Getting a javaFX 11 app to work on docker

Question

I am trying to get an application that works perfectly on my machine to run on docker, here is my docker file :

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"]

I also tried to base it off of the alpine openjdk11 release with the same result :

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

I finally got this to work! I had to install VcXsrv on my Windows host and add this to the docker run command :

-e DISPLAY=MY IP ADDRESS:0.0

My app now starts fine and outputs the following before actually starting the Spring initialization :

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 

There are still some errors that i will try and work through but it actually starts now!

Full dockerfile as requested, I am still working through the errors that are causing it to fallback to the prism pipeline, will update later :

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"]

******FINAL SETUP******

I dug into the libGL errors and the hassle of getting the ES2 pipeline to work is not even worth it for my needs. It would involve messing with Nvidia and CUDA drivers and is totally useless since my app is just a background service anyway. Here is the final setup to make everything work :

Dockerfile (switched back to openjdk for consistency with my other app and figured out the bare minimum packages to install)

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 build command

docker build -f Dockerfile -t some_service .

Docker run command

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

Hope this helps someone, this took me days to get working!
