Hi Tzach
I usually approach instance termination by matching the instances with ec2
dynamic inventory, then add them to a group and terminate them in another
play targeted at the newly created group, based on their instance id (which
is automatically added as an inventory variable by the ec2 inventory
script).
Note that I specify gather_facts: false and do not reference the hostvars
dictionary. That way, Ansible does not attempt or need to reach the
instances via ssh before it is able to terminate them.
- name: Find sandbox instance(s) with matching name
hosts: tag_Name_Test
gather_facts: false
tasks:
- name: Create group
group_by: key=legacy
- hosts: legacy
connection: local
gather_facts: false
tasks:
- name: Terminate instance(s)
ec2:
instance_ids: "{{ ec2_id }}"
state: absent
Hope this helps.
Tom
