Occasionally the question comes up on what puppet/cfengine/other integration looks like for Cobbler. So far that answer (for Puppet, anyway) has been to use external_nodes, as below, but I think we can do better than this. Here's the Wiki page on that:
https://fedorahosted.org/cobbler/wiki/UsingCobblerWithConfigManagementSystem How does this idea (to be explained below) sound for those that are using Puppet? I think this could be done with a minimum amount of code so it wouldn't be too intrusive to non-Puppet users. I don't think this was cleanly possible until 1.0, due to the new mod_python services infrastructure in Cobbler. New feature: Cobbler gets a new URL that serves up an external_nodes file for a given profile/system name. http://cobbler.example.org/cblr/svc/op/puppet/system/$name OR http://cobbler.example.org/cblr/svc/op/puppet/profile/$name This file returns the YAML file that is required to tell Puppet what puppet classes the node gets. Cobbler also ships a very simple snippet for use in kickstart %post that wgets this file when called, saves it, and uses that file to supply the answer to "external_nodes". We could source the variable assignments out of --ksmeta, so there would be no need for additional variables added into Cobbler to support this, just some added support code. For example: cobbler profile edit --name=webserver --ksmeta="profile=webserver" cobbler system edit --name=foo --profile="webserver" If it makes things easier we could still add a syntax like: cobbler profile edit --name=webserver --management-classes=webserver This feature would allow the profiles to be reassigned anytime, as needed, as the profile and system level without reinstalling the system. You can then manage your IP/MAC/install/config-mgmt associations all in one place, without having to hop between 6 or 7 different tools. To me, this is exactly what cobbler's goal is --- to allow you to do powerful edits in terms of "objects" and /what/ you want to get done, not how you want to do it. Thoughts? Does cfengine have a similar concept for mapping systems locally to the configuration rules they should access? --Michael _______________________________________________ cobbler mailing list [email protected] https://fedorahosted.org/mailman/listinfo/cobbler
