Yesterday, virt-bootstrap came to life. This tool aims at simplifying the creation of root file systems for use with libvirt's LXC container drivers. I started prototyping it a few months ago and Radostin Stoyanov wonderfully took it over during this year's Google Summer of Code.
For most users, this tool will just be used by virt-manager (since version 1.4.2). But it can be used directly from any script or command line.
The nice thing about virt-bootstrap is that will allow you to create
a root file system out of existing docker images, tarballs or virt-builder
templates. For example, the following command will get and unpack the official
openSUSE docker image in /tmp/foo.
$ virt-bootstrap docker://opensuse /tmp/foo
Virt-bootstrap offers options to:
- generate qcow2 image with backing chain instead of plain folder
- apply user / group ID mapping
- set the root password in the container
Enjoy easy containers creation with libvirt ecosystem, and have fun!
