[Spacewalk-list] Kickstart parameters and values

[Kalchik, Jeffery]

Good morning, Zyrius (et al.)

You should be able to acquire the value of $http_server in any kickstart file or snippet, as long as it’s not in the middle of a #raw/#end raw tag set.  You might want to take a look in /var/lib/cobbler/snippets/download_config_files for a Spacewalk distributed snippet that uses $http_server.

The line of code below that used ACTIVATION_KEYS used $getVar to acquire the value of $redhat_management_key, or a default value.  This way, I know that ACTIVATION_KEY does have a value (whether or not is actually valid is left as an exercise for the student <grin>).  This line of code exists in a code snippet, for each major production channel here, referenced in the appropriate kickstart file (I use cobbler more directly than most.)  I don’t see any reason that you shouldn’t be able to use this technique within Spacewalk’s kickstart profiles and scripts.

All of my system provisioning starts down in cobbler, and I’m using the cobbler terminology above.  If you’re working within the Spacewalk web interface, you’ll be in the kickstart management section, working with kickstart profiles (equivalent of cobbler kickstart files,) and scripts (equivalent of cobbler snippets.)  After making your changes to the Spacewalk kickstart profiles and Spacewalk kickstart scripts, check the Spacewalk kickstart file to see what your actual kickstart file will be.

Edit: And there’s the trick……near the bottom of the Spacewalk kickstart script edit page, there’s a series of check boxes for nochroot, erroronfail, and Template.  You have to check the Template box to enable the cobbler macro/koan/cheetah/template system.  If not, you’ll have to hard code your values in the script, which is not what you want to do, apparently.

Hi Jeff,

I'm creating kickstart file with spacewalk kickstart wizard. Maybe you could advice where and what should i write to get value of $http_server or $redhat_management_server. I want to download some extra files from spacewalk master or proxies, but need to know from which server kickstart was called.

They seem to work for me.

Those are not shell variables, but koan/cheetah fields.  You can’t use them directly inside #raw/#end raw tags.  You can set them into shell variables, though.

From a code snippet:

export ACTIVATION_KEYS='$getVar("redhat_management_key","DEFAULT_KEY”)'

From the resulting kickstart:

export ACTIVATION_KEYS='SERVER_KEY'

Yes, I’ve changed the values.  I’ve been doing this for 5+ years.

Hello,
I'm creating kickstart file on spacewalk 2.3 and want to use value of $http_server or $redhat_management_server in post script section. It works in advanced options -> custom options, but not in post scripts. How can i get that value in post section  script?
