让JavaFX 11应用程序在Docker上工作

Question

我正在尝试让一个可以在我的机器上完美运行的应用程序在docker上运行，这是我的docker文件：

FROM openjdk:11-jre-slim
VOLUME /tmp
ADD someJar.jar someJar.jar
ADD lib lib
ADD config.properties config.properties
ENTRYPOINT ["java", "-javaagent:lib/aspectjweaver-1.9.2.jar", 
    "-javaagent:lib/spring-instrument-5.1.6.RELEASE.jar", "--module-path", 
    "lib/javafx-sdk-11.0.2", "--add-modules=javafx.controls", "- 
    Dprism.verbose=true", "-jar","someJar.jar"]

我还尝试将其基于高山openjdk11版本，其结果相同：

FROM adoptopenjdk/openjdk11:alpine
VOLUME /tmp
RUN apk update && apk add libx11 mesa-gl gtk+3.0 && apk update
ADD someJar.jar someJar.jar
ADD lib lib
ADD config.properties config.properties
ENTRYPOINT ["java", "-javaagent:lib/aspectjweaver-1.9.2.jar", "-javaagent:lib/spring-instrument-5.1.6.RELEASE.jar", "--module-path", "lib", "--add-modules=javafx.controls", "-Dprism.verbose=true", "-jar","someJar.jar"]

The lib folder contains the linux flavor of the openJFX runtime (.so files and .jar files). I am developing this on a Windows machine with the Windows-equivalent of the openJDK runtime and it works perfectly. When running the container I get the following output :

Prism pipeline init order: es2 sw

Any idea how i can get a Java app based on OpenJFX11 to work in Docker?

******UPDATE******

I made some progress on this. I found that putting my openJFX runtime files DIRECTLY in my lib folder made it progress a bit more. The new error became this:

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

After a bit of research, i added this RUN command in my dockerfile :

RUN apt-get update && apt-get install libgl1-mesa-glx -y

This gives me a new stacktrace :

******ANOTHER UPDATE******

Digging through the JavaFX code in the GtkApplication.class file, this is the section that is failing :

int libraryToLoad = _queryLibrary(gtkVersion, gtkVersionVerbose);

AccessController.doPrivileged((PrivilegedAction<Void>) () -> {
        if (libraryToLoad == QUERY_NO_DISPLAY) {
            throw new UnsupportedOperationException("Unable to open DISPLAY");
        } else if (libraryToLoad == QUERY_USE_CURRENT) {
            if (gtkVersionVerbose) {
                System.out.println("Glass GTK library to load is already loaded");
            }
        } else if (libraryToLoad == QUERY_LOAD_GTK2) {
            if (gtkVersionVerbose) {
                System.out.println("Glass GTK library to load is glassgtk2");
            }
            NativeLibLoader.loadLibrary("glassgtk2");
        } else if (libraryToLoad == QUERY_LOAD_GTK3) {
            if (gtkVersionVerbose) {
                System.out.println("Glass GTK library to load is glassgtk3");
            }
            NativeLibLoader.loadLibrary("glassgtk3");
        } else {
            throw new UnsupportedOperationException("Internal Error");
        }
        return null;
    });

Do i have a missing library or something?

... HELP?

Thanks

Answer 1

我终于有了这个工作！我必须在Windows主机上安装VcXsrv并将其添加到docker run命令中：

-e DISPLAY=MY IP ADDRESS:0.0

我的应用现在可以正常启动并在实际开始Spring初始化之前输出以下内容：

Prism pipeline init order: es2 sw
Using Double Precision Marlin Rasterizer
Using dirty region optimizations
Not using texture mask for primitives
Not forcing power of 2 sizes for textures
Using hardware CLAMP_TO_ZERO mode
Opting in for HiDPI pixel scaling
Prism pipeline name = com.sun.prism.es2.ES2Pipeline
Loading ES2 native library ... prism_es2
    succeeded.
GLFactory using com.sun.prism.es2.X11GLFactory
MESA-LOADER: failed to open swrast (search paths /usr/lib/xorg/modules/dri)
libGL error: failed to load driver: swrast
Prism-ES2 Error : GL_VERSION (major.minor) = 1.4
(X) Got class = class com.sun.prism.es2.ES2Pipeline
GraphicsPipeline.createPipeline: error initializing pipeline com.sun.prism.es2.ES2Pipeline
*** Fallback to Prism SW pipeline
Prism pipeline name = com.sun.prism.sw.SWPipeline
(X) Got class = class com.sun.prism.sw.SWPipeline
Initialized prism pipeline: com.sun.prism.sw.SWPipeline
MESA-LOADER: failed to open swrast (search paths /usr/lib/xorg/modules/dri)
libGL error: failed to load driver: swrast
vsync: true vpipe: false 

我仍然会尝试解决一些错误，但实际上现在开始！

根据要求的完整dockerfile，我仍在努力解决导致其回退到棱镜管道的错误，稍后将更新：

FROM adoptopenjdk/openjdk11:alpine
VOLUME /tmp
RUN apk update && apk add libx11 mesa-gl gtk+3.0 mesa-dri-swrast mesa-demos 
    && apk update
ADD someJar.jar someJar.jar
ADD lib lib
ADD config.properties config.properties
ENTRYPOINT ["java", "-javaagent:lib/aspectjweaver-1.9.2.jar", "-javaagent:lib/spring-instrument-5.1.6.RELEASE.jar", "--module-path", "lib", "--add-modules=javafx.controls", "-Dprism.verbose=true", "-Djava.awt.headless=true", "-jar","someJar.jar"]

******最终设置******

我钻研了libGL错误，使ES2管道正常工作的麻烦甚至不值得我满足。它会涉及Nvidia和CUDA驱动程序的混乱，并且完全没用，因为无论如何我的应用程序只是一个后台服务。这是使一切正常工作的最终设置：

Dockerfile（出于与我的其他应用程序的一致性而切换回openjdk并找出了要安装的最小软件包）

FROM openjdk:11-jre-slim
RUN apt-get update && apt-get install libgtk-3-0 libglu1-mesa -y && apt-get update
VOLUME /tmp
ADD someJar.jar someJar.jar
ADD lib lib
ADD config.properties config.properties
ENTRYPOINT ["java", "-javaagent:lib/aspectjweaver-1.9.2.jar", "-javaagent:lib/spring-instrument-5.1.6.RELEASE.jar", "--module-path", "lib/javafx-sdk-11.0.2", "-jar", "someJar.jar"]

Docker构建命令

docker build -f Dockerfile -t some_service .

Docker运行命令

docker run -t --name Some_Service -e DISPLAY=MY IP:0.0 -e SOME_VARIABLE= --link mySQLSRV:mysql some_service

希望这对某人有帮助，这花了我几天时间才能上班！
