Closing the Performance Gap: Automating Podman Benchmarks Across Linux, macOS, and Windows
Read more: Closing the Performance Gap: Automating Podman Benchmarks Across Linux, macOS, and Windows“It works on my machine” is a dangerous phrase in our line of work. While Podman runs natively on Linux, utilizing the kernel directly, the experience on macOS and Windows is different. These platforms require a virtual machine to provide the necessary Linux environment. This virtualization layer introduces overhead that often leads to user complaints…

Podman, Buildah, and Skopeo import paths
Read more: Podman, Buildah, and Skopeo import pathsSeveral of the containers projects are going to change their go import paths. Some of this work had been when we made the monorepo container-libs; where we moved storage, common, and image into a singular repository. The moves that are taking place now are not nearly as extreme and the motivations are also different. We…

Accelerating Parallel Layer Creation

Podman 6: machine usability improvements
Read more: Podman 6: machine usability improvementsI wanted to introduce a significant change we are making in Podman 6 for our machine function. To understand the problem and change, we first need to establish that Podman machine is based on a concept of providers. The provider is a generic term that describes how Podman runs the Linux virtual machine. The following…

Unlocking Speed: Accelerating Parallel Layer Removal in Podman v5.6
Read more: Unlocking Speed: Accelerating Parallel Layer Removal in Podman v5.6Container images are fundamentally structured as a series of read-only layers, with a writable layer typically added on top when a container instance is created. This layered architecture facilitates efficient storage and distribution by allowing multiple images to share common base layers. However, removing a layer, especially one that multiple images or containers might reference,…
