Overview

This module was built to install and configure r10k. It has a base class to configure r10k to synchronize dynamic environments. It also has a series of lateral scripts and tools that assist in general workflow, that will be seperated into their own modules into the future.

Module Description

This module is meant to manage the installation and configuration of r10k using multiple installation methods on multiple platforms.

Setup

Please refer to the official r10k docs for specific configuration patterns.

Prefix Example

Instead of passing a single remote, you can pass a puppet hash as the sources parameter. This allows you to configure r10k with prefix support. This often used when multiple teams use seperate repos, or if hiera and puppet are distributed across two repos.

class { 'r10k':
  sources => {
    'webteam' => {
      'remote'  => 'ssh://[email protected]/webteam/somerepo.git',
      'basedir' => "${::settings::confdir}/environments",
      'prefix'  => true,
    },
    'secteam' => {
      'remote'  => 'ssh://[email protected]/secteam/someotherrepo.git',
      'basedir' => '/some/other/basedir',
      'prefix'  => true,
    },
  },
}

Setup Requirements

r10k connects via ssh and does so silently in the background, this typically requires ssh keys to be deployed in advance of configuring r10k. This includes the known host ( public ) key of the respective git server, and the user running r10k's private key used to authenticate git/ssh during background runs.

Here is an example of deploying the ssh keys needed for r10k to connect to a repo called puppet/control on a gitlab server. This is helpful when you need to automatically deploy new masters

#https://docs.puppetlabs.com/references/latest/type.html#sshkey
sshkey { "your.internal.gitlab.server.com":
  ensure => present,
  type   => "ssh-rsa",
  target => "/root/.ssh/known_hosts",
  key    => "...+dffsfHQ=="
}

# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_deploy_key { 'add_deploy_key_to_puppet_control':
  ensure       => present,
  name         => $::fqdn,
  path         => '/root/.ssh/id_dsa.pub',
  token        => hiera('gitlab_api_token'),
  project_name => 'puppet/control',
  server_url   => 'http://your.internal.gitlab.server.com',
  provider     => 'gitlab',
}

A simple example of creating an ssh private key would use an exec to call yes y | ssh-keygen -t dsa -C "r10k" -f /root/.ssh/id_dsa -q -N ''. The example above shows using git_deploy_key which would deploy that key to the remote git server via its api. This is often required in the programtic creation of compile masters.

Given r10k will likely be downloading your modules, often on the first server it's run on, you will have to puppet apply this module to bootstrap this configuration and allow for ongoing management from there.

Beginning with r10k

The simplest example of using it would be to declare a single remote that would be written to r10k.yaml.

class { 'r10k':
  remote => '[email protected]:someuser/puppet.git',
}

This will configure /etc/r10k.yaml and install the r10k gem after installing ruby using the puppetlabs/ruby module.

It also supports installation via multiple providers, such as installation in the puppet_enterprise ruby stack in versions less than 3.8

Installing into the puppet enterprise ruby stack in PE 3.x

class { 'r10k':
  remote   => '[email protected]:someuser/puppet.git',
  provider => 'pe_gem',
}

Note: On Puppet Enterprise 3.8 and higher the package is not declared as 3.8 ships with an embdedded r10k gem installed via the PE packages. To install r10k on a PE 3.8+ non-master, set puppet_master to false for the main r10k class (e.g. to use r10k with Razor)

Installing into the Puppet Enterprise ruby stack in PE 2015.x

class { 'r10k':
  remote   => '[email protected]:someuser/puppet.git',
  provider => 'puppet_gem',
}

Note: It is recommended you migrate to using the pe_r10k module which is basically a clone of this modules features and file tickets for anything missing.

Usage

Installing using a proxy server

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 Note: You must have mcollective already configured for this tool to work, Puppet Enterprise users will automatically have mcollective configured. This class does not restart the mcollective or pe-mcollective server on the nodes to which it is applied, so you may need to restart mcollective for it to see the newly installed r10k agent.

include r10k::mcollective

Using mco you can then trigger mcollective to call r10k using

mco r10k synchronize

You can sync an individual environment using:

mco r10k deploy <environment>

Note: This implies -p

You can sync an individual module using:

mco r10k deploy_module <module>

If you are required to run r10k as a specific user, you can do so by passing the user parameter:

mco r10k synchronize user=r10k

To obtain the output of running the shell command, run the agent like this:

mco rpc r10k synchronize -v

An example post-receive hook is included in the files directory. This hook can automatically cause code to synchronize on your servers at time of push in git. More modern git systems use webhooks, for those see below.

###Install mcollective support for post receive 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 directory, 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

Removing the mcollective agent

class { 'r10k::mcollective':
  ensure => false,
}

This will remove the mcollective agent/application and ddl files from disk. This likely would be if you are migrating to Code managerin Puppet Enterprise.

Webhook Support

For version control systems that use web driven post-receive processes you can use the example webhook included in this module. This webhook currently only runs on Puppet Enterprise and uses mcollective to automatically synchronize your environment across multiple masters. The webhook must be configured on the respective "control" repository a master that has mco installed and can contact the other masters in your fleet.

Webhook Github Enterprise - Non Authenticated

This is an example of using the webhook without authentication. The git_webhook type will use the api token to add the webhook to the "control" repo that contains your puppetfile. This is typically useful when you want to automate the addtion of the webhook to the repo.

# Required unless you disable mcollective
include r10k::mcollective
# Internal webhooks often don't need authentication and ssl
# Change the url below if this is changed
class {'r10k::webhook::config':
  enable_ssl     => false,
  protected      => false,
}

class {'r10k::webhook':
  require => Class['r10k::webhook::config'],
}

# Add webhook to control repository ( the repo where the Puppetfile lives )
#
# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_webhook { 'web_post_receive_webhook' :
  ensure       => present,
  webhook_url  => 'http://master.of.masters:8088/payload',
  token        =>  hiera('github_api_token'),
  project_name => 'organization/control',
  server_url   => 'https://your.github.enterprise.com',
  provider     => 'github',
}


# Add webhook to module repo if we are tracking branch in Puppetfile i.e.
# mod 'module_name',
#  :git    => 'http://github.com/organization/puppet-module_name',
#  :branch => 'master'
# The module name is determined from the repo name , i.e. <puppet-><module_name>
# All characters with left and including any hyphen are removed i.e. <puppet->
#
# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_webhook { 'web_post_receive_webhook_for_module' :
  ensure       => present,
  webhook_url  => 'http://master.of.masters:8088/module',
  token        =>  hiera('github_api_token'),
  project_name => 'organization/puppet-module_name',
  server_url   => 'https://your.github.enterprise.com',
  provider     => 'github',
}

Webhook Github Example - Authenticated

This is an example of using the webhook with authentication The git_webhook type will use the api token to add the webhook to the "control" repo that contains your puppetfile. This is typically useful when you want to automate the addtion of the webhook to the repo.

# Required unless you disable mcollective
include r10k::mcollective

# External webhooks often need authentication and ssl and authentication
# Change the url below if this is changed

class {'r10k::webhook::config':
  enable_ssl => true,
  protected  => true,
  notify     => Service['webhook'],
}

class {'r10k::webhook':
  require => Class['r10k::webhook::config'],
}

# Add webhook to control repository ( the repo where the Puppetfile lives )
#
# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_webhook { 'web_post_receive_webhook' :
  ensure             => present,
  webhook_url        => 'https://puppet:[email protected]:8088/payload',
  token              =>  hiera('github_api_token'),
  project_name       => 'organization/control',
  server_url         => 'https://api.github.com',
  disable_ssl_verify => true,
  provider           => 'github',
}

# Add webhook to module repo if we are tracking branch in Puppetfile i.e.
# mod 'module_name',
#  :git    => 'http://github.com/organization/puppet-module_name',
#  :branch => 'master'
# The module name is determined from the repo name , i.e. <puppet-><module_name>
# All characters with left and including any hyphen are removed i.e. <puppet->
#
# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_webhook { 'web_post_receive_webhook_for_module' :
  ensure       => present,
  webhook_url  => 'https://puppet:[email protected]:8088/module',
  token        =>  hiera('github_api_token'),
  project_name => 'organization/puppet-module_name',
  server_url   => 'https://api.github.com',
  disable_ssl_verify => true,
  provider     => 'github',
}

GitHub Secret Support

GitHub webhooks allow the use of a secret value that gets hashed against the payload to pass a signature in the request X-Hub-Signature header. To support the secret with the webhook do the following type of configuration.

class { 'r10k::webhook::config':
  protected     => false,
  github_secret => 'THISISTHEGITHUBWEBHOOKSECRET',
}

class { 'r10k::webhook':
  require => Class['r10k::webhook::config'],
}

Webhook - remove webhook init script and config file.

Moving to Code manager, and removing webhook

class {'r10k::webhook::config':
  ensure => false,
}

class {'r10k::webhook':
  ensure => false,
}

Running without mcollective

If you have only a single master, you may want to have the webhook run r10k directly rather then as peadmin via mcollective. This requires you to run as the user that can perform r10k commands which is typically root. The peadmin certificate no longer is managed or required.

# Instead of running via mco, run r10k directly
class {'r10k::webhook::config':
  use_mcollective => false,
}

# The hook needs to run as root when not running using mcollective
# It will issue r10k deploy environment <branch_from_gitlab_payload> -p
# When git pushes happen.
class {'r10k::webhook':
  use_mcollective => false,
  user            => 'root',
  group           => '0',
  require         => Class['r10k::webhook::config'],
}

Webhook Prefix Example

The following is an example of declaring the webhook when r10k prefixing are enabled.

prefix_command.rb

This script is fed the github/gitlab payload in via stdin. This script is meant to return the prefix as its output. This is needed as the payload does not contain the r10k prefix. The simplest way to determine the prefix is to use the remote url in the payload and find the respective key in r10k.yaml. An example prefix command is located in this repo here. Note that you may need to modify this script depending on your remote configuration to use one of the various remote styles.

file {'/usr/local/bin/prefix_command.rb':
  ensure => file,
  mode   => '0755',
  owner  => 'root',
  group  => '0',
  source => 'puppet:///modules/r10k/prefix_command.rb',
}

# Required unless you disable mcollective
include r10k::mcollective

class {'r10k::webhook::config':
  prefix         => true,
  prefix_command => '/usr/local/bin/prefix_command.rb',
  require        => File['/usr/local/bin/prefix_command.rb'],
}

class {'r10k::webhook':
  require => Class['r10k::webhook::config'],
}
# Deploy this webhook to your local gitlab server for the puppet/control repo.
#
# Resource git_webhook is provided by https://forge.puppet.com/abrader/gms
git_webhook { 'web_post_receive_webhook' :
  ensure       => present,
  webhook_url  => 'https://puppet:[email protected]:8088/payload',
  token        =>  hiera('gitlab_api_token'),
  project_name => 'puppet/control',
  server_url   => 'http://your.internal.gitlab.com',
  provider     => 'gitlab',
}

Webhook FOSS support

Currently the webhook relies on existing certificates for its ssl configuration. See this following ticket for more information. Until then , its possible to re-use you existing FOSS mcollective certificates.

Here is an working example on Ubuntu 14.04.2 LTS

class { '::r10k::webhook::config':
  protected        => false,
  public_key_path  => '/etc/mcollective/server_public.pem',  # Mandatory for FOSS
  private_key_path => '/etc/mcollective/server_private.pem', # Mandatory for FOSS
  notify           => Service['webhook'],
}

class { '::r10k::webhook':
  user    => 'puppet',                                       # Mandatory for FOSS
  group   => 'puppet',                                       # Mandatory for FOSS
  require => Class['::r10k::webhook::config'],
}

Webhook Slack notifications

You can enable Slack notifications for the webhook. You will need a Slack webhook URL and the slack-notifier gem installed.

To get the Slack webhook URL you need to:

Go to https://slack.com/apps/A0F7XDUAZ-incoming-webhooks.
Choose your team, press Configure.
In configurations press Add configuration.
Choose channel, press Add Incoming WebHooks integration.

Then configure the webhook to add your Slack Webhook URL.

class { '::r10k::webhook::config':
  . . .
  slack_webhook  => 'http://slack.webhook/webhook', # mandatory for usage
  slack_channel  => '#channel', # defaults to #default
  slack_username => 'r10k', # the username to use
}

Triggering the webhook from curl

To aid in debugging, or to give you some hints as to how to trigger the webhook by unsupported systems, here's a curl command to trigger the webhook to deploy the 'production' environment:

curl -d '
  {
    "repository": {"name": "foo", "owner": {"login": "foo"}}, 
    "ref": "production"
  }' http://puppet-master.example:8088/payload

Reference

####Class: r10k This is the main public class to be declared , handingly installation and configuration declarations

Parameters within r10k:

`remote`

A string to be passed in as the source with a hardcode prefix of puppet

`sources`

A hash of all sources, this gets read out into the file as yaml. Must not be declared with remote

`cachedir`

A single string setting the r10k.yaml configuration value of the same name

`configfile`

A path to the configuration file to manage. Be aware Puppet Enterprise 4.0 and higher may conflict if you manage /etc/puppetlabs/puppet/r10k.yaml

`version`

A value passed to the package resource for managing the gem version

`modulepath`

Deprecated: for older configfile environments configuration of modulepath in puppet.conf

`manage_modulepath`

Deprecated: declare a resource for managing modulepath in Puppet.conf

`manage_ruby_dependency`

When using system ruby , options on how to declare

`r10k_basedir`

This module requires the puppetlabs-ruby module. In the event that your environment already includes the module with some customization, you can use the manage_ruby_dependency parameter to adjust how this module expresses that requirement. The supported values are include,declare, or ignore. The values' behavior is outlined below:

declare default This will explicitly declare the ruby module. Additional declarations of the ruby module will result in an inability to compile a catalog.
include This will simply include the ruby module. When combined with class ordering, this will permit the user to manage the instantiation of the ruby module elsewhere, potentially with non-standard parameter values.
ignore This will assume that ruby is handled via some other mechanism than a puppet module named ruby. It is left to the user to insure the requirement be met.

`package_name`

The name of the package to be installed via the provider

`provider`

The supported installation modes for this module

portage
yum
bundle
pe_gem
puppet_gem
gem
zypper

`gentoo_keywords`

See r10k::install::portage class for more information

`install_options`

Options to pass to the provider declaration

`mcollective`

Install mcollective application and agents. This does NOT configure mcollective automatically

`manage_configfile_symlink`

Manage a symlink to the configuration file, for systems installed in weird file system configurations

`git_settings`

This is the git: key in r10k, it accepts a hash that can be used to configure rugged support.

    $git_settings = {
      'provider'    => 'rugged',
      'private_key' => '/root/.ssh/id_rsa',
    }

    class {'r10k':
      remote       => '[email protected]:acidprime/puppet.git',
      git_settings => $git_settings,
    }

`forge_settings`

This is the forge: key in r10k, it accepts a hash that contains settings for downloading modules from the Puppet Forge.

    $forge_settings = {
      'proxy'   => 'https://proxy.example.com:3128',
      'baseurl' => 'https://forgeapi.puppetlabs.com',
    }

    class {'r10k':
      remote         => '[email protected]:acidprime/puppet.git',
      forge_settings => $forge_settings,
    }

`configfile_symlink`

boolean if to manage symlink

`include_prerun_command`

Deprecated: Add prerun_command to puppet.conf to run r10k when the agent on the master runs. Suggest instead declaring r10k::postrun_command as that will run after the agent runs which prevents r10k from stopping configuration management of masters from occuring as it does with prerun_commands

`include_postrun_command`

r10k::include_postrun_command: true

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 after each puppet run. Any errors synchronizing will be logged to the standard puppet run.

Limitations

The 4.1.x release deprecates support for:

Puppet 3
Ruby 1.9.3

These items are are planned for removal in v5.0.0.
