I run podman with intel mpi. But there is something wrong.

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?
