kevinveenbirkenbachandClaude Opus 5.5 b83b361ea9 fix(web-app-bigbluebutton): run BBB v3.0.39 with the shared-notes server
The version-source update in #1146 moved the bigbluebutton/docker ref from
v3.0.23 to v3.0.39. That tag changes three things the role did not
handle, and it exposed a fourth defect in compose_file_args.

1. generate-compose renders etherpad and bbb-pads only behind
   USE_INSECURE_ETHERPAD and otherwise emits bbb-shared-notes-server with
   a `build:` block and no `image:` (upstream adds the image only after
   the tag, in 9a6a9a9a4c). compose_mods drops `build` only where an image
   is set, so the guard "Fail if any service still builds locally" stopped
   every BigBlueButton deploy (main run 39749899667, Nextcloud#11:
   `rc: 0`, `stdout: '    build:'`, bootstrap_compose_project.yml:35).
   meta/services.yml now pins alangecker/bbb-shared-notes-server:v3.0.39,
   compose_mods takes `pinned` (BBB_PINNED_SERVICES, every service the
   role config pins an image for) and drops their `build`, and the
   etherpad leftovers go (ep_redis_publisher patch, etherpad postgres
   entrypoint and initdb hook, etherpad database tasks, ETHERPAD_* env,
   etherpad_api_key secret).

2. The notes server connects to postgres once at start and exits with 2
   when it is not up yet; upstream gives it no restart policy. The
   override sets the role's restart policy, so it retries until postgres
   accepts connections.

3. Greenlight moves from v3.8.0 to v3.9.0.1, which sets
   `config.hosts = URL_HOST`, and the template passes
   `URL_HOST: https://${DOMAIN}`. Rails compares hostnames, so every
   request was blocked (`Blocked hosts: bbb.talk.infinito.test`, 403).
   Greenlight documents URL_HOST as the bare hostname; the override sets
   it to the role domain.

4. compose_file_args decided whether a role ships a compose override by
   templating "{{ application_id | abs_role_path_by_application_id }}"
   through the templar. ansible-core 2.21 does not render an untrusted
   string, so the check saw the literal and always returned False: the CA
   override generation and the pull handler never read BBB's
   compose.override.yml. That was harmless while compose.yml alone was
   valid; with the notes-server image living in the override, `compose
   config` failed ("has neither an image nor a build context"). The check
   now resolves the role path for the application id it is given. BBB is
   the only role that ships an override, so no other role's file list
   changes.

Existing installations drop the etherpad and bbb-pads containers on the
next `compose up --remove-orphans`; the old `etherpad` database stays in
PostgreSQL untouched.

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.
