### Installing Wazuh Using Docker-Compose

Deploying Wazuh with Docker-Compose simplifies the installation and management process. Follow these steps to get Wazuh up and running.

#### Step-by-Step Docker-Compose Installation

1. **Install Docker and Docker-Compose**
    
    Ensure Docker and Docker-Compose are installed on your system. For installation instructions, refer to the <a rel="noreferrer" target="_new">Docker installation guide</a> and the <a rel="noreferrer" target="_new">Docker-Compose installation guide</a>.
2. **Create a Docker-Compose File**
    
    Create a directory for your Wazuh setup and navigate to it. Create a `docker-compose.yml` file with the following content:
    
    ```yaml
    services:
      wazuh:
        image: wazuh/wazuh:latest
        container_name: wazuh
        volumes:
          - wazuh-data:/var/ossec/data
        ports:
          - "1514:1514/udp"
          - "55000:55000"
        restart: unless-stopped
    
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:7.10.2
        container_name: elasticsearch
        environment:
          - discovery.type=single-node
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        volumes:
          - es-data:/usr/share/elasticsearch/data
        ports:
          - "9200:9200"
        restart: unless-stopped
    
      kibana:
        image: docker.elastic.co/kibana/kibana:7.10.2
        container_name: kibana
        environment:
          - ELASTICSEARCH_HOSTS=http://elasticsearch:9200
        ports:
          - "5601:5601"
        restart: unless-stopped
    
    volumes:
      wazuh-data:
      es-data:
    ```
3. **Start Wazuh**
    
    Open a terminal, navigate to the directory containing the `docker-compose.yml` file, and run the following command:
    
    ```bash
    docker-compose up -d
    ```
    
    This command will pull the Wazuh, Elasticsearch, and Kibana Docker images and start the containers in detached mode.
4. **Access the Wazuh Web UI**
    
    Open your web browser and navigate to `http://localhost:5601` to access the Kibana web interface, which serves as the frontend for Wazuh.
