[Lxc-users] Container name as DNS name

[Ben Butler-Cole]

I've been looking into this further and I think I've misunderstood how this
should work.

For some reason I thought that with the default lxcbr0 config the
containers name would resolve for it as a DNS name. That doesn't seem to be
the case.

I've tried the ubuntu template and also sshd (on Ubuntu 12.04). Following
https://help.ubuntu.com/12.04/serverguide/lxc.html, I did the following:

sudo lxc-create -t sshd -n ssh1
ssh-keygen -f id
sudo mkdir /var/lib/lxc/ssh1/rootfs/root/.ssh
sudo cp id.pub /var/lib/lxc/ssh1/rootfs/root/.ssh/authorized_keys
sudo lxc-start -n ssh1 -d
ssh -i id root at ssh1.

This doesn't work. "ssh1." doesn't resolve to the container's address.

Any clues what I might be doing wrong?

I could actually live perfectly happily with the IP address. But I can't
see any way to recover the IP address for a container that you've just
created other than greping syslog for dnsmasq logs (or accessing it via the
console, but I'm using LXC programatically).

Thanks
