Example reclass
===============

Setup MongoDB with database for ceilometer.

.. code-block:: yaml

     classes:
     - service.mongodb.server.cluster
     parameters:
        _param:
          mongodb_server_replica_set: ceilometer
          mongodb_ceilometer_password: cloudlab
          mongodb_admin_password: cloudlab
          mongodb_shared_key: xxx
        mongodb:
          server:
            database:
              ceilometer:
                enabled: true
                password: ${_param:mongodb_ceilometer_password}
                users:
                -  name: ceilometer
                   password: ${_param:mongodb_ceilometer_password}

Sample pillars
==============

Simple single server

.. code-block:: yaml

    mongodb:
      server:
        enabled: true
        bind:
          address: 0.0.0.0
          port: 27017
        admin:
          username: admin
          password: magicunicorn
        database:
          dbname:
            enabled: true
            encoding: 'utf8'
            users:
            - name: 'username'
              password: 'password'

Cluster of 3 nodes

.. code-block:: yaml

    mongodb:
      server:
        enabled: true
        logging:
          verbose: false
          logLevel: 1
          oplogLevel: 0
        admin:
          user: admin
          password: magicunicorn
        master: mongo01
        members:
          - host: 192.168.1.11
            priority: 2
          - host: 192.168.1.12
          - host: 192.168.1.13
        replica_set: default
        shared_key: magicunicorn

It's possible that first Salt run on master node won't pass correctly before
all slave nodes are up and ready.
Simply run salt again on master node to setup cluster, databases and users.

To check cluster status, execute following:

.. code-block:: bash

    mongo 127.0.0.1:27017/admin -u admin -p magicunicorn --eval "rs.status()"
