In the install/routes.py, the 'run_ansible' method call in the 'install' function has been updated to dynamically pass the 'service' name, resulting in a more flexible and adaptable code. Previously, it was hardcoded to run only the 'waf_service', which limited its usage.
The code for the WAF installation process has been refactored to improve error handling. The `service_mod.generate_waf_inv` function is now called with `service` instead of hardcoded service names, and error messages are now more descriptive. Additionally, the Ansible role file for WAF has been renamed from `waf.yml` to `waf_haproxy.yml` to better represent its role.
Additionally, import paths were corrected in the Python file 'app/routes/install/routes.py'. Error handling was improved in the 'install_service' function to return details of any encountered exceptions.
