How would I create a new ec2 instance, provision it and then destroy it all in the same play?
.. code-block:: yaml
# Use the ec2 module to create a new host and then add
# it to a special "ec2hosts" group.
- hosts: localhost
connection: local
gather_facts: False
vars:
ec2_access_key: "--REMOVED--"
ec2_secret_key: "--REMOVED--"

group: "mysecuritygroup"
region: "us-west-2"

ec2: image={{ image }}
instance_type={{ instance_type }}
aws_access_key={{ ec2_access_key }}

# Connect to the node and gather facts,

# it's state is "absent"
