在Docker上运行Java Swing GUI应用程序

Question

我正在尝试使用Windows中的docker工具箱运行自定义java swing GUI。我现在想要容器化这个应用程序，但是得到以下错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: 
/opt/jdk1.8.0_202/jre
/lib/amd64/libawt_xawt.so: libXext.so.6: cannot open shared object file: 
No such file or directory

我正在运行一个DockerFile。设置为：

3）复制到包含JAR的文件夹上

4）运行docker容器，该容器将启动GUI（不是linux前端，最好不使用vnc）。

我将Xlaunch用于windows上的终端，并且能够使用它在docker上启动一个firefox。

FROM anapsix/alpine-java
COPY ./myJarFolder /home/myJarFolder
CMD ["java","-jar","/home/myJarFolder/myJarFile.jar"]

FROM alpine:3.2

我在mkdir/opt行得到第二个dockerfile的权限错误。

谁能请让我知道正确的方法做它在Windows。

我做了一些更多的研究，通过命中和试用，下面的代码似乎启动了GUI，之后有一些错误，但这一定是由于GUI本身的一些其他问题：

FROM openjdk:8

# Set environment

ENV JAVA_HOME /opt/jdk

ENV PATH ${PATH}:${JAVA_HOME}/bin   

# COPY myJarFolder from local repository to the image

COPY ./myJarFolder /usr/local/myJarFolder

# Start the image with the jar file as the entrypoint

ENTRYPOINT ["java", "-jar", "/usr/local/myJarFolder/myJarFile.jar"]

# EOF
