Hello, I need more guidance on this task, and I think one should restart from scratch.

Hi, mate.

I believe you can use this answer on SO https://stackoverflow.com/a/35062090 replacing `docker` with `podman` as it fully supports docker API.

So I would write a file named `Dockerfile`:

FROM openjdk:11 MAINTAINER t.schneider@getgoogleoff.me COPY~/.mpw-gui/masterpassword-gui.jar /home/masterpassword-gui.jar CMD ["java","-jar","/home/masterpassword-gui.jar"]

Notice that I used FROM openjdk:11, you don't have to build your own separate openjdk image as it's already built by guys from openjdk, please use your current project version of JDK for it: https://hub.docker.com/_/openjdk

Build your image:

podman build -t imageName .

Now invoke your program inside a container:

podman run --name myProgram imageName

Now restart your program by restarting the container:

podman restart myProgram

Your program changed? Rebuild the image!:

podman rmi imageName podman build -t imageName .

Additionally, usually we don't build images by hand, we use maven or gradle for this.

For instance, google created a tool called JIB, which creates OCI images with java programs automatically: https://cloud.google.com/java/getting-started/jib

Also, we use this maven plugin to build docker image with jar file of our project without writing Dockerfile at all: https://dmp.fabric8.io/

It should work the same way with both docker and podman.

Hello,

I have successfully build docker image "sapmachine", a build of OpenJDK.

Now I want to build my own image to run my own jar file. This jar file is located in ~/.mpw-gui/masterpassword-gui.jar, and with locally installed OpenJDK I would run this command: java -jar .mpw-gui/masterpassword-gui.jar

Could you please advise how to build my own image for this java application?

Understood. But what is the solution then to deploy this application? Am 05.12.23 um 06:34 schrieb Александр Илюшкин:

TLDR: You will not be able to run graphical applications in containers.

What do you expect to see as a result of launching the gui application? There is no graphics system in alpine by default, even if you add it there, the graphics window somehow needs to be displayed on your local machine, this will require certain settings to broadcast the graphics system over the network.

containers usually contain services that are accessible over the network through an open network port

Why? For me the following options to "podman run" command allow to run kdevelop inside the container:    podman run ..... --env DISPLAY=unix$DISPLAY --volume /tmp/.X11-unix:/tmp/.X11-unix ..... Alternatively I can also run vnc server inside the container. Rgrds, -- Михаил Иванов

Thanks, Michael. Yeah, so to summarize everything 1. Decide, whether you have an option to rewrite your gui app to webapp, or your only option is gui. 2. For gui deployment in podman, you have to add additional graphical libraries for Linux, install them inside your dockerfile. 3. Google for articles of how to use graphical environment inside a docker container, this, for instance: https://sgrgyanchandani.medium.com/gui-inside-centos-docker-container-df49f5... С уважением, А.

Hello,

I have to say that I run many graphical applications via podman and this saves my a... The problem are for example CAD-software vendors. Their (very powerful and expensive) software *only* runs on e.g. RHEL7. Then containers are your saviour! Just use the centos7 container and "yum" the needed packages for a graphical system and your in business (while keeping your desktop machine bleeded edge). Much less overhead than a full virtual machine.

I love podman and the possibility to also run graphical applications in them. (normally in a vnc-server, as vnc is also such a great tool to improve your life).

Viele Grüße

Michael
