Source: [github.com/redhat-cop/automation-good-practices](https://github.com/redhat-cop/automation-good-practices). + +## Guiding principles (Zen of Ansible) + +- Clear is better than cluttered. Concise is better than verbose. Simple is better than complex. Readability counts. +- Playbooks are not for programming; put logic in roles or custom modules. +- Declarative is better than imperative (most of the time). Convention over configuration. +- Helping users get things done matters most. User experience beats ideological purity. +- Every task should be idempotent; support check mode where possible. + +## Structures + +- **Landscape** → deploy at once (workflow or "playbook of playbooks"). +- **Type** → one per host; one playbook fully deploys that type. +- **Function** → implemented as a **role**; reusability. +- **Component** → task files inside a role (or separate component-roles if large); maintainability. + +Use roles for actual logic; keep playbooks as a list of roles. Avoid mixing `roles` and `tasks` (with include_role/import_role) in the same play—pick one style. + +## Roles + +### Design and naming + +- Design roles by **functionality**, not software implementation (e.g. "NTP configuration" role, not "chrony role"). +- **Variable naming**: prefix all defaults and role arguments with the role name (e.g. `foo_packages`, not `packages`). Internal (non-user) variables: prefix with two underscores, e.g. `__foo_variable`. +- **Tags**: prefix with role name or a unique descriptive prefix. +- **Role names**: no dashes (causes issues with collections); use underscores if needed. +- **Modules in roles**: prefix with role name, e.g. `foo_module`. +- Do not rely on host group names in roles; use a (list) variable or make the group name a role parameter. Set that variable at group level in inventory if needed. + +### Vars vs defaults + +- **defaults/main.yml**: every argument from outside the role gets a default here; document in README. Use for optional keys; no meaningful default → leave commented and let the role fail if undefined. +- **vars/main.yml**: static/magic values and large lists; do not use for user-overridable defaults (high precedence). +- Required packages → `vars/main.yml` as `foo_packages`; extra packages → `foo_extra_packages` in defaults (default `[]`). + +### Platform and provider + +- Avoid distribution/version checks in tasks. Use **vars per platform**: e.g. `vars/RedHat_8.yml`, `vars/Fedora.yml`, loaded via `include_vars` with `role_path` and a loop from least to most specific (`os_family`, `distribution`, `distribution_major_version`, `distribution_version`). Use `ansible_facts['distribution']` (bracket notation), not `ansible_distribution`. +- Multiple implementations (providers): input variable `$ROLENAME_provider`; if unset, detect current provider or choose by OS. Set `$ROLENAME_provider_os_default` for the default per OS. +- Platform-specific **tasks**: use `lookup('first_found')` with files from most to least specific, with a `default.yml` (or `skip: true`). Use `role_path` for paths. + +### Idempotency and check mode + +- Roles must be idempotent and report changes correctly (no fake changes on second run). For `command:` (or similar), set `changed_when:` explicitly. +- Support check mode when possible; document and justify if not. Use idempotent modules or `check_mode:`/`changed_when:`; avoid relying on registered vars from skipped non-idempotent tasks. + +### Files and templates + +- Use `{{ role_path }}/vars/...` and `{{ role_path }}/tasks/...` for includes with variable filenames so files are resolved within the role only. +- Templates: add `{{ ansible_managed | comment }}` at top; no "Last modified" dates (breaks idempotent change reporting). Prefer `backup: true` unless users need it configurable. +- Document clearly which config files the role **replaces** vs modifies. + +### Other role rules + +- Use Galaxy-compatible skeleton; semantic versioning for tags (0.y.z until stable). Use FQCN in examples (e.g. `kubernetes.core.k8s`, `ansible.posix.synchronize`). +- README: purpose, required/optional arguments, idempotent (Y/N), capabilities, example playbooks, rollback if applicable. +- Sub-task files: prefix task names with a short hint, e.g. `sub | Some task description`. +- From Ansible 2.11+: use `meta/argument_specs.yml` for role argument validation. + +## Coding style + +- **Naming**: `snake_case`; valid Python identifiers (no special chars in variables). Mnemonic names; avoid abbreviations or capitalize them. Name all tasks, plays, and blocks; task names in **imperative** ("Ensure service is running"). No numbering in role/playbook names. +- **YAML**: indent 2 spaces; indent list contents beyond the list marker. Use `.yml` extension. Use `true`/`false` for booleans (not `yes`/`no` or `True`/`False`). Spell out task arguments in YAML form (no `key=value`). Double quotes for YAML strings; single quotes for Jinja2 strings. No quotes for short keywords like `present`, `absent`. +- **Jinja2**: one space inside `{{ }}`, e.g. `{{ myvar }}`. Use bracket notation for keys: `item['key']`, not `item.key`. Use `| bool` for bare variables in `when:`. Long lines: use YAML folding `>-`; break long `when:` (and conditions) into a list. Prefer filter plugins over complex Jinja for data transformation. +- **Tasks**: prefer dedicated modules over `command`/`shell`; if using them, add a comment and ensure idempotency/check mode. Do not use `meta: end_play` (use `meta: end_host` if needed). Dynamic task names: put Jinja at the **end** of the name string (e.g. "Manage device {{ device }}"). Avoid variables in play names and in default loop variable in task names. +- **Debug**: set `verbosity:` on debug tasks so production logs stay clean. + +## Playbooks + +- Keep playbooks **simple**: ideally a list of roles (or a list of import_role/include_role tasks). Put logic in roles. +- Use either **roles** or **tasks** (with import_role/include_role), not both in the same play. +- **Tags**: use only (1) role-named tags to enable/disable roles, or (2) purpose-level tags that are safe to run alone. One tag should be enough for a meaningful outcome. Document tags. Never use tags that are unsafe or meaningless when used alone. + +## Collections + +- Structure at type or landscape level. Package roles in a collection for distribution and execution environments. +- Collection-wide variables: document them; reference in role defaults, e.g. `alpha_controller_username: "{{ mycollection_controller_username }}"`. Keep role variable naming (e.g. `alpha_*`) so roles stay reusable outside the collection. +- Include root README (purpose, license link, supported ansible-core versions, dependencies) and LICENSE or COPYING. + +## Inventories + +- **Single source of truth (SSOT)**: identify SSOTs (cloud/CMDB/inventory) and combine via dynamic inventory; keep only what is not provided elsewhere in static inventory. +- **As-Is vs To-Be**: keep discovered state (facts) separate from desired state (variables). Do not mix them. +- **Structure**: use an **inventory directory** with `group_vars/`, `host_vars/` (directories per group/host with one or more YAML files), and host/group lists. Avoid a single monolithic file when combining multiple sources. +- **Loop over hosts**: run plays against inventory groups and use host/group variables; do not maintain a separate list of hosts and loop over it. Use `--limit` and Ansible's parallelism instead of hand-written loops over host lists. + +## Inventories and variables (precedence) + +- Prefer **inventory variables** for desired state; avoid play/playbook variables and `include_vars` for that. Use extra vars for debugging/temporary overrides, not for defining desired state. +- Restrict variable types: prefer inventory vars and role defaults; use scoped (block/task) vars only when needed (e.g. loops, temporary values). + +## Plugins + +- Document all plugins (parameters, return values, examples). Use reST/Sphinx docstrings and Python type hints. Prefer **pytest** for unit tests. Keep plugin entry files small; move reusable logic to module_utils/ or plugin_utils/. Use ansible.plugin_builder for new plugins.
