# README.md for nginx-www-redirect Role

## Overview
The `nginx-www-redirect` role is designed to automate the process of setting up redirects from `www.domain.tld` to `domain.tld` for all domains and subdomains configured within the `{{nginx_servers_directory}}` directory. This role dynamically identifies configuration files following the pattern `*domain.tld.conf` and creates corresponding redirection rules.

## Role Description
This role performs several key tasks:
1. **Find Configuration Files**: Locates all `.conf` files in the `{{nginx_servers_directory}}` directory that match the `*.*.conf` pattern, ensuring that only domain and subdomain configurations are selected.
   
2. **Filter Domain Names**: Processes each configuration file, extracting the domain names and removing both the `.conf` extension and the `{{nginx_servers_directory}}` path.

3. **Prepare Redirect Domain Mappings**: Transforms the filtered domain names into a source-target mapping format, where `source` is `www.domain.tld` and `target` is `domain.tld`.

4. **Include nginx-domain-redirect Role**: Applies the redirection configuration using the `nginx-domain-redirect` role with the dynamically generated domain mappings.

## Usage
To use this role, include it in your playbook and ensure that the `nginx-domain-redirect` role is available in your Ansible environment. No additional configuration is required as the role is designed to dynamically identify and process the domain configurations.

Example playbook:
```yaml
- hosts: web-servers
  roles:
    - nginx-www-redirect
```

## Requirements
- Ansible environment set up and configured to run roles.
- Access to the `{{nginx_servers_directory}}` directory on the target hosts.
- The `nginx-domain-redirect` role must be present and properly configured to handle the redirection mappings.

## Notes
- This role is designed to work in environments where domain and subdomain configurations follow the naming pattern `*domain.tld.conf`.
- It automatically excludes any configurations that begin with `www.`, preventing duplicate redirects.
