在Ubuntu Linux serer上如何列出所有可用于安装在LXD镜像存储中的VM镜像？
是否可以使用lxc命令行列出lxd镜像？

lxd是系统范围的守护程序，而lxd是与lxd守护程序通信的命令行客户端。
因此，您需要使用lxc命令列出LXD存储中的镜像。

本教程将学习如何使用lxc列出LXD中的VM镜像。

如何在LXD中列出VM镜像

列出所有VM镜像语法为：

lxc image list images:

您可以使用grep命令或更多命令，如下所示：

lxc image list images: | more
lxc image list images: | grep -i 'debian'
lxc image list images: | grep -i 'opensuse'

您可以按如下所示应用过滤器，以仅显示Alpine Linux vm镜像：

lxc image list images: 'alpine'
lxc image list images: 'opensuse'

您现在可以按照以下方式创建VM：

lxc launch images:alpine/3.8/amd64 alpine-www
lxc launch images:centos/7/amd64 cenots-db
lxc launch images:opensuse/15.0/amd64 opensuse-15
lxc list

如何获得Linux发行版列表？

运行以下grep命令/egrep命令，awk命令和sed命令的组合：

lxc image list images: |\
awk -F'|' '{ print }' |\
sed '/^[[:space:]]*$/d' |\
awk -F'/' '{ print "/" }' | sort | uniq | egrep -v 'more|ALIAS'

执行以下命令：

lxc image help

Description:
  Manage images
 
  In LXD containers are created from images. Those images were themselves
  either generated from an existing container or downloaded from an image
  server.
 
  When using remote images, LXD will automatically cache images for you
  and remove them upon expiration.
 
  The image unique identifier is the hash (sha-256) of its representation
  as a compressed tar包 (or for split images, the concatenation of the
  metadata and rootfs tar包s).
 
  Images can be referenced by their full hash, shortest unique partial
  hash or alias name (if one is set).
 
Usage:
  lxc image [command]
 
Available Commands:
  alias       Manage image aliases
  copy        Copy images between servers
  delete      Delete images
  edit        Edit image properties
  export      Export and download images
  import      Import images into the image store
  info        Show useful information about images
  list        List images
  refresh     Refresh images
  show        Show image properties
 
Global Flags:
      --debug            Show all debug messages
      --force-local      Force using the local unix socket
  -h, --help             Print help
      --project string   Override the source project
  -q, --quiet            Don't show progress information
  -v, --verbose          Show all information messages
      --version          Print version number
 
Use "lxc image [command] --help" for more information about a command.
