---

## 🚀 **Features**
- Automatically deploys **Let's Encrypt certificates** to Docker Compose setups.
- Supports both **single-domain certificates** and **one wildcard certificate** for all subdomains.
- **Copies certificates** to the target directory inside the container.
- Automatically **reloads or restarts Nginx services** when certificates are updated.
- **Configures and manages a `systemd` service** for automated certificate deployment.
- **Includes a `systemd` timer** for scheduled renewals.
- **Handles dependent services** like `alert-compose`.

---

## 🔧 **Tasks Overview**

### **1️⃣ Main Tasks**
1. **Add Deployment Script**  
   - Copies `srv-web-proxy-tls-deploy.sh` to the administrator scripts directory.
   
2. **Create Certificate Directory**  
   - Ensures `cert_mount_directory` exists with proper permissions.
   
3. **Configure `systemd` Service**  
   - Deploys a `systemd` service file for the deployment process.
   
4. **Include `gen-timer` Role**  
   - Schedules automatic certificate deployment using a `systemd` timer.

### **2️⃣ Handlers**
- **Restart Nginx Service**  
  - Restarts `srv-web-proxy-tls-deploy` whenever a certificate update occurs.

---

## **🔧 Deploying Certificates into Docker Containers**
The role **automates copying certificates** into Docker Compose setups.

### **1️⃣ Deployment Script (`srv-web-proxy-tls-deploy.sh`)**
This script:
- **Copies certificates** to the correct container directory.
- **Reloads Nginx** inside all running containers.
- **Restarts containers if needed**.

**Usage:**
```sh
sh srv-web-proxy-tls-deploy.sh primary_domain /path/to/docker/compose
```
