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"]

我还尝试将它基于 alpine openjdk11 版本，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"]

lib 文件夹包含 openJFX 运行时的 linux 风格(.so 文件和 .jar 文件)。我正在使用与 Windows 等效的 openJDK 运行时在 Windows 机器上开发它，它运行良好。运行容器时，我得到以下输出:

知道如何让基于 OpenJFX11 的 Java 应用程序在 Docker 中工作吗？

******更新******

我在这方面取得了一些进展。我发现将我的 openJFX 运行时文件直接放在我的 lib 文件夹中使它进步了一点。新的错误变成了这样:

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

经过一番研究，我在我的 dockerfile 中添加了这个 RUN 命令:

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

这给了我一个新的堆栈跟踪:

Prism pipeline init order: es2 sw

******另一个更新******

挖掘 GtkApplication.class 文件中的 JavaFX 代码，这是失败的部分:

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;
    });

我是否缺少图书馆或其他东西？

...帮助？

谢谢

最佳答案

我终于搞定了!我必须在我的 Windows 主机上安装 VcXsrv 并将其添加到 docker run 命令:

-e DISPLAY=MY IP ADDRESS:0.0

我的应用程序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，但它实际上现在就开始了!

按要求完整的 dockerfile，我仍在处理导致它回退到 prism 管道的错误，稍后会更新:

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******

我深入研究了 libGL 错误，让 ES2 管道工作的麻烦甚至不值得我的需要。这将涉及与 Nvidia 和 CUDA 驱动程序混淆，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。这是使一切正常的最终设置:

Dockerfile(为了与我的其他应用程序保持一致，切换回 openjdk 并找出要安装的最少软件包)

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

希望这对某人有所帮助，这花了我几天的时间才开始工作!
