Creating Ansible Playbooks

Overview

Generate production-ready Ansible playbooks, roles, and inventories for infrastructure automation. Supports provisioning servers, deploying applications, configuring services, and enforcing desired state across fleets of machines using SSH-based agentless automation.

Prerequisites

• Ansible 2.14+ installed (ansible --version)
• SSH access to target hosts with key-based authentication
• Python 3.9+ on control node and managed nodes
• Inventory of target hosts (IPs or hostnames)
• Privilege escalation credentials (sudo) if configuring system-level resources
• ansible-lint installed for playbook validation

Instructions

1. Scan the project for existing Ansible files (ansible.cfg, inventory/, roles/, group_vars/) to understand current structure
2. Determine the automation target: server provisioning, application deployment, configuration management, or security hardening
3. Create the playbook YAML with proper structure: hosts, become, vars, tasks, handlers
4. Extract reusable logic into roles using the standard directory layout (tasks/, handlers/, templates/, defaults/, vars/, meta/)
5. Define variables in group_vars/ and host_vars/ for environment-specific values, keeping secrets in vault-encrypted files
6. Use Jinja2 templates for configuration files that vary across environments
7. Add handlers for service restarts triggered by configuration changes
8. Validate the playbook with ansible-lint and ansible-playbook --check --diff (dry run)
9. Test idempotency by running the playbook twice and confirming no changes on the second run
