Installation

pip install -r requirements.txt

Use

python fliatingip_handler.py -c floatingip_handler.config.example

Configuration

[Default]
debug = False

[RabbitMQ]
monitoring_queue_name = floatingip
rabbitmq_hosts = rabbitmq01,rabbitmq02,rabbitmq03
rabbitmq_port = 5672
user = guest
pass = guest

Options:

• debug: Enable or disable debug trace logs.
• monitoring_queue_name: RabbitMQ queue name to create and manage (auto_delete queue)

• rabbitmq_port: RabbitMQ port
• user: RabbitMQ user name
• pass: RabbitMQ password

Configure/Dev handler actions

By default, no action is configure to do either UP or DOWN floating IP. If you want to handler these actions you should modified the code. There are 2 functions on the top of script:

• callback_create_floating_ip: Handler function for floating IP association
• callback_delete_floating_ip: Handler function for floating IP disassociation

An example:

from httplib2 import Http
def callback_delete_floating_ip(data):
    """Callback function for floating ip disassociation"""
    h = Http()
    print " * Floating IP %s disassociated" % data['floating_ip_address']
    unregister = json.loads(urllib2.urlopen("http://10.10.10.10/release/ipv4address?ip_address="+data['floating_ip_address']).read())

Test

sh test.sh
