# in environment ?
by lejeczek 09 Aug '25

09 Aug '25

Hi guys. Do you use # in your envs? I wonder if it's just me having issues with those. For a test, to reproduce the issue, 'ghost' web solution would be easy & quick: -> $ podman run -dt ...................... --env database__client=mysql --env database__connection__host=11.1.0.1 --env database__connection__user=ghostadm --env database__connection__password='xyz#admghost' --env database__connection__database=ghost_xyz --env url=https://ghost.xyz So far all I've tried with 'database__connection__password' failed, quoting &| escaping. I often use # - does anybody have a way to make it work? many thanks, L.

RunRoot & mistaken IDs
by lejeczek 03 Jul '25

03 Jul '25

Hi guys. I experience this: -> $ podman images WARN[0000] RunRoot is pointing to a path (/run/user/1007/containers) which is not writable. Most likely podman will fail. Error: creating events dirs: mkdir /run/user/1007: permission denied -> $ id uid=2001(podmania) gid=2001(podmania) groups=2001(podmania) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 I think it might have something to do with the fact that I changed UID for the user, but why would this be? How troubleshoot & fix it, ideally without system reboot? many thanks, L.

shouldn't the current directory be the default context for "podman build"?
by Robert P. J. Day 12 Dec '24

12 Dec '24

"man podman-build" suggests that the context argument is optional: SYNOPSIS podman build [options] [context] podman image build [options] [context] ... If no context directory is specified, then Podman will assume the current working directory as the build context, which should contain the Containerfile. but if i have a directory with nothing but a Containerfile, i get: $ podman build Error: no context directory specified, and no containerfile specified $ OTOH, specifying context of current directory: $ podman build . STEP 1: FROM alpine:latest ... etc etc ... thoughts? rday

Re: podmansh and persistent container
by Felix Niederwanger 31 May '24

Hello, I managed to achieve my goal to get a persistent container for my non-root user with podmansh working. In the end it was surprisingly easy to achieve, once I figured out which pieces to put together. I wrote the steps down in https://www.feldspaten.org/2024/05/31/Persistent-container-podmansh/ There is a TL;DR and a longer step-by-step guide. I put the link to the article also in https://github.com/containers/podman/discussions/19620. My takeaway was the elegance of `podmansh`. It's really just a `podman exec -ti podmansh /bin/sh` (I love this simplicity!). Once I figured out that it's really this, the rest was relatively easy. Hope the guide is helpful for someone else as well. Cheers!

[Rawhide Test Day] Podman 5.1 Test Day 2024-05-23
by Sumantro Mukherjee 22 May '24

22 May '24

Hey Folks! We will be testing Fedora 41 with the new update in Podman 5.1. To ensure a smooth transition, the Podman team and the Quality team of Fedora have decided to host a test day[1]. The idea is for users to test Podman 5.1 on a Fedora Rawhide machine and submit results in the Test Day App[2]. If you have spare cycles or use Podman as a daily driver, it will be great to have some folks try out and report bugs right away. We will want more Karmas on[3] and any following builds for Podman 5.1 [1] https://fedoraproject.org/wiki/Test_Day:2024-05-23_Podman_5.1 [2] https://testdays.fedoraproject.org/events/188 [3] https://bodhi.fedoraproject.org/updates/FEDORA-2024-7d9e4ee012 -- //sumantro Fedora QE TRIED AND PERSONALLY TESTED, ERGO TRUSTED

by Matt Heon 10 May '24

10 May '24

Hi all, We've just released Podman 5.0.3. This is a security update that addresses CVE-2024-3727, a vulnerability in the containers/image library which allows attackers to trigger unauthorized registry accesses on behalf of the victim. There are also several small bugfixes included, but most fixes and new features will wait until Podman 5.1, which we expect to release later this month. Thanks, Matt Heon

logging through up to host / systemd init container
by Leon Fauster 10 May '24

10 May '24

I wonder whats the current best approach for having the logs of one container accumulated at the host layer (journald). The container runs systemd/journald and is started via a quadlet config with LogDriver=passthrough. So, everything that the container spells out via stderr/stdout is captured at the host layer. How to pass everything of the container journald to the host journald? I played with LogTarget in /etc/systemd/system.conf without success. I'd really appreciate any ideas! -- Leon
