Environment TestandClaude Sonnet 4.6 aa33256cde feat(mirror): split resolver output, move images to defaults, add lookup plugin
- resolver: output both applications: (config/main.yml compose images) and
  images: (defaults/main.yml images) keyed by source_file
- image_discovery: scan defaults/main.yml instead of vars/main.yml for images:
- mirror_overrides: write mirror URLs to applications.*.compose.services.*
  (mirror_policy-aware) and images_overrides.*.* (always merged, if_missing)
- roles/sys-ctl-hlth-csp, roles/test-e2e-playwright: move images: from
  vars/main.yml to defaults/main.yml for correct Ansible variable precedence
- plugins/lookup/image.py: new Ansible lookup plugin that prefers
  images_overrides over role-local images defaults
- docs: add artefact/image.md and artefact/mirror.md as SPOTs; add
  code/role/image.md contributor guide; link from ci.md
- tests: update test_util, test_mirror_overrides; add test_resolver,
  test_publish (404/401 coverage), test_image (lookup plugin)

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.
