What is Podman?

A container management tool…?!

Initially planned as debugging tool for the Kubernetes container runtime CRI-O

Now a feature-rich tool which can be used as a replacement for Docker

Traditionally, most Podman talks start with…

alias docker=podman

Getting started

pacman -S podman

Fedora / CentOS

dnf install podman

openSUSE Tumbleweed / Leap

zypper in podman

More packages available for:

Gentoo, macOS, RHEL, Ubuntu, Debian, Raspbian

Already built-in into

openSUSE Kubic, 

Fedora-CoreOS, Fedora SilverBlue
