[Podman] Re: How to build image for own jar file
by Александр Илюшкин
Usually, a GUI application is downloaded to a local computer and
configured to communicate with services over the network.
Since this turned out to be inconvenient, instead of making GUI
applications, people usually make web applications, available through
a browser.
They can be put into a docker container and made accessible by opening
a port through the EXPOSE instruction.

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.

[Podman] Re: podman slowly shows logs on windows

Hey Александр,
Do you see a difference when you run this on the WSL prompt? If you do "wsl
-d podman-machine-default”, then podman logs <container>?

by Александр Илюшкин
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-df4...

gpgme-devel is provided in the

sure you have that enabled.

I also noticed that podman-machine does not start after reboot, I have
to start it manually.
There is also a bug fixed in 4.6 version.

I'm thinking more along the lines of being able to have Podman deploy
run containers/pods/etc. across different machines and centrally
manage them from a single interface. Particularly where I've got a
main x86 node and a bunch of crappy ARM SBCs to run stuff on.

Currently it is using Podman 3.4.2, due to still using Ubuntu 20.04...
There were some ugly crashes with that when rebuilt with go1.19, so the ISO
