In computing, Podman (pod manager) is an open source Open Container Initiative (OCI)-compliant [1] container management tool from Red Hat used for handling containers, images, volumes, and pods on the Linux operating system, [2] with support for Mac OS and Microsoft Windows via a virtual machine. [3] Based on the libpod library, it offers APIs for the lifecycle management of containers, pods, images, and volumes. The API is identical to the Docker API. [4] Podman Desktop provides an alternative to Docker Desktop. [5]

<span class="mw-page-title-main">Linux distribution</span> Operating system based on the Linux kernel

A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.

In computing, a solution stack or software stack is a set of software subsystems or components needed to create a complete platform such that no additional software is needed to support applications. Applications are said to "run on" or "run on top of" the resulting platform.

OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, called containers, zones, virtual private servers (OpenVZ), partitions, virtual environments (VEs), virtual kernels, or jails. Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container.
