…r and compute, and docs - Define production inventory with controller and compute groups - Add controller group_vars for Keystone, DB, Glance, and RabbitMQ configuration - Add compute group_vars with virt_type, controller reference, and Nova auth - Document inventory layout and variable purposes across groups
- Restructure site playbook to sequence controller, compute, and test VM stages - Remove redundant roles from controller playbook for compatibility with new site.yml - Update compute playbook for role-only execution - Align README usage examples with new site.yml and modular structure
… duplicates - Added flagged words (e.g. misconfigured, keypair, nova_compute) to accept.txt - Reviewed extended list of regex terms for redundancy - Verified no duplicate or overlapping patterns in spellcheck configuration
…pendencies - Replace hardcoded values with variables for hosts, passwords, and service URLs - Use community and OpenStack Ansible collections for database and service modules - Manage service lists via variables for easier enable/start tasks - Enhance configuration templates to reference variables consistently - Implement idempotent commands with proper error handling in tasks - Add or update README files to clearly document role purpose, variables, and requirements - Define Ansible collections in requirements.yml to handle external dependencies
