Setting hostname in Kubernetes Pod Yaml
by Rudolf Vesely 09 Feb '22

09 Feb '22

Hi Everybody, I’m not sure if this is a Kubernetes standard behavior or Podman bug/feature. When I: ================================================== tee test-this.yml <<< 'apiVersion: v1 kind: Pod metadata: name: mypod123 spec: hostname: test456 containers: - name: first image: docker.io/library/debian:bookworm command: ["/bin/sleep"] args: - "infinity" - name: second image: docker.io/library/debian:bullseye command: ["/bin/sleep"] args: - "infinity" - name: third image: docker.io/library/ubuntu:focal command: ["/bin/sleep"] args: - "infinity"' podman play kube test-this.yml ================================================== and then: ================================================== podman exec mypod123-first cat /etc/hostname test456 podman exec mypod123-first hostname mypod123 ================================================== And when I "podman exec -it mypod123-first bash" I can see "root@mypod123" in the prompt. In other words "spec.hostname" does change "/etc/hostname" but does not apply it like reboot on host would do. Can anyone please tell me, is it a bug or feature? Thank you. Kind regards, Rudolf Vesely

Upgrade Recommendations from 1.4.2 to 3.3.1
by Christopher.Miller＠gd-ms.com 07 Feb '22

07 Feb '22

Hello, currently running Podman 1.4.2 on RHEL 8.1 and want to upgrade 3.3.1 so we can take advantage of the newer features (like networking). I am running containers currently in the 1.4.2 environment. Is there anything to think of or do before doing an upgrade, or a best practice? Thanks Chris Miller Altron INC. 703-814-7647 Christopher.miller(a)altroninc.com Christopher.Miller(a)gd-ms.com<mailto:Christopher.Miller@gd-ms.com>

Hi guys. If I remember correctly both root full & less containers could talk(cni net) to localhost which was the host itself - was the removed recently or my memory fails me and that never worked? (if so then why?) many thanks, L

=?utf-8?q?=5BPodman=5D?=(Un)subscription is broken

When I subscribed to this list, it took multiple days before I got confirmation. By the moment when I gotten it I no longer needed the mailing list. On top of that, now that I'm trying to unsubscribe, sending a mail to podman-leave(a)lists.podman.io does nothing at all. Over last 3-4 days I send like a dozen of them, it does absolutely nothing.

Podman 4.0rc4 and network packages
by Brent Baude 04 Feb '22

04 Feb '22

Today, we have cut a Podman 4.0rc4 release upstream. We would love for people to begin testing this with their usual Podman usage. Moreover, as has been shared at length over the last six months, Podman 4 will default to a new network stack developed by our team. This is something we really would like people to test as networking has always been problematic for Podman. I have posted a set of brief instructions for testing Podman 4 with its network stack. Please consult https://podman.io/blogs/2022/02/04/network-usage.html for those instructions. As usual, we would love your feedback. Please submit a github issue should you find any problems -> https://github.com/containers/podman/issues We are likely less than three weeks away from its final 4.0 release. Any help the community can provide now will benefit the release and users of Podman 4. Brent

How do you add directory listing to the php:7.2-apache image?
by Jeroen Verhoeckx 03 Feb '22

03 Feb '22

Hello Podman developers, I signed up for this mailing list for a different question, but because I already solved that one, I will ask another. It’s not really related to Podman but to a specific container image. Hopefully you don't mind for one time. Question: Does somebody know how I can add directory listing to the [php:7.2-apache](https://hub.docker.com/_/php/) image? When I look inside the container it should be enabled (see code below) but when I add directories and files to the mounted volume (see command below) the directories and files aren't shown? Content of the file /etc/apache2/apache2.conf : <Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory> I use the following command to run the image: podman run --rm --detach -p 8080:80 --name webserver -v ~/Webserver:/var/www/html:Z php:7.2-apache I don't know why the code Options Indexes doesn't work as expected. Does somebody has an idea? Your sincerely, Jeroen Verhoeckx -------------------------------------------------------- Support the independent web, use [Firefox](https://www.mozilla.org/en-US/firefox/new/)

podman volume performance
by Michael Ivanov 03 Feb '22

03 Feb '22

Greetings, I am running oracle using podman volume for data (it is not for production, of course, development only). So far I did not notice anything noticeably wrong about it, but today I observed, that adump directory has a lot of files and decided to clean it up (just rm -rf adump). As of time of writhing the command runs for about half an hour and did not yet complete. Ten minutes ago I checked number of remaining files and it was about 350000. The removal goes at a rate on about 1000 files per minute or so. On hosting system fuse-overlayfs process takes 99% cpu. My system is rocky linux (former centos) 8.5. I installed podman from standard rocky linux repo, no external repos were used. Podman version is3.2.3, crun 0.20.1 is used fpr container runtime. Underlying fs for container storage is ext4. I did not do any special setup/configuration at all, apart from creating an lvm for co=ntainer storage and mounting it under /home/xxxx/.local/share/containers (podman runs rootless). Is this behaviour normal? Best regards, -- \ / | | (OvO) | Михаил Иванов | (^^^) | | \^/ | E-mail: ivans(a)isle.spb.ru | ^ ^ | |

journald log driver not working
by Ranbir 01 Feb '22

01 Feb '22

Hello Everyone, I'm testing out using journald for logging from one of my containers. I think I configured it correctly, but I don't see anything in the path I passed to it. Here's the create command I used: CreateCommand": [ "podman", "run", "-d", "--name", "postgrey", "--pod", "mailman", "--volume", "postgrey:/var/spool/postfix/postgrey:Z", "--log-driver", "journald", "--log-opt", "path=/var/log/containers/postgrey.log", "postgrey" ], /var/log/containers is empty: # ls -l /var/log/containers/ total 0 Docker's docs on retrieving the logs with journalctl don't show me anything: journalctl CONTAINER_NAME=postgrey -- Logs begin at Wed 2022-01-19 17:04:20 EST, end at Tue 2022-01-25 18:40:27 EST. -- -- No entries -- Incidentally, I used podman to crate the systemd unit files for the pod and dumped them into /etc/systemd/system. I'm starting, stopping, etc the pod using systemctl. Using journald for logging means the container's logs get written to the host's journal, right? If that's true, what am I doing wrong? -- Ranbir

Hi guys, does anybody see this, for rootless containers? -> $ podman container logs -f nextcloud.in.ccn Error: initial journal cursor: failed to get cursor: cannot assign requested address container is created with: -> $ podman run -d --network podman --restart=always --privileged --security-opt label=disable....

Why it is impossible to run some containers on some platforms?
by Pavel Sosin 01 Feb '22

01 Feb '22

Dear colleagues, please, compare CRun and runc implementation. CRun lacks some dependencies like seccomp,etc. Most RedHat UBI, ... images were cut from the distro together with systemd2, logind, resourced, oomd, ... Running bash in the systems with user's sessions managed by systemd2 requires 1. Communication with systemd on the host to put the container cgroup into the right place. 2. Starting the user's session inside the container. You can see it clearly if you pull/from/unshare/mount ubi or fedora image using buildah. /bin/bash in the userspace ,I suppose can run correctly only inside user's session and borrows session's resources. What about annotating "systemd" images and initializing them using systemd by the default?
