ReleaseEngineering/PuppetAgain/Modules/config

This module handles retrieving and access of the site specific config values.

Summary

We handle config variables via puppets extlookup() function, which reads data from keys in csv files in a directory we specify, and in the order we specify. Missing files are not errors, but missing keys (when not specified with a default here) are. We do not specify any defaults in the extlookup() function at all.

The csv files are stored in the modules/extlookup/ dir of our whole repo (source). Our search order is as follows, first->last.

1. local-config.csv

   optional, preferably symlinked to an in-repo site specific config file (e.g. seamonkey-config.csv)

2. default-config.csv

   stored directly in puppet, and should contain reasonable defaults.

3. moco-config.csv, seamonkey-config.csv

   User-specific configuration (more can be added). These are generally linked to by local-config.csv.

4. supplied-config.csv

   optional lower precedence than local-config.csv, this can be used for automated creation of config. Within mozilla we use this to inject configuration from the puppet instance that builds our puppetmasters (don't think about that too hard!)

5. secrets.csv

   Necessarily not stored in hg as this file contains secrets (e.g. password hashes). For simplicity we have a secrets.csv.in file in this directory that can be copied over and have the secrets added.

Manifests

Config

Usage

in manifests

class foo {
  include config
  if ($config::builder_username == "")
     fail("bad settings")
  }
}

in templates (note use of empty namespace designation)

Username is <%= scope.lookupvar('::config::builder_username') %>

Variables

puppet_notif_email

The e-mail address or list to send errors of the puppet daemon to. (Defaults to dustin@mozilla.com)

puppet_server

The hostname of the puppet master we should connect to. Qualified or unqualified hostnames are acceptable. (Defaults to puppet)

puppet_servers

A list of all puppet servers, so clients can try other servers if puppet_server is down (Defaults to a one-element list containing the value of puppet_server)

data_server

The hostname of the data server (Defaults to the repos)

data_servers

A list of all data servers (Defaults to a one-element list containing data_server)

builder_username

The username for the build and test slaves (Defaults to cltbld)

nrpe_allowed_hosts

A comma-separated list of IPs from which NRPE should accept check requests (added in bug 733545)

relay_domains

The fqdn where your smarthost will send mail (added in bug 733536)

ganglia_config_class

The puppet class to use to configure ganglia, e.g., ganglia::config-moco

crl_sync_url

The URL of CRL PEM file distributed by the CA server used by puppet masters to invalidate revoked certificates.

puppet_again_repo

The repository from which the PuppetAgain source should be fetched by puppet masters

global_authorized_keys

Names for SSH keys (see the ssh module) that will be accepted for root and (where applicable) builder on all hosts. All names listed here must have corresponding keys in modules/ssh/manifests/keys.pp.

puppet_server_reports

The 'reports' parameter that should be configured on puppet masters

puppet_server_reporturl

The 'reporturl' parameter that should be configured on puppet masters

Config::Secrets

The Secrets module handles all the secret config options, for clarity. It is imported directly by the config module, for simplicity throughout.

Usage

in manifests

class foo {
  include ::config
  if ($::config::secrets::builder_password == "")
     fail("missing password")
  }
}

in strings (note use of empty namespace designation)

Hash is ${::config::secrets::builder_password}
