kevinveenbirkenbachandClaude Opus 4.7 017f67cd53 feat(plugins): introduce database_query module + migrate all SQL query tasks
Replaces controller-side `community.postgresql.postgresql_query` /
`community.mysql.mysql_query` calls with a project-local `database_query`
Ansible module that wraps `container exec -i <container> <psql|mysql>`
and pipes SQL via stdin. The module routes via the DB container's own
network so the same task works identically in shared mode (central
`svc-db-*` container) and non-shared mode (per-role `<entity>-database`
container) — the `container` field of `lookup('database', …)` is
shared-aware and the module just reads it. SQL payloads come from a
file (`query_file:`, preferred) or as a raw string (`query:`, escape
hatch). `named_args:` substitutes `%(name)s` placeholders with engine-
appropriate escaping (postgres single-quote-doubling, mariadb backslash
escapes), so role tasks stop string-interpolating Jinja into SQL.

New backends extend the module's `_ENGINES` dispatch table; everything
else is engine-agnostic. The module ships at `plugins/modules/` (Ansible
collection-style layout) — the shebang lint test learned to recognise
that path as a valid module location alongside the existing per-role
`library/` layout.

Two lint tests enforce the convention:

* `tests/lint/ansible/modules/test_no_raw_db_query_module_usage.py`
  forbids `community.postgresql.postgresql_query` /
  `community.mysql.mysql_query` in role tasks. Opt out per-line with
  `# nocheck: database-query` (used by `svc-db-postgres/tasks/02_init.yml`
  where the role manages its own DB and the `database` lookup would be
  self-referential).
* `tests/lint/ansible/modules/test_no_raw_database_query_string.py`
  forbids inline `query:` on `database_query:` tasks. Opt out with
  `# nocheck: database-query-raw` (no opt-outs in the current tree —
  every SQL payload reaches the module through a `.sql` file under
  `files/sql/`).

Role migrations:

* `web-app-peertube` — 3 tasks migrated, 3 new `.sql` files,
  `templates/upsert-oidc-plugin.sql.j2` deleted in favour of
  `files/sql/upsert-oidc-plugin.sql` + `named_args:`.
* `web-app-openproject` — 3 tasks migrated, 3 new `.sql` files for
  the LDAP-auth-source check/update/insert chain.
* `web-app-odoo` — 33 tasks migrated, 9 new `.sql` files for the
  LDAP / admin / init-database flows; 17 pre-existing OIDC `.sql`
  files renamed snake_case → kebab-case and relocated from
  `files/oidc/` to `files/sql/oidc/` (via `git mv` so rename history
  stays intact).

Unit tests cover every dispatch-table entry, the named_args escaper
(strings, ints, floats, bools, None, single-quote and backslash
injection vectors), and the password-redactor that hides
PGPASSWORD/MYSQL_PWD assignments from the module's returned `cmd`
field.

PostgreSQL

Description

This Ansible role deploys and configures a PostgreSQL database in a Docker container using Docker Compose. It is designed to simplify database administration by automating the creation of networks, containers, and essential database tasks (such as database and user creation) for a secure and high-performance environment.

Overview

Built for environments that demand reliability and ease of management, this role:

  • Sets up a dedicated Docker network for PostgreSQL.
  • Deploys a PostgreSQL container with secure configurations and automated healthchecks.
  • Automates tasks like database creation, user setup, and privilege assignments to streamline your workflows.

Purpose

The purpose of this role is to provide an effortless way to deploy a PostgreSQL database via Docker. It minimizes manual interventions while ensuring that your database is configured securely and reliably for both production and development scenarios.

Features

  • Automated Deployment: Installs PostgreSQL with minimal manual steps.
  • Robust Administration: Automatically creates databases, users, and assigns privileges.
  • Enhanced Security: The service is bound to 127.0.0.1:5432, restricting access and enhancing security.
  • Seamless Docker Integration: Works harmoniously with Docker Compose and other roles in your infrastructure.
