利用Podman导入rocky容器镜像并安装httpd
1. 使用yum安装podman
[root@Rocky ~]# yum install -y podman2.使用podman导入rockylinux镜像
[root@Rocky ~]# podman load -i rockylinux.tar命令说明
podman load -i {此处为镜像文件}
导入完成后可以通过如下命令查看已经导入到podman中的镜像。
[root@Rocky ~]# podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/rockylinux 9.3.20231119-minimal 89d486197fde 3 months ago 132 MB
[root@Rocky ~]#3.使用导入rockylinux镜像，的开启名为skills的容器，映射指定端口和文件夹。
使用命令创建容器
podman run -dt -v /dockerlinux:/etc -v /mnt:/mnt -p 8000:80 --name skills 89d486197fde命令说明如下
podman run -dt -v {本地目录}:{容器内目录} -v {本地目录}:{容器内目录} -p {本地端口}:{容器端口} --name {容器名称} {镜像ID}端口说明：当客户机在访问我们主机8000端口时，将会将流量转发至我们容器内的80端口中。实现客户机访问到容器内主机对外提供的服务。
镜像ID说明：镜像ID可通过
podman images查看 该命令返回的IMAGE ID即是对应的镜像ID目录说明：上述命令中，
dockerlinux文件目录需要提前先建立好。此后容器内的/etc目录下的文件将会映射到我们dockerlinux目录中，我们修改主机内dockerlinux文件夹内的文件时，容器主机内的文件也会一并同步修改,，方便我们配置容器内的配置文件。映射主机/mnt目录到容器主机的/mnt中的作用是为了配置容器内的软件源。主机已将光盘镜像挂载到
/mnt映射到容器中，容器就可以使用包管理器离线安装软件。
授予主机映射到容器目录下的目录权限
[root@Rocky ~]# chmod 755 -R /dockerlinux
[root@Rocky ~]# chmod 755 -R /mnt4.进入skills容器内的bash
使用如下命令进入
[root@Rocky ~]# podman exec -it skills bash
bash-5.1#在容器中执行
bash-5.1# microdnf退出容器终端
bash-5.1# exit
exit
[root@Rocky ~]#5.在主机dockerlinux中找到容器的yum源，配置yum软件源。
[root@Rocky yum.repos.d]# cat /dockerlinux/yum.repos.d/cdrom.repo
[cdrom]
name=cdrom
baseurl=file:///mnt/BaseOS
enable=1
gpgcheck=0
[AppStream]
name=AppStream
baseurl=file:///mnt/AppStream
enable=1
gpgcheck=0
[root@Rocky yum.repos.d]#6.容器中安装并配置httpd
回到容器内
podman exec -it skills bash在容器内安装httpd
bash-5.1# microdnf install httpd
(microdnf:6): GLib-CRITICAL **: 17:08:02.663: g_path_get_basename: assertion 'file_name != NULL' failed
