java - 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。我现在想容器化此应用程序，但出现以下错误:

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:

1) Install Linux

2) Install JDK

3) Copy over the folder containing the JAR

4) run the docker container which would bring up the GUI ( not the linux front-end , not using a vnc is preferred).

我在 Windows 上的终端上使用 Xlaunch，并且能够使用它在 docker 上启动 Firefox。

这是第一个 docker 文件

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

这是第二个 docker 文件

FROM alpine:3.2

我在第一个 dockerfile 中遇到此错误

我在 mkdir/opt 行的第二个 dockerfile 中收到权限错误。

有人可以告诉我在 Windows 中执行此操作的正确方法吗？

做了一些更多的研究，通过点击和试用以下代码似乎启动了 GUI，之后出现了一些错误，但这一定是由于 GUI 本身的其他一些问题造成的:

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
