Additional comments

The folowing directory/file structure needs to be created for upgrade.json files at the same directory where the playbook is called.

- inventories
- files
   - {{ network_id }} i.e. fuji
      - vms
         - {{ chain_id }}
            - upgrade.json

Also, a new variable for the files_path is needed in the user configuration file as follows:

files_path: /path/to/files  i.e. /home/ubuntu/my_ansible/files

Almost there!

I just noticed that the right naming is chain upgrades and not updates. Would you mind renaming the variables for clarity?
