This is how I got something similar working in order to terminate
instances. You will need to change the state and I'm using the inventory
script as my hosts file. I'm sure it can be cleaned up. In this case, I'm
targeting ec2 instances with the Nginx_Server tag.
# Connect to the node and gather facts,
# including the instance-id. These facts
# are added to inventory hostvars for the
# duration of the playbook's execution
# Typical "provisioning" tasks would go in
# this playbook.
- hosts: tag_Name_Nginx_Server
gather_facts: True
user: root
sudo: True
tasks:
# fetch instance data from the metadata servers in ec2
- ec2_facts:
# show all known facts for this host
#- debug: var=hostvars[inventory_hostname]
# just show the instance-id
- debug: msg="{{
hostvars[inventory_hostname]['ansible_ec2_instance_id'] }}"
# Using the instanceid, call the ec2 module
# locally to remove the instance by declaring
# its state is "absent"
- hosts: tag_Name_Nginx_Server
gather_facts: True
connection: local
tasks:
- name: destroy all instances
ec2: state='absent'
instance_ids={{ item }}
wait=true
with_items: hostvars[inventory_hostname]['ansible_ec2_instance_id']
