Problems with sysctl module

Support
#1

Hi,

I've installed Foreman 1.2 on a Oracle Linux 6.4-box successfully and I'm
now trying to hook up something to control the sysctl-file on some boxes.
I've tried every sysctl-module on forge.puppetlabs.com but I can't get them
to work in Foreman. Can someone explain to me how I can create or add
custom Puppet Class parameters to control, for instance, the parameter
vm.swappiness? I can't get sysctl to work in Foreman.

Kind regards,
Andreas

Hello Andreas,

I think this is more Puppet related question, you should maybe consider
re-sending this to Puppet users list.

First of all, you should start with getting this done via plain puppet
first. I recommend to try your module locally via simple puppet apply
command.

If that works, move one step further and try with puppet master and
puppet agent.

Once this is working, you can then connect your master daemon to Foreman
using a smart proxy. Then you can use the Import button in the Puppet
Classes page to import our class and override parameters.

And after you import these, you can work with your class in Foreman.

See here: Foreman :: Manual

Unfortunately we don't have Best practices chapters in our manual that
would describe how to do setups. We assume you have existing puppet
infrastructure, or at least experience with it. It would be good idea to
have some document describing these.

I expect that a sysctl module provides defined types or new resource
types, not classes. If so, these won't show up in Foreman as classes
you can add via the ENC. Instead, use them in your own Puppet classes
and add those classes via Foreman.

Good day.

Sorry for rising a dead thread but spending some time with foreman I
learned a few tricks. And I want to share it with public.

For this task I've used this module:
https://forge.puppetlabs.com/fiddyspence/sysctl

And create small foreman module which is called sysctl-wrapper and consist
of single class(file) sysctl-wrapper/manifests/init.pp:
class sysctl-wrapper (
$sysctlData = false,
) {
include sysctl

if $sysctlData != false {
    create_resources('sysctl', $sysctlData)
}

}

Next thing is to import it foreman and override $sysctlData variable with
yaml syntax.
Example:
net.ipv6.conf.all.disable_ipv6:
ensure: present
permanent: true
value: 1
net.ipv6.conf.default.disable_ipv6:
ensure: present
permanent: true
value: 1

Hope this will be useful to somebody.

Thanks,
Mikhail.

Lukas,

I will try those steps. Any suggestions how to get it in a hierarchy, the
same way Foreman uses Host Groups and such?

I am afraid I don't understand the question. Can you re-prase?
