiler> Don't wait for frontend to connect.
JProfiler> 64-bit library
JProfiler> Starting up without initial configuration.

您是否碰巧知道为什么 alpine 映像会以这种方式运行,以及是否有任何方法可以解决此配置文件问题?
