Title:
Nova EC2 doesn't assign a floating IP to an instance being launched
Status in EC2 API:
New
Status in OpenStack Compute (Nova):
Confirmed
Bug description:
In EC2 classic mode AWS automatically associates a public IP address
to an instance being launched. See
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-instance-
addressing.html#differences
Since Nova EC2 emulates EC2 classic mode of AWS (there is no VPC
support in Nova EC2), it should associate a floating IP as well. But
it doesn't do this.
Though Nova has auto_assign_floating_ip parameter which does work
similar AWS. But it isn't implemented for Neutron networks. And it
affects both methods of running: EC2 and native Nova. Thus if we want
a cloud to be AWS compatible, and we use this parameter, we change
behavior of Nova in it's native part. This may be not desirable.
