6.0 - Cleaning up Resources

Overview

  • It's beyond recommended to cleanup cloud resources to avoid incurring charges for unused resources.

  • Typically in this scenario, resources should be removed in the order of creation, each will require modules used to create them. Most of the time will be the same, with state: absent added instead of present

  • For any resources that need to be "found" before cleanup, modules of similar name with _info suffixed can be used e.g.:

    • ec2_instance_info
    • ec2_vpc_net_info
    • ec2_vpc_route_info

  • Further information can be found via the Ansible docs.

  • Example EC2 termination playbook:
- name: AWS EC2 Termination
  hosts: localhost
  gather_facts: false

  vars_files:
  - vars/info.yaml
  - vars/instance_ids.yaml

  tasks:
  - name: Terminate Instances
    hosts: localhost
    connection: local
    tasks:
    - name: Terminate instances that were previously launched
      ec2:
        state: 'absent'
        instance_ids: '{{ instance_ids }}'
