Single SPOT lookup `plugins/lookup/compose_volumes.py` absorbs the applications-lookup pipe step and auto-wires `DEPLOYMENT_MODE` plus the `storage` group var from the templating context. Callers only pass what genuinely varies per service (`application_id` and an optional `extra_volumes` dict). Behavior change (bug fix): the filter was always invoked with the default `deployment_mode='compose'` because no caller passed it explicitly, which silently skipped the swarm-NFS driver-opts injection path. The lookup reads `DEPLOYMENT_MODE` from globals, so swarm-NFS volumes now render the `driver: local` / `driver_opts: type: nfs` block correctly. Callers can still override via `deployment_mode=` / `storage=` kwargs when a template needs non-default rendering. Other coordinated changes: - 81 template call sites migrated from pipe form to lookup form (single-line and multi-line shapes). - `FilterModule` registration in plugins/filter/compose_volumes.py removed so the deprecated pipe form fails fast at render time. The underlying `compose_volumes()` function stays exported and is imported by the new lookup plus the existing 21-test filter unit test module. - 10 new lookup unit tests pin the contract (term shape, kwargs pass-through, auto-wiring, override precedence, error cases). - Integration test `test_compose_volumes_call_required.py` updated: asserts the new lookup form is present in every `compose.yml.j2` and adds a second test forbidding the deprecated pipe form anywhere under `roles/**/templates/`.

Custom Filter Plugins for Infinito.Nexus
This directory contains custom Ansible filter plugins used within the Infinito.Nexus project.
When to Use a Filter Plugin
- Transform values: Use filters to transform, extract, reformat, or compute values from existing variables or facts.
- Inline data manipulation: Filters are designed for inline use in Jinja2 expressions (in templates, tasks, vars, etc.).
- No external lookups: Filters only operate on data you explicitly pass to them and cannot access external files, the Ansible inventory, or runtime context.
Examples
{{ role_name | get_entity_name }}
{{ my_list | unique }}
{{ user_email | regex_replace('^(.+)@.*$', '\\1') }}
When not to Use a Filter Plugin
- If you need to load data from an external source (e.g., file, environment, API), use a lookup plugin instead.
- If your logic requires access to inventory, facts, or host-level information that is not passed as a parameter.
