+# MariaDB Ansible Role
+
+An Ansible role for installing and configuring MariaDB on Debian-based systems using the official MariaDB repositories.
+
+## Features
+
+- ✅ Official MariaDB repository setup
+- ✅ Flexible version management (major and minor versions)
+- ✅ Automatic upgrade capabilities
+- ✅ Idempotent operations
+- ✅ Support for MariaDB versions 10, 11, and 12
+- ✅ Proper service management during upgrades
+
+## Requirements
+
+- **Target OS**: Debian-based systems (Debian, Ubuntu)
+- **Ansible**: >= 2.8
+- **Privileges**: sudo/root access required
+
+## Role Variables
+
+### Required Variables
+None. The role works with sensible defaults.
+
+### Optional Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `mariadb_major_version` | `"12"` | Major version for repository setup (10, 11, or 12) |
+| `mariadb_minor_version` | `undefined` | Minor version for specific version install (e.g., "8" for 11.8.x) |
+| `mariadb_force_upgrade` | `false` | Force repository update and package upgrade |
+
+### Variable Details
+
+#### `mariadb_major_version`
+- **Type**: String
+- **Choices**: `"10"`, `"11"`, `"12"`
+- **Purpose**: Determines which MariaDB repository to configure
+
+#### `mariadb_minor_version`
+- **Type**: String (optional)
+- **Format**: Just the minor number (e.g., `"8"` for version 11.8.x)
+- **Purpose**: Installs specific minor version, gets latest patch automatically
+- **Behavior**: When undefined, installs the latest available version
+
+#### `mariadb_force_upgrade`
+- **Type**: Boolean
+- **Purpose**: Forces repository reconfiguration and package upgrades
+- **Use case**: Required when upgrading between major versions
+
+## Dependencies
+
+None.
+
+## Example Playbooks
+
+### Basic Installation (Latest MariaDB 12)
+
+```yaml
+- hosts: servers
+  roles:
+    - mariadb
+```
+
+### Install Specific Major Version
+
+```yaml
+- hosts: servers
+  roles:
+    - role: mariadb
+      vars:
+        mariadb_major_version: "11"
+```
+
+### Install Specific Minor Version
+
+```yaml
+- hosts: servers
+  roles:
+    - role: mariadb
+      vars:
+        mariadb_major_version: "11"
+        mariadb_minor_version: "8"  # Installs latest 11.8.x
+```
+
+### Upgrade MariaDB Version
+
+```yaml
+- hosts: servers
+  roles:
+    - role: mariadb
+      vars:
+        mariadb_major_version: "12"
+        mariadb_force_upgrade: true
+```
+
+## Usage Scenarios
+
+### Fresh Installation
+```yaml
+# Install latest MariaDB 12
+- role: mariadb
+
+# Install latest MariaDB 11
+- role: mariadb
+  vars:
+    mariadb_major_version: "11"
+
+# Install MariaDB 11.8.x (latest patch)
+- role: mariadb
+  vars:
+    mariadb_major_version: "11"
+    mariadb_minor_version: "8"
+```
+
+### Version Upgrades
+```yaml
+# Upgrade from MariaDB 11 to 12
+- role: mariadb
+  vars:
+    mariadb_major_version: "12"
+    mariadb_force_upgrade: true
+
+# Upgrade to specific minor version
+- role: mariadb
+  vars:
+    mariadb_major_version: "12"
+    mariadb_minor_version: "1"
+    mariadb_force_upgrade: true
+```
+
+## How It Works
+
+### Normal Installation Process
+1. Install prerequisites (curl, ca-certificates)
+2. Download and run official MariaDB repository setup script
+3. Update apt cache
+4. Install MariaDB packages
+5. Start and enable MariaDB service
+
+### Upgrade Process (`mariadb_force_upgrade: true`)
+1. Stop MariaDB service
+2. Remove existing repository configuration
+3. Setup new repository with target version
+4. Update apt cache
+5. Upgrade packages to new version
+6. Run `mysql_upgrade` for schema compatibility
+7. Restart MariaDB service
+
+### Version Resolution Logic
+- **Repository**: Uses major version only (e.g., `mariadb-11.rolling`)
+- **Packages**: 
+  - Without minor version: `mariadb-server` (latest available)
+  - With minor version: `mariadb-server=1:11.8*` (latest patch in minor series)
+

+```
+
+## Handlers
+
+The role includes handlers for MariaDB service management:
+- `restart mariadb`: Restarts the MariaDB service
+
+## Examples with Command Line
+
+### Install with specific version
+```bash
+ansible-playbook playbook.yml -e "mariadb_major_version=11"
+```
+
+### Upgrade to new version
+```bash
+ansible-playbook playbook.yml -e "mariadb_major_version=12 mariadb_force_upgrade=true"
+```
+
+### Install specific minor version
+```bash
+ansible-playbook playbook.yml -e "mariadb_major_version=11 mariadb_minor_version=8"
+```
+
+## Troubleshooting
+
+### Repository Issues
+If you encounter repository-related issues, try forcing a repository update:
+```yaml
+mariadb_force_upgrade: true
+```
+
+### Version Conflicts
+When upgrading between major versions, always use:
+```yaml
+mariadb_force_upgrade: true
+```
+
+### Service Issues
+The role automatically handles service management, but you can manually check:
+```bash
+systemctl status mariadb
+```
