Sugar Labs Puppet infrastructure.

== ~~Recipes~~ ==

== Modules ==

~~There~~ are ~~two kinds of Puppet recipes:~~

Puppet modules configure particular services like [[Service/git|git.sugarlabs.org]] or MySQL but not tied to final configurations, they are being configured from [[#Master|puppetmaster]].

* Puppet modules that are abstracted from final usage on particular Sugar Labs sites,

All modules are collected as repositories in [http://git.sugarlabs.org/puppets puppets] Gitorious project. Modules might be created from scratch or mirrored from upstream, so, all modules that are used within Sugar Labs are stored in one place. Module repository might have followed branches:

* and recipes that composite modules and describe final configurations of Sugar Labs services.

=== ~~Final~~ configuration ~~===~~

== Master ==

Only puppetmaster keeps final configuration for all Sugar Labs services. It is being started on [[Machine/lightwave|security machine]] in private git repository.

~~Final recipes are stored on [[Machine/lightwave|puppetmaster host]] in private git~~ repository:

=== Private repository ===

* {{Code|/var/lib/puppet/etc/puppet.git}}

Git repository ~~has submodules to~~ all, used ~~on all puppetized hosts,~~ modules from [http://git.sugarlabs.org/puppets puppets] project. ~~All submodules are checked out to ''production'' branch~~.

=== Repository hierarchy ===

Git repository consists of:

* {{Code|modules/}}, all used modules from [http://git.sugarlabs.org/puppets puppets] project in form of submodules.

* {{Code|manifests/site.pp}}, main recipe which contain common settings and includes nodes.

* {{Code|manifests/roles/}}, recipes that describes final configuration for particular service.

* {{Code|manifests/nodes/}}, puppetized nodes, configuration for hosts that ask puppetmaster.

== Nodes ==

'~~'In progress''~~

Hosts that fetch configuration from the [[#Master|puppetmast]] need <code>puppet >= 2.6</code> package. If {{Code|puppet}} was installed from gems, it needs to be initially configured:

puppetmasterd --mkusers

Node's puppet agent might have optional configuration in {{Code|/etc/puppet/puppet.conf}}:

~~End~~-~~usage nodes. Configuration settings are tracked by local git repository only since contain private data.~~

[main]

runinterval = <fetch-configuration-in-every-n-seconds>

~~=== jita~~.~~sugarlabs~~.~~org ===~~

Every puppetized host should have particular node file in {{Code|manifests/nodes/<host-name>.pp}} on [[#Master|puppetmaster]].
