Hi Team, I have a scenario where I need some help. The application is having multiple containers running with podman run at start up. When firmware update is triggered, some of the files running on x container, need to start tftp container. Can some suggest the steps to start and stop tftp container from x container when Firmware update is getting executed. Thanks in advance for your help. Thank you

Error: netavark: failed configure macvlan: IO error: failed to add route: Invalid argument (os error 22)
by Laurent Meunier 21 Nov '22

21 Nov '22

Hello, I would like to create rootful containers with static IPv4 and IPv6 addresses that are part of my network (containers that somehow act as physical devices on my network). From what I understand in the documentation [1], the macvlan driver should be my preferred option with netavark. [1] https://github.com/containers/podman/blob/main/docs/tutorials/basic_network… My problem is that I get an error when starting a container attached to a macvlan network created with an IPv6 subnet: > Error: netavark: failed configure macvlan: IO error: failed to add route: Invalid argument (os error 22) FYI, as long as the maclan network is created without IPv6 subnet, I can create new podman containers without error.

Installation of podman fails with access deniedon Windows
by Jochen Wiedmann 15 Nov '22

15 Nov '22

Hi, for your info, and for the record: having installed podman-desktop 0.9.1 on a Windows 10 machine, I couldn't initialize it, due to the error message mkdir C:\Users\jwi\.local\share\containers\podman: Access is denied. Workaround has been as follows: 1.) Execute the command podman machine init as a non-privileged user (myself) failed with the same error. 2.) Execute the command mkdir C:\Users\jwi\.local\share\containers\podman as a privileged user (Administrazor) worked. 3.) Repeating the "podman machine init" command as an unprivileged user works now, and Podman can be started. What's suprising for me: I would have expected, that I should be able to create a directory, that is located within my own home directory? Jochen -- Philosophy is useless, theology is worse.

systemd, podman play kube & restarting a pod automatically
by POIROTTE Francois 04 Nov '22

04 Nov '22

Hi, I'm working with a pod where 2 containers depend on one another. I'm using podman v4.3.0 and the pod is started using systemd (podman-kube@.service). When one of the containers is in an improper state (crashes, stops unexpectedly, or some other condition is not met), I would like to restart the whole pod automatically (just restarting the one container that stopped is not enough in my case). Ideally, systemd would be in charge of restarting the pod (using the Restart= directive to control precisely when it must be restarted). So far, I've tried using the healthchecks mechanism, but while podman correctly detects that the container is unhealthy, no further action is taken. Is there any way to achieve the desired result? Regards, François

Using Eclipse with Podman Engine on Linux
by Mehdi Haghgoo 02 Nov '22

02 Nov '22

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 01 Nov '22

01 Nov '22

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.

podman container storage backup
by Michael Ivanov 20 Oct '22

20 Oct '22

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 | ^ ^ | |
