Triggers Documentation? - cobbler - Fedora mailing-lists

28 Mar 2011


      Hello,
I would like to write a cobbler trigger to do something every time I add a 
system.  I looked at the documentation at:
     https://fedorahosted.org/cobbler/wiki/CobblerTriggers
but I think I am missing something.
A simple example is given in the form of a shell script and it shows $1 used 
as the name of a newly added system.  However, I see nothing defining the 
arguments passed, nor the environment.   I see that one can use the 
CobblerApi, but when I follow the link it tells me not to use "BootApi" (is 
BootApi == CobblerApi?) but to use "CobblerXmlrpc" instead.  That seems to be 
a client/server system.  The trigger docs say not to use it.
A says use B.  B says don't use B, use C.  A says don't use C. ????
So, is there anything defining the trigger API?
Does one really need to use Python to do anything meaningful?  I'm definitely 
not a Python wiz.
It says that pre-triggers can prevent an add operation.  How?  Just exit(1)?
How do I report errors back to the user?
In case it would help to understand my situation, I would like to be able to 
leave the networking empty and have a system add operation automatically 
define eth0 using the hostname to look up the MAC via "getent ethers 
hostname".  I can easily write the code to do the lookup in sh/bash/ksh or 
perl, but I need to be able to supply the information back to the cobbler 
system after the lookup. I need to be able to fail on errors.
