Re: [Puppet Users] randomize minute
I end up doing this:
http://projects.puppetlabs.com/projects/1/wiki/Writing_Your_Own_Functions
and works well, I was hoping not to have to write a function, but then realized
I need to get node's facter ipaddress, add the 4 of the octet and a % 60
and we are set :-)
but thanks for the tip, added to my bookmark :)

Did you perhaps want the fqdn_rand() function?
This gives a "static random" number based on the node's fqdn (not IP
like you asked for, but hopefully usable anyway).
I use it like this:
$minute1 = fqdn_rand(15)
$minute2 = 15+$minute1
$minute3 = 30+$minute1
$minute4 = 45+$minute1
cron { "run puppet":
command => $puppetrun,
user=> root,
minute => [ $minute1, $minute2, $minute3, $minute4 ],
require => File[$sysadmindir],
}
(from
https://gitorious.org/qtqa/sysadmin/blobs/master/puppet/modules/puppet/manifests/unix.pp
)
Only think I can't remember is if it returns an integer from 0 .. 14 or 0 .. 15

[Puppet Users] randomize minute
Hello
I.m trying to get a 'static random' base on a node's ip address and
use that number as the minute for a crontab
so each node will get a number between and 59
The things is the number is generated by the puppet master and so all
node get the same value...
my current code :
random_minute = generate('/usr/bin/env', 'bash', '-c', 'host `uname
-n` | head -1 | awk \'{ print $4 }\' | awk -F . \'{ printf("%d\n",
($1+$2+$3+$4)%60); }\'')
So Im a lost what do i need to do so 'generate' used the node's IP and
not puppetmaster...
Thanks!
