podman traceback with env var a=b=c
by Barry Scott 16 Jun '22

16 Jun '22

I ran a build that works with docker and hit a traceback with a simple fix. I symlinked docker and docker-compose to podman and podman-compose. There is env var that is of the form A=B=C which needs this patch to allow podman-compose to work: $ diff -u /usr/lib/python3.10/site-packages/podman_compose.py~ /usr/lib/python3.10/site-packages/podman_compose.py --- /usr/lib/python3.10/site-packages/podman_compose.py~ 2022-06-14 14:16:45.825406742 +0100 +++ /usr/lib/python3.10/site-packages/podman_compose.py 2022-06-14 14:16:45.825406742 +0100 @@ -1502,7 +1502,7 @@ if args.workdir: cnt["working_dir"] = args.workdir env = dict(cnt.get('environment', {})) if args.env: - additional_env_vars = dict(map(lambda each: each.split('='), args.env)) + additional_env_vars = dict(map(lambda each: each.split('=', 1), args.env)) env.update(additional_env_vars) cnt['environment'] = env if not args.service_ports: With this fix the build worked as expected. Let me know if you want this in a bugzilla. Barry

Re: Need help in creating a rootless container in podman
by Anton Peters 12 Jun '22

Now that is remarkable. The overlay subdir has a supposedly random unique number. Me and my colleagues get exactly the same as a SHA256 hash for a duplicate blob when trying to push an image to quay.io : Getting image source signatures Error: trying to reuse blob sha256:476579af086aee78cb12d88b08fd6b61a80a3f055cae293ec2d15a37dbe7b3f9 at destination: Requesting bearer token: invalid status code from registry 400 (Bad Request) This must be something deep in how container images are handled. I wonder what data generates this specific hash; maybe an empty data set? -- Anton Peters

oscap-podman as non root
by Ed Haynes 06 Jun '22

06 Jun '22

In RHEL9 I installed oscap-podman script as part of the openscap-utils package. I'd like to use this script to scan container images pulled by a non-root user but when running says I have to run as root - any idea why this is a hard dependency? If I do have to run script as root is there any way to pass non root podman image ID to the script?

GitHub Actions using podman?
by Craig Rodrigues 27 May '22

27 May '22

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-im… 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 13 May '22

13 May '22

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 10 May '22

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.
