Dear list, I'm a happy user of LXC using an Ubuntu 14.04 LTS host. So far, I've used a stock Ubuntu container template and installed some stuff in it.
Here is how I set it up, using unprivileged containers: $ lxc-create -n base -t download --bdev dir -- -d ubuntu -r trusty -a amd64 $ mount -o bind /dev/ ~/.local/share/lxc/base/rootfs/dev $ chroot ~/.local/share/lxc/base/rootfs/ # install some stuff ... $ umount ~/.local/share/lxc/base/rootfs/dev The ~/.config/lxc/default.conf looks like this: lxc.id_map = u 0 10000001 10000 lxc.id_map = g 0 10000001 10000 Note the absence of networking – it is crucial in my scenario that the running containers have no access to the Internet. After the setup is done my custom application just clones containers from that "base" container and throws them away afterwards (using the Python API). So ideally I only need to set up the "base" container once. But I'd now like to automate the creation of the "base" container. I was thinking of taking a stock Ubuntu template and augmenting it with the things I need, possibly on my local machine, and shipping it to the host afterwards. However, I have no idea how to do that. Is it possible to create a container locally and pack it up to be extracted somewhere else? Would that even be portable? If so, is there tooling for that? I use configuration management for everything else already; LXC so far is the only thing I haven't automated.
