Containers are increasingly making inroads into home networks. If you use Flatpaks or Snaps, you already use containers in everyday life. Future distributions will shed weight to a minimum, with required services running as containers of some kind. This development has been heralded by Fedora's Silverblue and Kinoite, Endless OS, MicroOS, and Intel's Clear Linux. It definitely makes sense for home users to consider the various container solutions.

Containers isolate applications through virtualization while providing a runtime environment. They make use of the filesystem and the resources of the operating system on which they run. This gives containerization the advantage of lower resource consumption compared with the traditional server approach or conventional virtualization. Where a virtual machine requires its own operating system, including a kernel, containers only store the actual applications plus any files and functions (microservices) required for execution.

Docker has long been synonymous with containers since its inception in 2013, but the advent of the Kubernetes container orchestration software has slowly started to change this perception. Recently, Podman [1] has been gaining momentum in the container sector, reaching version 4.0. After disputes between Docker and Red Hat over ongoing development, Red Hat began investing in Podman in 2017 as an application for managing containers and pods and has since cancelled support for Docker.
