第 5 章：设置和管理映像¶
在本章中，您需要以非特权用户身份运行命令（如果您从一开始就遵循本书，则为“lxdadmin”）。
列出可用映像¶
您可能迫不及待地想开始使用容器。容器操作系统有很多种可能性。要了解有多少可能性，请输入以下命令
lxc image list images: | more
按空格键翻页浏览列表。这个容器和虚拟机列表会不断增长。
您最不希望做的事情是翻页寻找要安装的容器映像，尤其是在您知道要创建的映像的情况下。更改命令以仅显示 Rocky Linux 安装选项
lxc image list images: | grep rocky
这将显示一个更易于管理的列表

安装、重命名和列出映像¶
对于第一个容器，您将使用“rockylinux/8”。要安装它，您可能会使用
lxc launch images:rockylinux/8 rockylinux-test-8
这将创建一个名为“rockylinux-test-8”的基于 Rocky Linux 的容器。您可以在创建容器后重命名它，但首先需要停止容器，容器在创建时会自动启动。
要手动启动容器，请使用
lxc start rockylinux-test-8
要重命名映像（我们这里不会这样做，但这就是操作方法），首先停止容器
lxc stop rockylinux-test-8
使用move命令更改容器的名称
lxc move rockylinux-test-8 rockylinux-8
如果您按照此说明进行操作，请停止容器并将容器移回原始名称，以继续进行操作。
在本指南中，现在继续安装另外两个映像
lxc launch images:rockylinux/9 rockylinux-test-9
和
lxc launch images:ubuntu/22.04 ubuntu-test
通过列出您的映像来检查您拥有的内容
lxc list
这将返回以下内容
+-------------------+---------+----------------------+------+-----------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+-------------------+---------+----------------------+------+-----------+-----------+
| rockylinux-test-8 | RUNNING | 10.146.84.179 (eth0) | | CONTAINER | 0 |
+-------------------+---------+----------------------+------+-----------+-----------+
| rockylinux-test-9 | RUNNING | 10.146.84.180 (eth0) | | CONTAINER | 0 |
+-------------------+---------+----------------------+------+-----------+-----------+
| ubuntu-test | RUNNING | 10.146.84.181 (eth0) | | CONTAINER | 0 |
+-------------------+---------+----------------------+------+-----------+-----------+
