butterknife 0.1.5

Butterknife makes bare-metal Linux deployment dead-simple using the Linux Containers (LXC) and Btrfs filesystem.

Install dependencies:

sudo apt-get install lxc python3-dev cython3 python3-pip pigz btrfs-progs
sudo pip3 install falcon click
sudo apt-get install python3-lxc # Ubuntu 14.04 or older

Place overlay/usr/bin/butterknife somewhere in PATH, eg /usr/bin and make it executable.

Listing templates

List local templates at /var/butterknife/pool:

butterknife list

List local templates in a particular directory:

butterknife list file:///path/to/directory

List templates at /var/butterknife/pool on a remote machine via SSH:

butterknife list ssh://hostname

List templates at remote machine via HTTP:

butterknife list http[s]://hostname[:port]

Pushing/pulling templates

Currently pull over SSH is working. Following replicates /var/butterknife/pool from machine hostname to local pool at /var/butterknife/pool:

butterknife pull ssh://hostname

Of course you can apply filters:

butterknife pull ssh://hostname --architecture x86 --namespace com.koodur.butterknife

You can also pull via HTTP:

butterknife pull http://butterknife.koodur.com

Note that symmetric push/pull requires patched btrfs-progs which has additional -p and -C flags for btrfs receive.

Multicast

Sending local template via multicast:

butterknife serve multicast @template\:com.koodur.butterknife.Ubuntu\:x86_64\:snap7

You can even multicast a remote subvolume:

butterknife serve multicast @template\:com.koodur.butterknife.Ubuntu\:x86_64\:snap7 --pool ssh://hostname

Receiving to local pool at /var/butterknife/pool:

butterknife multicast receive
