YAML configration

It’s possible to store configuration data in external YAML files instead of Python code. The structure must follow the dictionary format though.

The previous Python configuration chapter describe the following YAML format:

config.yaml

---
inventory:
     plugin: SQLInventory
     options:
         sql_connection: 'mssql+pymssql://user:password@DBSERVER/DATABASE'
         hosts_query: >
             SELECT [CI name] AS name, hostname, groups
             FROM hosts
             WHERE status = 'deployed'
         groups_query: >
             SELECT name, platform
             FROM groups
             WHERE platform != ''
         defaults:
             username: 'my_user'
             password: 'my_password'
             connection_options:
                 scrapli:
                     platform: 'cisco_iosxe'
                     extras:
                         ssh_config_file: True
                         auth_strict_key: False

Then you can use this file by the initialization:

from nornir import InitNornir
nr = InitNornir(config_file="config.yaml")
