# ansible

Sets standards for Ansible playbooks: task naming rules, FQCN module paths, Ansible Vault secret separation, and validation via ansible-lint.

## What it does

This rule instructs the assistant to follow strict conventions when generating Ansible plays and tasks. Every task name must start with an action verb, capitalize the first letter, and omit trailing periods. Tasks must use fully qualified collection names (FQCN) such as `ansible.builtin`. Direct calls to `command` or `shell` are restricted because they break idempotency; they require `creates:` or `removes:` arguments when unavoidable.

Secret handling follows a strict separation pattern. When using Ansible Vault, the rule mandates creating two files inside `group_vars/<group>`: `vars` and an encrypted `vault` file. Sensitive keys go into `vault` with a `vault_` prefix, while `vars` references them through Jinja2 expressions. Privilege escalation via `become: true` stays restricted to task level unless every step in a play requires root access.

Styling rules enforce two-space indentation, multi-line mapping syntax, and single quotes for strings. Verification relies on `ansible-lint` and `yamllint`, alongside `ansible-playbook --syntax-check` and dry-run execution with `--check --diff`.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/ansible.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/ansible.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/ansible.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/ansible.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/ansible.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/ansible.instructions.md

## When to use it
- isolate sensitive variables using separate `vars` and encrypted `vault` files
- enforce fully qualified collection names such as `ansible.builtin`
- organize task attributes and play sections in a consistent order
- eliminate non-idempotent `shell` calls without execution guards

## Example prompts
- Write a task to restart the web service using ansible.builtin modules and explicit state.
- Organize database credentials for db_servers using separate vars and encrypted vault files.
- Check playbook syntax and remove shell commands that lack creates or removes parameters.

# Ansible Conventions and Best Practices

## General Instructions

- Use Ansible to configure and manage infrastructure.
- Use version control for your Ansible configurations.
- Keep things simple; only use advanced features when necessary
- Give every play, block, and task a concise but descriptive `name`
  - Start names with an action verb that indicates the operation being performed, such as "Install," "Configure," or "Copy"
  - Capitalize the first letter of the task name
  - Omit periods from the end of task names for brevity
  - Omit the role name from role tasks; Ansible will automatically display the role name when running a role
  - When including tasks from a separate file, you may include the filename in each task name to make tasks easier to locate (e.g., `<TASK_FILENAME> : <TASK_NAME>`)
- Use comments to provide additional context about **what**, **how**, and/or **why** something is being done
  - Don't include redundant comments
- Use dynamic inventory for cloud resources
  - Use tags to dynamically create groups based on environment, function, location, etc.
  - Use `group_vars` to set variables based on these attributes
- Use idempotent Ansible modules whenever possible; avoid `shell`, `command`, and `raw`, as they break idempotency
  - If you have to use `shell` or `command`, use the `creates:` or `removes:` parameter, where feasible, to prevent unnecessary execution
- Use [fully qualified collection names (FQCN)](https://docs.ansible.com/ansible/latest/reference_appendices/glossary.html#term-Fully-Qualified-Collection-Name-FQCN) to ensure the correct module or plugin is selected
  - Use the `ansible.builtin` collection for [builtin modules and plugins](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/index.html#plugin-index)
- Group related tasks together to improve readability and modularity
- For modules where `state` is optional, explicitly set `state: present` or `state: absent` to improve clarity and consistency
- Use the lowest privileges necessary to perform a task
  - Only set `become: true` at the play level or on an `include:` statement, if all included tasks require super user privileges; otherwise, specify `become: true` at the task level
  - Only set `become: true` on a task if it requires super user privileges

## Secret Management

- When using Ansible alone, store secrets using Ansible Vault
  - Use the following process to make it easy to find where vaulted variables are defined
    1. Create a `group_vars/` subdirectory named after the group
    2. Inside this subdirectory, create two files named `vars` and `vault`
    3. In the `vars` file, define all of the variables needed, including any sensitive ones
    4. Copy all of the sensitive variables over to the `vault` file and prefix these variables with `vault_`
    5. Adjust the variables in the `vars` file to point to the matching `vault_` variables using Jinja2 syntax: `db_password: "{{ vault_db_password }}"`
    6. Encrypt the `vault` file to protect its contents
    7. Use the variable name from the `vars` file in your playbooks
- When using other tools with Ansible (e.g., Terraform), store secrets in a third-party secrets management tool (e.g., Hashicorp Vault, AWS Secrets Manager, etc.)
