When running Podman as root, the default location for storage is /var/lib/containers/storage. Of course, users cannot use this directory when running as non root, so Podman creates the storage by default in $HOME/.local/share/containers.
I recently received a bug report about some huge container images not working correctly in Docker. So I suggested to the reporter that they try them with Podman. He responded that he saw the images with docker images, but did not see them with podman images.
I explained to him that the Docker image and container database are separate from the Podman image and container database. I told him he would have to pull the images into Podman. Then I decided to try a cool feature of Podman, where I could pull images directly out of the Docker daemon.
Podman wasn't designed to manage containers startup order, dependency checking or failed container recovery. In fact, this job can be done by external tools and this blog post describes how we can use the systemd initialization service to work with Podman containers.
If you've missed the news so far, CoreOS was acquired by Red Hat at the beginning of 2018. This also means some changes for Buildah and Podman.
Buildah and Podman were previously projects within Project Atomic which is going to be sunset in favor of an immutable host combination of Container Linux and Fedora Atomic Host: this combination is called Fedora CoreOS. We therefore welcome you to the new websites, buildah.io and podman.io where you will find news, announcements, and more around the respective projects.
To start it up, check out the new Blogs and Releases sections on the site.
You’ve learned of Podman and all it’s coolness for running OCI-based containers, but you need a solution that is repeatable and scripted. Rather than just executing Podman commands, you want a stable API to call into and not need to screen scrape the output.
We heard you and now provide a Python package, python3-podman. This package allows you to access the facilities of a Podman service with #nobigfatdaemons.
