I am trying to define a puppet setup for openvz and I need to check
the kernel version and all to make sure it''s right. Not clear now how
I check the current running version from facter''s $kernelrelease value
and if it doesn''t match - to reboot to said kernel... Anyone done
this?
Here''s what I got so far:
class openvz {
file { "/etc/sysconfig/selinux":
owner => "root",
mode => 644,
ensure => present,
contents => "SELINUX=disabled",
}
file { "/etc/yum.repos.d/openvz.repo":
owner => "root",
mode => 644,
ensure => present,
source => "puppet:///openvz/openvz.repo",
}
file {"/etc/sysctl.conf":
owner => "root",
mode => 644,
ensure => present,
source => "puppet:///openvz/sysctl.conf",
}
file {"/etc/modprobe.conf":
owner => "root",
mode => 644,
ensure => present,
}
line {"conn_track":
file => "/etc/modprobe.conf",
line => "options ip_conntrack ip_conntrack_enable_ve0=1",
}
package {"ovzkernel-2.6.18-53.1.19.el5.028stab053.14.x86_64":
ensure => installed,
provider => yum,
require =>
[File["/etc/sysconfig/selinux"],File["/etc/yum.repos.d/
openvz.repo"],File["/etc/sysctl.conf"],File["/etc/modprobe.conf"]],
}
package {"ovzkernel-devel-2.6.18-53.1.19.el5.028stab053.14.x86_64":
ensure => installed,
provider => yum,
require => Package["ovzkernel-
devel-2.6.18-53.1.19.el5.028stab053.14.x86_64"],
}
}

Anyone done > this?Completely guessing here, but I''d expect it could be done with something like: case $kernelversion { "2.6.18-53.1.19.el5.028stab053.14": { # Things that require openvz kernel } "default": { package { "preferred-kernel": ensure => present; } file { "/boot/grub/menu.lst": ensure => present, source => "puppet:///openvzmodule/menu.lst", require => Package["preferred-kernel"], notify => Exec["/usr/sbin/update-grub"]; } exec { "/usr/sbin/update-grub": notify => Exec["shutdown"]; } exec { "shutdown": command => "/sbin/shutdown -t10 -r now"; } } } So basically using case (http://reductivelabs.com/trac/puppet/wiki/LanguageTutorial#case) to decide whether to grab some packages and files, and then applying them in the order that you might do manually (install new kernel, install new grub file, update-grub, reboot). I don''t claim this is anywhere near perfect (I do think it''s at least a workable start), and you may throw your systems into a reboot loop every time puppet runs if it''s misconfigured, but that''s why you have test systems and single-user mode, I guess. -- Mike Renfro / R&D Engineer, Center for Manufacturing Research, 931 372-3601 / Tennessee Technological University --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
