Custom Lookup Plugins for Infinito.Nexus
This directory contains custom Ansible lookup plugins used within the Infinito.Nexus project.
When to Use a Lookup Plugin
- Load external data: Use lookups to retrieve data from files, APIs, databases, environment variables, or other external sources.
- Context-aware data access: Lookups can access the full Ansible context, including inventory, facts, and runtime variables.
- Generate dynamic lists: Lookups are often used to build inventories, secrets, or host lists dynamically.
Examples
# Load the contents of a file as a variable
my_secret: "{{ lookup('file', '/path/to/secret.txt') }}"
# Retrieve a list of hostnames from an external source
host_list: "{{ lookup('infinito_inventory_hosts', 'group_name') }}"
When not to Use a Lookup Plugin
- If you only need to manipulate or transform data already available in your playbook, prefer a filter plugin instead.
