lxc.conf解析&lxc容器能力

lxd启动容器实际是生成lxc.conf。剩下的就是LXC对容器进行控制了。所以可认为lxc.conf就是lxd和lxc之间主要的接口。lxc.conf详细属性参考：

http://manpages.ubuntu.com/manpages/yakkety/en/man5/lxc.container.conf.5.html

本文对常用的部分属性做解释说明：

通过lxc.conf的了解可得如下能力：

 

lxc.conf的配置示例：

lxc.utsname = complex

lxc.network.type = veth

lxc.network.flags = up

lxc.network.link = br0

lxc.network.hwaddr = 4a:49:43:49:79:bf

lxc.network.ipv4 = 10.2.3.5/24 10.2.3.255

lxc.network.ipv6 = 2003:db8:1:0:214:1234:fe0b:3597

lxc.network.ipv6 = 2003:db8:1:0:214:5432:feab:3588

lxc.network.type = macvlan

lxc.network.flags = up

lxc.network.link = eth0

lxc.network.hwaddr = 4a:49:43:49:79:bd

lxc.network.ipv4 = 10.2.3.4/24

lxc.network.ipv4 = 192.168.10.125/24

lxc.network.ipv6 = 2003:db8:1:0:214:1234:fe0b:3596

lxc.network.type = phys

lxc.network.flags = up

lxc.network.link = dummy0

lxc.network.hwaddr = 4a:49:43:49:79:ff

lxc.network.ipv4 = 10.2.3.6/24

lxc.network.ipv6 = 2003:db8:1:0:214:1234:fe0b:3297

lxc.cgroup.cpuset.cpus = 0,1

lxc.cgroup.cpu.shares = 1234

lxc.cgroup.devices.deny = a

lxc.cgroup.devices.allow = c 1:3 rw

lxc.cgroup.devices.allow = b 8:0 rw

lxc.mount = /etc/fstab.complex

lxc.mount.entry = /lib /root/myrootfs/lib none ro,bind 0 0

lxc.rootfs = /mnt/rootfs.complex

lxc.cap.drop = sys_module mknod setuid net_raw

lxc.cap.drop = mac_override
