Ubuntu Linux provisioning automation with Cobbler

Sponsored Link
Cobbler is a Linux  installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux  tasks so you do not have to hop between lots of various commands and applications when rolling out new systems, and, in some cases, changing existing ones.
With a simple series of commands, network installs can be configured for PXE, reinstallations, media-based net-installs, and virtualized installs (supporting Xen, qemu, KVM, and some variants of VMware). Cobbler uses a helper program called ‘koan' (which interacts with Cobbler) for reinstallation and virtualization support.

Cobbler is a small and lightweight application (about 15k lines of Python code). It tries to be extremely simple to use both for very small and very large installations --- as well as easy to work on, extend, and hack. It avoids being "enterprisey" (as in complicated) whenever possible, but is highly useful in all sorts of enterprises by having a lot of advanced features and doing small things to save a large amount of time in repeated tasks.

Cobbler can also optionally help with managing DHCP, DNS, and yum package mirroring infrastructure --- in this regard, it is a more generalized automation app, rather than just dealing specifically with installations. There is also a lightweight built-in configuration management system, as well as support for integrating with configuration management systems like Puppet. Cobbler has a command line interface, a web interface , and also several API access options. That sounds like a lot, but it's really pretty simple. New users may like to start with the web app after doing the initial setup steps on the command line (cobbler check; cobbler import) as it will give them a good idea of all of the features available. Advanced features don't have to be understood all at once, they can be incorporated over time as the need for them arises.

  1. Cobbler is now packaged in Ubuntu (starting with 11.04). Installing it should be as easy as:
    sudo apt-get install cobbler (or using any GUI package manager).
