Description

Set up Floating IPs with OpenStack

Make sure that nova is configured with the correct public network interface. The default is eth0, but you can change it in /etc/nova/nova.conf.

$> sudo bash -c 'echo "--public_interface=em1" >> /etc/nova/nova.conf'
$> sudo service openstack-nova-network restart

Carve out a block of addresses to use for instances:

$> sudo nova-manage floating create 10.0.0.224/28

Allocate an address to use for an instance:

$> euca-allocate-address 
ADDRESS	10.0.0.224

Associate the allocated address with a running instance:

$> euca-associate-address -i i-00000006 10.0.0.224
ADDRESS	10.0.0.224	i-00000006

Verify that you can now ssh into the instance using the newly assigned address:

$> cd ~/novacreds
$> ssh -i nova_key.priv root@10.0.0.224

If you would like, you can now disassociate and release the address assigned for testing.

$> euca-disassociate-address 10.0.0.224
ADDRESS	10.0.0.224
$> euca-release-address 10.0.0.224
ADDRESS	10.0.0.224
