Installation of Cyclades (and Plankton) on node1
773
================================================
774

  
775
This section describes the installation of Cyclades. Cyclades is Synnefo's
776
Compute service. Plankton (the Image Registry service) will get installed
777
automatically along with Cyclades, because it is contained in the same Synnefo
778
component right now.

Cyclades (and Plankton) Prerequisites
776
=====================================
779 777

  
780 778
Before proceeding with the Cyclades (and Plankton) installation, make sure you
781 779
have successfully set up Astakos and Pithos+ first, because Cyclades depends
......
785 783
Besides Astakos and Pithos+, you will also need a number of additional working
786 784
prerequisites, before you start the Cyclades installation.

793 788

  
794 789
`Ganeti <http://code.google.com/p/ganeti/>`_ handles the low level VM management
795 790
for Cyclades, so Cyclades requires a working Ganeti installation at the backend.

Installation

````````````
845
~~~~~~~~~~~~
851 846
For :ref:`Cyclades <cyclades>` to be able to launch VMs from specified Images,
852 847
you need the :ref:`snf-image <snf-image>` OS Definition installed on *all*
853 848
VM-capable Ganeti nodes. This means we need :ref:`snf-image <snf-image>` on
......
882 877
snf-image-host to run successfully.
883 878

  
884 879
Configuration
885
`````````````
880
~~~~~~~~~~~~~
886 881
snf-image supports native access to Images stored on Pithos+. This means that
887 882
snf-image can talk directly to the Pithos+ backend, without the need of providing
888 883
a public URL. More details, are described in the next section. For now, the only

You can test that snf-image is successfully installed by running on the

Now that snf-image is installed successfully we need to provide it with some

1022
    You can bypass the networking sections and go straight to `FIXME`, if you do
1023
    not want to setup the Cyclades Network Service, but only the Cyclades Compute
1024
    Service (recommended for now).
1016
    You can bypass the networking sections and go straight to

    :ref:`RAPI user <rapi-user>`, if you do not want to setup the Cyclades

1028 1023

  
1029 1024
This part is deployment-specific and must be customized based on the specific
1030 1025
needs of the system administrator. However, to do so, the administrator needs

1065 1060

  
1066 1061
Currently, Ganeti does not support IP Pool management. However, we've been

actively in touch with the official Ganeti team, who are reviewing a relatively

`````````````````````````````
1081
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1087 1082

  
1088 1083
We talked about the two types of Network from the Cyclades perspective, from the
1089 1084
VMs perspective and from Ganeti's perspective. Finally, we need to talk about

The physical hosts' setup is out of the scope of this guide.

1119 1114

  
1120 1115
Once you have Ganeti with IP pool management up and running, you need to choose

1143 1138
At this point, Ganeti knows about your preferred network, it can manage the IP

So, we have setup the bridges/vlans on the physical hosts appropriately, we have

added the desired network to Ganeti, we have installed nfdhcpd and installed the

At the physical host's level, it is the administrator's responsibility to

configure the network appropriately, according to his/her needs (as for the

1270 1265
we will configure Cyclades to talk to those 20 pre-provisioned bridges.

1335 1330
If everything works as expected, then you have finished the Network Setup at the

Once you have a working Ganeti installation create a new RAPI user that will

As a last step before installing Cyclades, create a new RAPI user that will
1342 1339
have ``write`` access. Cyclades will use this user to issue commands to Ganeti,
1343 1340
so we will call the user ``cyclades``. You can do this, by editting the file
1344 1341
``/var/lib/ganeti/rapi/users`` and adding the line:

You have now finished with all needed Prerequisites for Cyclades (and
