# ComposePress  

ComposePress is a **Docker-based toolkit** designed to streamline WordPress upgrades using official images. It provides **pre-configured Docker Compose files**, Dockerfiles, and standardized procedures to make WordPress maintenance more predictable and reliable.

## 🚀 Project Configuration  

### **Project Name & WordPress Version**  
Define a **unique project name** and **WordPress version** in the `.env` file:  
```bash
COMPOSE_PROJECT_NAME=test
WORDPRESS_VERSION=6-fpm
```

## 📂 Configuration Files  

Two important Nginx configuration files are available in the project directory.  After editing, perform a restart:

./nginx.conf    # Manually customizable configuration
```

---

## 🚀 Usage  

### **Initialize a Project with a Unique `COMPOSE_PROJECT_NAME`; expects one word**  
Run the following script to generate the required files:  
```bash
./generate-compose-nginx.sh
```

## 🔄 Upgrade Process  

### **1️⃣ Stop Containers & Clean Up**  
```bash
docker compose down -v

# Optional: Remove external database & content volume (DANGER: Only do this if you have backups)
grep -E 'DB_VOLUME|CONTENT_VOLUME' .env | cut -d '=' -f2 | xargs -I {} sh -c 'docker volume rm {} 2>/dev/null; docker volume create {}'

# Optional: Remove WordPress Image
docker rmi $(grep IMAGE_WEB .env | cut -d '=' -f2)
```

### **2️⃣ Update WordPress Version**  
Modify the version in .env:  
```bash
WORDPRESS_VERSION=7-fpm
```

### **3️⃣ Build & Deploy**  
```bash
# Build custom WordPress image
docker compose -f docker-compose.first.yml build 

# Install or upgrade WordPress volume from custom image
docker compose -f docker-compose.first.yml up -d

# Stop WordPress container (but keep HTML volume)
docker compose -f docker-compose.first.yml down

# Start production environment
docker compose up -d
```

### **4️⃣ Migrate Content (Themes, Plugins)**  
```bash
# Copy new content to production
cp -a wp-content-new/* wp-content/

# Verify permissions on the wp-content directory
chmod -R [appropriate-permissions] wp-content/
```

### **5️⃣ Optional: Database Updates for web address change**  
```bash
# Inside the database container
apt-get update && \
    apt-get install -y mariadb-client && \
