Linux Containers

Some notes around building and managing Linux Containers.

Building LXC on Debian Wheezy

Get the latest from https://linuxcontainers.org/downloads/ and configure it:

$ ./configure --enable-doc --enable-capabilities --enable-bash

$ make

$ sudo make install

The installer will deploy libraries in /usr/local/lib. Make sure to have your LD_LIBRARY_PATH correctly set:

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

You can then verify the function enabled on your system using lxc-checkconfig:

$ sudo lxc-checkconfig
Kernel configuration not found at /proc/config.gz; searching...
