2022-04-15

因为目前正在做autopkgtest的测试,所以这里得简短介绍下lxc的一些基本用法。

启动lxc

[email protected]:~# lxc-start -n autopkgtest-unstable-riscv64
[email protected]:~# lxc-ls -f
NAME                         STATE   AUTOSTART GROUPS IPV4      IPV6 UNPRIVILEGED
autopkgtest-unstable-riscv64 RUNNING 0         -      10.0.3.17 -    false

查看bridge

[email protected]:~# grep net /var/lib/lxc/autopkgtest-unstable-riscv64/config
lxc.net.0.type = veth
lxc.net.0.link = lxcbr0 # 在host上的bridge is lxcbr0

[email protected]:~# ifconfig lxcbr0
lxcbr0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.3.1  netmask 255.255.255.0  broadcast 10.0.3.255
        inet6 fe80::216:3eff:fe00:0  prefixlen 64  scopeid 0x20<link>
        ether 00:16:3e:00:00:00  txqueuelen 1000  (Ethernet)
