shouldn't the current directory be the default context for "podman build"?

by Robert P. J. Day

"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

mqueue msg_max in rootless container

by Michael Ivanov

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 | ^ ^ | |

=?utf-8?q?=5BPodman=5D?=(Meta) Security warnings for podman mailing list

by Joost Molenaar

Hi all, for ~every message posted to this list, some email clients display an error, in my case "This email has failed its domain's authentication requirements. It may be spoofed or improperly forwarded." These are the authentication results for a recent message from the list: Authentication-Results: mailin008.protonmail.ch; arc=none smtp.remote-ip=8.43.85.227 Authentication-Results: mailin008.protonmail.ch; dkim=none Authentication-Results: mailin008.protonmail.ch; spf=none smtp.mailfrom=lists.podman.io Authentication-Results: mailin008.protonmail.ch; dmarc=fail (p=none dis=none) header.from=redhat.com If I understand correctly, Mailman has an option[1] to change the From: header in the email and add the original sender's name and address to the Reply-To: header, which leads to a slightly worse user experience, but is better for security because it reduces the number of false positives we get exposed to. So my question is, could we enable DMARC mitigation to reduce warning fatigue? Regards, Joost Molenaar [1]: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/handlers...

Using Eclipse with Podman Engine on Linux

by Mehdi Haghgoo

I want to use Eclipse with Podman backend on Windows. I have Podman Desktop installed and the podman context is: Name URI Identity Default podman-machine-default ssh://user@localhost:64926/run/user/1000/podman/podman.sock C:\Users\me\.ssh\podman-machine-default true podman-machine-default-root ssh://root@localhost:64926/run/podman/podman.sock C:\Users\me\.ssh\podman-machine-default false Eclipse's Docker tooling has a setting for Container engine like the following: It takes either a unix socket or a TCP connection, but none of them accept the value specified by Podman URI like ssh://user@localhost:64926/run/user/1000/podman/podman.sock. Is there a workaround I can connect Eclipse to Podman engine on Windows?

Question about expectations when running play kube and using volumes

by Martin Jackson

Hello, Yesterday I opened https://github.com/containers/podman/issues/16348 - the heart of the issue is that when starting a pod with volumes, when the pod comes down, it can't come up again without removing the volumes. I'm open to the idea that I can improve how I'm doing the deployment; but it seems that having to remove volumes before restarting the pod does not seem like something we want to require. If we were to have another stateful service running under podman (postgres? strimzi?), having the pod fail to restart after a reboot seems like it might be a big issue. What do you think? -- Martin Jackson Sr. Principal Software Engineer, Ecosystem Engineering Red Hat <https://www.redhat.com/> mhjacks(a)redhat.com @RedHat <https://twitter.com/redhat> Red Hat <https://www.linkedin.com/company/red-hat> Red Hat <https://www.facebook.com/RedHatInc> <https://www.redhat.com/> <https://redhat.com/summit>

podman container storage backup

by Michael Ivanov

Greetings, I make periodic backups of my laptop where I use some podman containers. To perform a backup I just invoke rsync to copy my /home/xxxx/.local/share/containers directory to nfs mounted filesystem. Containers are running, but quiescent, no real activity occurs. Is this a correct way to back up or is there anything special about container directory to be taken into account? As far as I understand some hash-named subdirectories are shared between different containers and images using special kind of mounts, can this lead to duplicate copies r inconsistencies? Underlying fs is btrfs. Thanks, -- \ / | | (OvO) | Михаил Иванов | (^^^) | | \^/ | E-mail: ivans(a)isle.spb.ru | ^ ^ | |
