Hello,

I need more guidance on this task, and I think one should restart from
scratch.
This java app "masterpassword-gui" is obviously a graphical frontend,
but I think I didn't reflect this in my dockerfile.

Currently I'm using this dockerfile to build the image:
# Filename: mpw-gui
FROM alpine:latest
RUN apk add openjdk17-jre-headless openjdk17-jre
COPY files/masterpassword-gui.jar
/home/thomas/Software/masterpassword-gui.jar
CMD ["java", "-jar", "/home/thomas/Software/masterpassword-gui.jar"]

tree /home/thomas/Software/container/mpg-gui/
Software/container/mpg-gui/
├── Dockerfile
└── files
└── masterpassword-gui.jar

1 directories, 2 files

The build is successful, but running the container fails.

Could you please advise how to complete this task?

THX
