kevinveenbirkenbachandClaude Opus 4.7 79409ebf10 test(tooling): integrate markdownlint-cli2, ansible-lint, galaxy-importer + fix the resulting baseline
Tooling integration
* add .markdownlint-cli2.jsonc, .ansible-lint, .ansible-lint-ignore
  configs (permissive day-1: cosmetic rules disabled, semantic ones on)
* extend scripts/install/lint.sh with generic install_pip_pkg helper +
  ensure_ansible_lint / ensure_galaxy_importer / ensure_markdownlint_cli2
  ensure_* functions (pip / npm with sudo / --user / --break-system-packages
  fallbacks). install_ansible_tools now also pulls ansible-lint and
  galaxy-importer; new `markdown` install group.
* extend scripts/lint/ansible.sh to run ansible-lint after the existing
  syntax-check.
* add scripts/lint/markdown.sh and scripts/lint/galaxy.sh runners. The
  galaxy runner parallelizes via xargs (-P=$(nproc)), prints OK/FAIL per
  role, and treats `bare-name dependency` errors as success since our
  roles/ tree is not a Galaxy collection layout. All other Galaxy schema
  errors still fail.
* Makefile: new lint-markdown and lint-galaxy targets, both wired into
  `make lint`.
* CI: new workflows lint-markdown.yml and lint-galaxy.yml; lint-ansible.yml
  now installs ansible-core + ansible-lint; ci-orchestrator wires both
  new lint workflows into lint-gate.

Galaxy schema fixes
* shorten the canonical `galaxy_info.company` block from three lines to
  two ("Kevin Veen-Birkenbach\nhttps://www.veen.world", 45 chars) so it
  stays under Galaxy's hard 50-char limit. Updated everywhere: 229 role
  meta/main.yml plus _CANONICAL_COMPANY in
  tests/lint/repository/test_role_meta_main_galaxy_schema.py.
* shorten 19 over-long role descriptions to <=255 chars.
* add stub READMEs for sys-svc-compose-ca and sys-utils-service-loader.

Markdown baseline fixes
* markdownlint-cli2 --fix run repo-wide (formatting normalization
  across CHANGELOG, role READMEs, docs).
* manual MD041 fixes: prepend H1 in 15 files (CHANGELOG, LICENSE,
  TODO.md helpers, role README templates, etc.).
* MD025 / MD003 / MD001 / MD032 manual fixes for heading-style and
  list-spacing edge cases.
* role README content polish: "## Single Point of Truth (SPOT)" headings
  renamed to "## User data resolution" (D3 self-label rule).

🧩 Ansible Plugins (plugins/)

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

🗂️ 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.
