podman 介绍

使用 Podman 管理容器、Pod 和映像。从本地环境中无缝使用容器和 Kubernetes，Podman 提供与 Docker 非常相似的功能，它不需要在你的系统上运行任何守护进程，并且它也可以在没有 root 权限的情况下运行。

Podman 可以管理和运行任何符合 OCI（Open Container Initiative）规范的容器和容器镜像。Podman 提供了一个与 Docker 兼容的命令行前端来管理 Docker 镜像。

创建一键部署脚本

• 主要用于安装Podman容器引擎。脚本首先检查操作系统的版本，并根据不同的操作系统版本选择相应的安装方法。脚本支持CentOS、Red Hat、Oracle Linux、Rocky Linux、AlmaLinux、Ubuntu、Debian、Fedora和SUSE等多个发行版。
• 使用yum包管理器安装Podman及其插件，并配置registries.conf文件。对于Ubuntu和Debian，使用apt包管理器安装Podman及其插件，并配置registries.conf文件。对于Fedora，使用dnf包管理器安装Podman及其插件。对于SUSE，使用zypper包管理器安装Podman及其插件。
• podman --version | awk '{print $3}' #podman版本获取
• podman-compose --version 2>&1 | awk 'NR==1{print $3}' #podman-compose 版本获取
• podman-compose --version 2>&1 | head -n1 | awk '{print $NF}' #podman-compose 版本获取
• podman --help 命令使用参考
