Re: [lxc-users] LXD: modify IP of snapshot before starting
Thanks for the responses. The container IP (CentOS 7) is set via /etc/sysconfig/network-interfaces/ifcfg-eth0. I actually didn't use the copy command, and maybe that is what I should do in this case. We do a snapshot and then build a new container from the snapshot. The only time we do this is when the container is nearly the same as another one. (same processes for a different entity). In most cases, we build a new container from previously set templates. I will try the copy command as you suggest in this case. Thanks, Steven G. Spencer On Fri, Dec 7, 2018 at 10:31 PM Serge E.

Using raw.lxc, using dhcp config on the host, using /etc/network/interfaces or the like in the container's rootfs? How are you currently copying it? Are you using lxc copy --stateless?

You should have a template container which "never" online, from it you could create copies, edit them and start them as you pleased. > * Stop the original container > * create the new container with the snapshot > * modify the IP of the new container > * start the original container > If it isn't possible, I'll continue on as I've been doing. -- With best regards, Andrey Repin Friday, December 7, 2018 20:32:59 Sorry for my terrible english... ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
