[lxc-users] Changing ip address

[BB]

Hi,

it depends on your template how address assigning is done (via DHCP,
statically, not at all, ...) but normally in the standard case the
containers get their IP addresses from the dnsmasq process that is running
on the containers' host system.

You can either...
1) Assign IP addresses yourself via the containers' config files, e.g.,
/var/lib/lxc/$CONTAINER_NAME/config by using the option lxc.network.ipv4  -
see "man lxc.container.conf, but you probably will have to set further
parameters to make this fully work
2) or you enable "LXC_DHCP_CONFILE=/etc/lxc/dnsmasq.conf"
in /etc/default/lxc-net and then assign IP addresses to hostnames
statically in /etc/lxc/dnsmasq.conf
3) or you statically set the particular IP address in the containers rootfs
- /etc/network/interfaces (at least for Debian/Ubuntu/...)

You probably should try the second option.

Kind regards,

BB
