# 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

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

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?

fs.mqueue.msg_max rootless problem
by Михаил Иванов 30 Nov '23

30 Nov '23

Hallo, Is it possible to get podman to propagate current host fs.mqueue.msg_max value to rootless container? I can do that if I specify --ipc host when running the container, but this also exposes other ipc stuff from host to container, including shared memory, which I do not want. If I specify --sysctl fs.mqueue.msg_size=64 to podman it gives me "OCI permission denied" error, even when my host setting (256) is greater than requested value. Thanks, -- Micvhael Ivanov

Podman v4.8.0 Released!
by Ashley Cui 27 Nov '23

27 Nov '23

We’re excited to announce that Podman v4.8.0 has been released! This release includes over 20 features and over 20 bugfixes each. Some highlights include: - *HyperV Support*: Podman machine now supports HyperV as a provider on Windows. - *Heredoc Support*: Containerfiles that contain heredoc syntax can now be built using podman build. - *SQLite*: Podman now defaults to SQLite as its database backend. But don’t worry! If you are still currently using BoltDB, podman will continue to use Bolt, unless you choose to manually use SQLite For a full list of changes, see our GitHub release <https://github.com/containers/podman/releases/tag/v4.8.0> page. Big thanks to our contributors and community! Try it out and let us know what you think! *Upcoming Deprecation Notices*: We are beginning development on Podman 5.0, which will include a bunch of new features, but also a number of breaking changes and deprecations. We are still finalizing what will be done, but a preliminary list is below. Please note that none of these changes are present in Podman 4.8; this is a preview of upcoming changes. - Podman 5.0 will deprecate the BoltDB database backend. Exact details on the transition to SQLite are still being decided – expect more news here soon. - The containers.conf configuration file will be broken up into multiple separate files, ensuring that it will never be rewritten by Podman. - Support for the CNI network backend and Cgroups V1 are being deprecated and gated by build tags. They will not be enabled in Podman builds by default. - A variety of small breaking changes to the REST API are planned, both to improve Docker compatibility and to better support containers.conf settings when creating and managing containers.

mqueue msg_max in rootless container
by Michael Ivanov 27 Nov '23

27 Nov '23

Hallo! I'm trying to run my application in podman rootless container and I stumble on following problem: my program needs /proc/sys/fs/mqueue/msg_max to be at least 256, but in running container this value is just 10. When I try to specify this parameter while running the image (--sysctl 'fs.mqueue.msg_max=256') I get the following error: Error: open /proc/sys/fs/mqueue/msg_max: Permission denied: OCI permission denied and container is not created. My host where container is being run has this parameter set to 256. How can I expose current host setting for msg_max to my container? Best regards, -- \ / | | (OvO) | Михаил Иванов | (^^^) | | \^/ | E-mail: ivans(a)isle.spb.ru | ^ ^ | |

by Tom Sweeney 20 Nov '23

Hi All, Two for one deal! We currently have no topics for tomorrow's (November 21) Podman Community Cabal meeting, and we have been receiving several notes from people saying they will not be attending due to holiday plans. We suspect similar issues will occur at the next meeting, which is scheduled for Wednesday, December 19, 2023. Given that, we have decided to drop tomorrow's meeting and combine the November and December Podman Community Cabal meetings, which will be held on Tuesday, December 12, 2023, at 11:00 a.m. EST (UTC-5). t
