在本教程中，我们将学习如何在Arch Linux/Manjaro上安装Podman。 Podman是用于创建和维护Linux容器的命令行工具。它是libpod库的一部分。 Podman是一个无守护程序的容器引擎，用于在Linux系统上开发，管理和运行OCIContainer。 Docker和Podman之间的主要区别是Podman中没有守护程序。

在Arch Linux/Manjaro上安装Podman

更新Arch/Manjaro系统。

sudo pacman -Syyu

更新所有软件包后，继续在Arch Linux/Manjaro上安装Podman。

sudo pacman -S podman

我们应该获得类似于以下的输出。
