# Getting started with OpenNebula (one) Fog provider
|
|
|
|
[OpenNebula](http://www.opennebula.org) provides ruby bindings to access the xml-rpc
|
|
|
|
The opennebula fog extensions provides examples for using Fog with OpenNebula (4.4).
|
|
|
|
**Note:** This provider is under construction! This means everything that is provided should work without problems, but there are many features not available yet. Please contribute!
|
|
|
|
## Requirements
|
|
|
|
For working with this provider the following pre-requisites are needed:
|
|
|
|
* Ruby version 1.8.x or 1.9.x
|
|
* `fog` gem
|
|
* Working OpenNebula instance with XML-RPC and credentials
|
|
* This version is tested with OpenNebula 4.4 and the opennebula gem dependency is hardcoded to this version. it should work with version 4.6, but is not tested.
|
|
|
|
|
|
## Examples
|
|
|
|
General proceeding:
|
|
|
|
* Connect to one-rpc
|
|
* create new vm object
|
|
* fetch a template/flavor from one (this template should be predefined)
|
|
* assigne the flavor/template to the vm
|
|
* change the attributes of this flavor/template (name, cpu, memory, nics....)
|
|
* save/instantiate the vm
|
|
|
|
```ruby
|
|
require 'fog'
|
|
|
|
# connect to your one rpc
|
|
con = Fog::Compute.new(
|
|
{
|
|
:provider => 'OpenNebula',
|
|
:opennebula_username => 'user',
|
|
:opennebula_password => 'password',
|
|
:opennebula_endpoint => 'http://oned.domain:2633/RPC2'
|
|
}
|
|
)
|
|
|
|
|
|
# list all vms
|
|
con.servers
|
|
|
|
# list all flavors (templates in OpenNebula slang)
|
|
con.flavors
|
|
|
|
# get flavor with id 4
|
|
con.flavors.get 4
|
|
|
|
# list all Virtual Networks
|
|
con.networks
|
|
con.networks.get 2
|
|
|
|
# get all usergroups
|
|
con.groups
|
|
|
|
# create a new vm (creates the object, the vm is not instantiated yet)
|
|
newvm = con.servers.new
|
|
|
|
# set the flavor of the vm
|
|
newvm.flavor = con.flavors.get 4
|
|
|
|
# set the name of the vm
|
|
newvm.name = "FooBarVM"
|
|
|
|
# set the groupid of the vm
|
|
newvm.gid = 0
|
|
|
|
# set cores and memory (MB)
|
|
newvm.flavor.vcpu = 2
|
|
newvm.flavor.memory = 256
|
|
|
|
# create a new network interface attached to the network with id 1 and virtio as driver/model
|
|
network = client.networks.get(1)
|
|
nic = con.interfaces.new({ :vnet => network, :model => "virtio"})
|
|
|
|
# Attach the new nic to our vm
|
|
newvm.flavor.nic = [ nic ]
|
|
|
|
# instantiat the new vm
|
|
newvm.save
|
|
```
|
|

## Features
|

|
## not working yet
|
|
|
|
* con.groups.get 4
|
|
|
|
_AND_ everything not mentioned in features or examples ;)
|
|
|
|
|
|
## Troubleshooting
|
|
|
|
* ArgumentError: opennebula is not a recognized compute provider
|
|
* is the correct gem version included?
