r10k Configuration Module

This is the r10k setup module. It has a base class to configure r10k to synchronize dynamic environments. You can be simply used by declaring it:

class { 'r10k':
  remote => 'git@github.com:someuser/puppet.git',
}

This will configure /etc/r10k.yaml and install the r10k gem after installing ruby using the puppetlabs/ruby module. It also has a few helper classes that do some useful things. The following will add a prerun_command to puppet.conf.

include r10k::prerun_command

The concept here is that this is declared on the puppet master(s) that have been configured with r10k. This will cause r10k to synchronize before each puppet run. Any errors synchronizing will be logged to the standard puppet run.

Mcollective Support

An mcollective agent is included in this module which can be used to do on demand synchronization. This mcollective application and agent can be installed on all masters using the following class

include r10k::mcollective

Using mco you can then trigger mcollective to call r10k using

mco r10k synchronize

An example post-recieve hook is included in the files directory. This hook can automatically cause code to synchronize on your servers at time of push in git.

###Install mcollective support for post recieve hooks Install the mco command from the puppet enterprise installation directory i.e.

cd ~/puppet-enterprise-3.0.1-el-6-x86_64/packages/el-6-x86_64
sudo rpm -i pe-mcollective-client-2.2.4-2.pe.el6.noarch.rpm

Copy the peadmin mcollective configuration and private keys from the certificate authority (puppet master)

/var/lib/peadmin/.mcollective
/var/lib/peadmin/.mcollective.d/mcollective-public.pem
/var/lib/peadmin/.mcollective.d/peadmin-cacert.pem
/var/lib/peadmin/.mcollective.d/peadmin-cert.pem
/var/lib/peadmin/.mcollective.d/peadmin-private.pem
/var/lib/peadmin/.mcollective.d/peadmin-public.pem

Ensure you update the paths in ~/.mcollective when copying to new users whose name is not peadmin. Ideally mcollective will be used with more then just the peadmin user's certificate in the future. That said, if your git user does not have a home diretory, you can rename .mcollective as /etc/client.cfg and copy the certs to somewhere that is readable by the respective user.

/home/gitolite/.mcollective
/home/gitolite/.mcollective.d/mcollective-public.pem
/home/gitolite/.mcollective.d/peadmin-cacert.pem
/home/gitolite/.mcollective.d/peadmin-cert.pem
/home/gitolite/.mcollective.d/peadmin-private.pem
/home/gitolite/.mcollective.d/peadmin-public.pem

Note: PE2 only requires the .mcollective file as the default auth was psk ##Support
