Incus快速起步

Ubuntu 24.04 LTS以及后续版本都默认包含了 incus 软件包，可以非常轻松直接安装：

安装Incus
sudo apt update
sudo apt install incus -y

  • 将自己加入 incus-admin 组以便能够以普通用户身份来管理:

加入 incus-admin 组
sudo adduser $USER incus-admin
newgrp incus-admin

备注

incus有两个组:

  • incus 是普通的用户使用，不提供配置和限制到每个用户的项目操作

  • incus-adin 允许所有的控制操作

  • incus初始化:

初始化incus
$ sudo incus admin init
Would you like to use clustering? (yes/no) [default=no]: 
Do you want to configure a new storage pool? (yes/no) [default=yes]: 
Name of the new storage pool [default=default]: 
Name of the storage backend to use (lvm, lvmcluster, zfs, btrfs, dir) [default=zfs]: 
Create a new ZFS pool? (yes/no) [default=yes]: no
Name of the existing ZFS pool or dataset: incus-zpool
Would you like to create a new local network bridge? (yes/no) [default=yes]: 
What should the new bridge be called? [default=incusbr0]: 
What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
Would you like the server to be available over the network? (yes/no) [default=no]: 
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]: 
Would you like a YAML "init" preseed to be printed? (yes/no) [default=no]:

备注

这里使用了 Incus使用ZFS作为存储 实践构建的ZFS存储

运行debian 12容器
incus launch images:debian/12 debian12-dev

这里使用了 incus launch 表示下载、创建并直接启动容器(如果只想创建但不启动，可以使用 incus create )

image:debian/12 指定了官方镜像，这会下载最新的Debian 12(Bookworm)官方纯净系统镜像

debian12-dev 则是为容器起的名字

  • 检查容器状态:

检查容器状态
incus list

输出类似:

检查容器状态
+--------------+---------+----------------------+-----------------------------------------------+-----------+-----------+
|     NAME     |  STATE  |         IPV4         |                     IPV6                      |   TYPE    | SNAPSHOTS |
+--------------+---------+----------------------+-----------------------------------------------+-----------+-----------+
| debian12-dev | RUNNING | 10.108.19.229 (eth0) | fd42:77f7:87dd:98fc:216:3eff:feda:86a6 (eth0) | CONTAINER | 0         |
+--------------+---------+----------------------+-----------------------------------------------+-----------+-----------+

  • 进入容器(方法其实类似Docker)

执行进入容器
incus exec debian12-dev -- bash

此时可以看到位于 root@debian12-dev:~# 提示符下，表明已经进入了容器内部

  • 对于执行容器内命令，可以按照docker的方式来执行单条命令:

执行单条命令
incus exec debian-k8s-node1 -- apt update
