Currently podman on Windows/WSL does NOT use coreos. It does use
Fedora. We would need to make sure that pasta is included in the image
that is used for WSL.
Jason could you look into this. I think we should think about changing
the default from slirp4netns to pasta by default in Fedora, which would
fix this issue for all users

I was looking at a few websites which suggest docker exec
this way:
-> $ docker exec 123456789abc bash -c "{command 1} ;
{command 2}"
which does not work, but this does, with/in podman:
-> $ podman container exec freeipa.mine.priv bash -c "source
/root/.bashrc; __ipaCollectBits"

[Podman] Rootless container startup failure at bootup, launches fine manually
by jklaiho＠iki.fi
We've got a Ubuntu 22.04 server running a rootless container as a systemd user service on Podman 4.4.2, using Quadlet. Podman and its dependencies are installed from binary releases on GitHub and/or from source.
Last night the server required a reboot due to some security updates, but the service/container failed to come back up after the boot. In the morning, I was able to manually start it up with `systemctl --user start cms_backend` with no changes to any configuration in the meantime.
Here's the full journalctl output for this unit from last night after the reboot (timestamps removed for brevity):
systemd[746]: cms_backend.service: unit configures an IP firewall, but not running as root.
systemd[746]: (This warning is only shown for the first unit using IP firewalling.)

The container itself is a lightly customized official Python 3.11 image running a Django application, practically identical to others that we're running with no similar issues. The entry point of the image is ["/usr/bin/dumb-init", "--"]. Like I said, the service came up manually just fine several hours after the initial failure, so it doesn't seem likely that this is a problem in our application code.
I can't decipher the error messages, can someone?

[Podman] Re: podman slowly shows logs on windows
by Александр Илюшкин
Guys, I think I know why the logs command is slow, I also started to
use postgresql in podman and I noticed that queries are also slow in
comparison to docker.
I think I might change memory and CPU usage default preferences and
check if that was the case. Could you please point me in the right
direction?

Hi,
see https://github.com/containers/podman/discussions/17717
The biggest problem seems to be the kernel that is shipped in android.

I believe that is what most people do. But we heard of a recent issue in
the latest version of vscode that broke compatibility. Basically podman
and docker command have slightly different output in some of the CLI
calls, which is causing breakage. We were informed that upstream VS Code
was working to handle the difference.
