= MongoDB Sharding + Replica-sets Puppet Module =

== Global Variables ==

- Set to true to install the latest unstable binaries
$mongodb_unstable = false

- The config server port
$mongodb_configport = 20000

- The base shard-port. The actual port will be dependent on one of
- 1) replica-set names that inclues a number, ex: set1, set2, set3
- would become ports 10001, 10002, and 10003
- 2) the last octect of the ip-address, ex: 192.168.0.11 would
- set the shard port to 10011
$mongodb_shardport = 10000

- Prefix to all the mongodb dbpaths. For instance set to /data would
- create /data/config, /data/set1, /data/set2 etc...
$mongodb_prefix = "/var/lib/mongodb"

- Automatically setup simple sharding on databases, can be a db name
- or an array of db names
$mongodb_sharddb = ""

- Automatically setup simple sharding on collections, must be a hash
- with each key being the namespace (including DB), and the value being
- the sharding key for the collection
$mongodb_shards = {}

== Usage ==

include mongodb::config
include mongodb::router
mongodb::shard{["set1", "set2", "set3"]: replica => true }

If both a config server and router reside on the same machine, the config include should
happen before/in-front of the router include

Sharding can be customized with like:

mongodb::shard{ "set1": replica => true, priority => 2 }

Or for off-site backup-replicas:

mongodb::shard{ "set1": replica => true, priority => 0 }

Connection strings for applications can be built from the contents of /etc/mongorouter.conf
file which will exist on all shards, or can be including manually with:

collectfile{ "/etc/mongorouter.conf": }

== Requirements ==

* Puppet storeconfig=true
* Ubuntu (with up-start)
* global Exec{ path => "/bin:/usr/bin:/sbin:/usr/sbin" }
