Man, this has got to be an FAQ. I'm merrily scripting buildbot setup inside a container, and tried to do sudo lxc-start -n foo sh my-existing-setup-script.sh where my-existing-setup-script.sh does, among other things, sudo apt-get install python-dev (or, if the guest is running centos, some yum thing).
The first problem: apt-get hangs when it prompts the user for input. I worked around that by adding -y, but then found that the network is not up; sudo lxc-start -n foo -- ifconfig -a shows no IP addresses. So... I guess I have to actually start the system to run my script inside the container. I could use ssh to execute the command... but there's no easy way to find out what IP address to ssh to. lxc-start doesn't make the host show up in dns or the hosts file (should it?). I see lxc-start-ephemeral has about 70 lines of script to do just this: get the ip, wait for ssh to come up, and run a command via ssh. Is my easiest path to steal that code from lxc-start-ephemeral and create a command lxc-ssh that ssh's into a container given its name? Or does something like this already exist? I see http://www.stgraber.org/2012/07/17/easily-ssh-to-your-containers-and-vms-on-ubuntu-12-04-lts/ which claims to make ssh'ing in easy, but it solves a different problem. https://dev.launchpad.net/Running/LXC seems to indicate that the way to do this is install avahi-daemon inside the container, but I'd like to avoid relying on avahi. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
