Soumplis' Personal Web Site
After a long time watching closely the evolution of Spacewalk (you know, the open source Redhat Satellite server), I decided to move on to its version 1.0. I have a working installation with more than 40 clients since version 0.2 and I followed all upgrades until version 0.8. At some time there I decided to wait for version 1.0 to move to a new server with adequate resources to handle the load. I must admit that I had a secret hope of not installing Oracle again.
I proceeded to the installation as per the spacewalk instructions and everything went smoothly. The I wanted to create my software channel. The plan is to create a Base channel of every CentOS and Redhat Update release and then have additional repos as child channels for each. This created a need for almost 20 channels with tens of clicks and repeated input. Ok, I can’t do it… I am not a Windows admin thus I hate anything that has to be completed with more than 2-3 clicks… Time for scripting!
I have downloaded the extended_create_channel.py from Spacewalk Wiki in order to use it in a simple bash script. For my disappointment it created channels without essential data such as the GPG keys and Yum Repositories information. It was high time for me to refresh my python to extend the script. The script is here and I believe is quite self explained.
