.. _rabbitmq-setup:

    :ref:`Cyclades Ganeti tools <cyclades-gtools>`, if you do not want to setup

    the Cyclades Network Service, but only the Cyclades Compute Service

    (recommended for now).

.. _cyclades-gtools:

Cyclades Ganeti tools

---------------------

In order for Ganeti to be connected with Cyclades later on, we need the

`Cyclades Ganeti tools` available on all Ganeti nodes (node1 & node2 in our

case). You can install them by running in both nodes:

.. code-block:: console

   # apt-get install snf-cyclades-gtools

This will install the following:

 * ``snf-ganeti-eventd`` (daemon to publish Ganeti related messages on RabbitMQ)

 * ``snf-ganeti-hook`` (all necessary hooks under ``/etc/ganeti/hooks``)

 * ``snf-progress-monitor`` (used by ``snf-image`` to publish progress messages)

 * ``kvm-vif-bridge`` (installed under ``/etc/ganeti`` to connect Ganeti with

   NFDHCPD)

Configure ``snf-cyclades-gtools``

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The package will install the ``/etc/synnefo/20-snf-cyclades-gtools.conf``

configuration file. At least we need to set the RabbitMQ endpoint for all tools

that need it:

.. code-block:: console

   RABBIT_HOST = "node1.example.com:5672"

   RABBIT_USERNAME = "synnefo"

   RABBIT_PASSWORD = "example_rabbitmq_passw0rd"

The above variables should reflect your :ref:`Message Queue setup

<rabbitmq-setup>`. This file should be editted in all Ganeti nodes.

Connect ``snf-image`` with ``snf-progress-monitor``

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Finally, we need to configure ``snf-image`` to publish progress messages during

the deployment of each Image. To do this, we edit ``/etc/default/snf-image`` and

set the corresponding variable to ``snf-progress-monitor``:

.. code-block:: console

   PROGRESS_MONITOR="snf-progress-monitor"

This file should be editted in all Ganeti nodes.

so we will call the user ``cyclades`` with password ``example_rapi_passw0rd``.

You can do this, by first running:

.. code-block:: console

   # echo -n 'cyclades:Ganeti Remote API:example_rapi_passw0rd' | openssl md5

and then putting the output in ``/var/lib/ganeti/rapi/users`` as follows:

   cyclades {HA1}55aec7050aa4e4b111ca43cb505a61a0 write
