May 2022 - Podman - Podman List Archives

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 | ^ ^ | |

GitHub Actions using podman?

by Craig Rodrigues

Hi, For Docker, there are a number of GitHub Actions with good documentation that can be used to build containers, and push them to registries using docker build/buildx. I've started using these Actions: https://github.com/docker/setup-buildx-action/ https://github.com/docker/docker-login-action/ https://github.com/docker/build-push-action https://github.com/docker/metadata-action docs: https://docs.github.com/en/actions/publishing-packages/publishing-docker-... These docs and actions are actually quite good when setting up automation in GitHub for building/pushing containers. Are there equivalent GitHub Actions for using podman? I still think that podman/buildah are overall better tools for building containers than Docker. -- Craig

How to clone a container?

by Clemens Eisserer

Hi, I have to use some non-well-made containers running a proprietary database product, where the data-directory can not be separated easily from the rest of the container. So modified state is not only stored at some specific paths, which I could re-direct to volumes, but spread over the whole file-system. Is there an easy way to backup such a container as a whole? I already tried to export the container to an image and later on re-import it, however it seems during this process some metadata is lost - when I try to start that re-imported container, podman complains about missing start script/commands. I already found podman clone, however on my system (fedora 35) it doesn't seem to be available. Are there maybe other ways to duplicate/export an existing container and keeping the clone in a working state? Thanks, Clemens

podman unhappy with usb device absent - ?

by lejeczek

Hi guys I get this, with I think is really weird and I hope somebody could shed more light on it. -> $ podman container restart wordpress.test.bits Error: crun: error stat'ing file `/dev/bus/usb/001/003`: No such file or directory: OCI runtime attempted to invoke a command that was not found There is only one USB I can guess is in play - an USB NIC but it has nothing to do with podman container nor its networks. But I also get this (different host from above): -> $ podman container restart wordpress.test.bits Error: crun: error stat'ing file `/dev/fb0`: No such file or directory: OCI runtime attempted to invoke a command that was not found What is podman/crun doing there & why? v 4.0.3 many thanks, L.
