kevinveenbirkenbachandClaude Opus 5.5 474849a39c fix(svc-bkp-volume-2-local): read the baudolo version from pyproject.toml
Two bots bumped the one baudolo version independently. The pip pin
updater rewrites the literal package_name pin in
roles/svc-bkp-volume-2-local/tasks/01_install.yml and opens a PR scoped
to roles/<entry>/, and dependabot bumps the same package in
pyproject.toml. Each PR alone splits the pins that
tests/lint/repository/dependencies/test_baudolo_pin.py holds equal; #995
merged such a split and turned main's test-lint red until #996, and the
next upstream release (7.1.2 is tagged) would repeat it.

The version lookup now takes an optional distribution name and returns
its exact == pin from [project.dependencies]. The install task asks it
for backup-docker-to-local, so pyproject.toml is the only place the
version lives, dependabot is the only bot that moves it, and the pip
updater no longer finds a literal to bump. The lint now forbids a
literal pin in the task and requires the lookup.

Ansible Plugins (plugins/) 🧩

This document is the central reference for plugin types and plugin placement in Infinito.Nexus.

Not to be confused with application addons. This plugins/ directory holds Ansible plugins (action / filter / lookup) that extend the automation engine itself. Some applications also call their own extensions "plugins" (e.g. Nextcloud, WordPress). Those application-level extensions, whatever the app calls them natively, are declared through the unified meta/addons/ contract, documented in Unified Addons. An app "plugin" is an addon; an Ansible plugin lives here.

Current Project Layout 🗂️

plugins/
├── action/   # custom action plugins
├── filter/   # custom Jinja2 filters
└── lookup/   # custom lookup plugins

Configured plugin paths in this repository are defined in ansible.cfg:

  • action_plugins = ./plugins/action
  • filter_plugins = ./plugins/filter
  • lookup_plugins = ./plugins/lookup

All Common Ansible Plugin Types 📚

The table below summarizes common Ansible plugin types and their conventional directory names.

Emoji Plugin Type Conventional Directory Purpose
⚙️ action action_plugins/ or plugins/action/ Wrap/extend module execution behavior at task runtime.
🔐 become become_plugins/ Implement privilege escalation methods.
💾 cache cache_plugins/ Persist gathered facts and cached data between runs.
📣 callback callback_plugins/ React to play/task events (logging, reporting, notifications).
🖧 cliconf cliconf_plugins/ Define CLI command transport behavior (mainly network platforms).
🔌 connection connection_plugins/ Control how Ansible connects to targets (ssh, local, etc.).
🔍 filter filter_plugins/ or plugins/filter/ Add Jinja2 filters for data transformation.
🌐 httpapi httpapi_plugins/ API transport layer over HTTP(S), mainly for network devices.
🧭 inventory inventory_plugins/ Build dynamic inventories from APIs, services, or files.
👉 lookup lookup_plugins/ or plugins/lookup/ Resolve dynamic values during playbook processing.
🛰️ netconf netconf_plugins/ NETCONF transport integration for network automation.
🐚 shell shell_plugins/ Adjust shell command wrapping/execution behavior.
🧠 strategy strategy_plugins/ Customize task scheduling/execution strategy.
✅ test test_plugins/ Add Jinja2 tests used in conditions and templates.
📦 vars vars_plugins/ Load variables from custom sources.

Which Plugin Type to Use 🧭

action ⚙️

Use when task execution behavior itself must be changed or wrapped.

Examples:

  • centralized retry logic (uri_retry.py),
  • argument normalization before module dispatch,
  • pre/post task orchestration.

filter 🔍

Use for pure data transformation in Jinja2 expressions.

Examples:

  • mapping/normalizing dictionaries,
  • deriving computed fields for templates,
  • deterministic formatting helpers.

lookup 👉

Use when a value must be dynamically resolved at runtime.

Examples:

  • computing IDs from role metadata,
  • resolving paths/version data,
  • reading structured project data for templates/tasks.

callback 📣

Use to hook into execution events and shape output/reporting.

inventory 🧭

Use when host/group data should come from a dynamic source.

strategy 🧠

Use to alter how tasks are scheduled/executed across hosts.

vars 📦

Use to load variables from custom backends.

connection, become, shell 🔌🔐🐚

Use to customize low-level execution and privilege mechanics.

cache 💾

Use to persist facts/results across runs for performance and consistency.

cliconf, httpapi, netconf 🖧🌐🛰️

Use in network automation contexts requiring protocol-specific transport behavior.

test ✅

Use to add custom Jinja2 test operators for conditional logic.

Best Practices 🧪

  • Keep plugin interfaces explicit and stable.
  • Keep plugin logic focused; move shared logic to utils/.
  • Add unit tests for plugin behavior and integration tests for end-to-end flows.
  • Prefer deterministic outputs and avoid hidden global state.
  • Document any plugin-specific task arguments in the plugin docstring and README.
