Awesome, let's gooo! 🚀 Here's how you can create a **custom SonarQube Docker image** using a `Dockerfile`.

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### 🛠 1. **Create a Project Directory**

```bash
mkdir custom-sonarqube
cd custom-sonarqube
```

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### 📄 2. **Create a `Dockerfile`**

```Dockerfile
# Use the official SonarQube base image
FROM sonarqube:community

# Maintainer (optional)
LABEL maintainer="infocusm21@gmail.com"

# Optional: Copy custom configuration
# COPY sonar.properties /opt/sonarqube/conf/sonar.properties

# Optional: Copy custom plugins
# COPY ./plugins/*.jar /opt/sonarqube/extensions/plugins/

# Expose the default SonarQube port
EXPOSE 9000

# The base image's CMD is already configured properly, so no need to override

```

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### ⚙️ 3. (Optional) Add Custom Config or Plugins

You can customize further:

#### 🔧 sonar.properties (Optional Config File)
If you want to override settings like DB config, web port, etc.:

```bash
# sonar.properties (example)
sonar.web.port=9000
sonar.security.realm=LDAP
```

Then uncomment this line in your Dockerfile:

```Dockerfile
COPY sonar.properties /opt/sonarqube/conf/sonar.properties
```

#### 🔌 Add Plugins

If you have additional plugins (`.jar` files):

```bash
mkdir plugins
# Place .jar plugin files inside ./plugins/
```

Then use:

```Dockerfile
COPY ./plugins/*.jar /opt/sonarqube/extensions/plugins/
```

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### 🧱 4. **Build the Image**

```bash
docker build -t my-custom-sonarqube .
```

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### 🚀 5. **Run the Container**

```bash
docker run -d -p 9000:9000 --name sonarqube sonarqube:latest
```

Visit:  
📍 `http://localhost:9000`  
Default login is:  
- **Username**: `admin`  
- **Password**: `admin`

✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨✨

### 💾 (Optional) Persist Data Using Volumes

```bash
docker run -d -p 9000:9000 \
  -v sonarqube_data:/opt/sonarqube/data \
  -v sonarqube_extensions:/opt/sonarqube/extensions \
  --name sonarqube-container my-custom-sonarqube
```
