how it works

ServiceNow -> Python

ServiceNow will trigger the logic.py script.
It will also need to cover rest-api credentials.
In my python code, as a demo, I have bas64 encoded them.

logic.py --template --protocol --application --suffix --volsize

Python -> AWX

Python script does following steps :

• Parse arguments
• Convert functional data into technical data
  • Get aggregate/cluster/svm (search and filter)
  • Get volume name (search and auto increment)
  • Assemble extravars
• Get AWX template
• Launch template
• Print output

Note : A function to get aggregates from AIQUM is included, but not used

AWX -> Ansible

In AWX you must :

• Create ontap credential type and credentials (will be passed to playbook)
• Get AWX Token (using api) (to use in python script)
• Create sourcecontrol credentials (for git repo)
• Create project (source = git) to this repo, using sourcecontrol creds
• Create template (source = project), choose its_cifs.yml
  • use dummy inventory (we target localhost and inventory is mandatory)
  • prompt for extravars
  • add ontap credentials (used in playbook)

Ansible

its_cifs.yml will call create_source_volume.yml and optionally (enable_mirror flag in python) create_destination_volume.yml
