# Wazuh Docker Deployment

## Deploying Wazuh Docker in a Single-Node Configuration

This deployment uses the `single-node/docker-compose.yml` file, which defines a setup with one Wazuh Manager, one Wazuh Indexer, and one Wazuh Dashboard container. Follow these steps to deploy it:

1.  Increase `vm.max_map_count` on each Docker host that will run a Wazuh Indexer container (Linux). This setting is crucial for Wazuh Indexer to operate correctly. This command requires root permissions:

    ```bash
    sudo sysctl -w vm.max_map_count=262144
    ```

    **Note:** This change is temporary and will revert upon reboot. To make it permanent, you'll need to edit the `/etc/sysctl.conf` file and add `vm.max_map_count=262144`, then apply with `sudo sysctl -p`.

2.  Navigate to the `single-node` directory within your repository:

    ```bash
    cd single-node
    ```

3.  Download the certificate creation script and `config.yml` file:

    ```bash
    curl -o wazuh-certs-tool.sh https://packages.wazuh.com/5.0/wazuh-certs-tool-5.0.0-1.sh
    curl -o config.yml https://packages.wazuh.com/5.0/config-5.0.0-1.yml
    ```

4.  Edit the config.yml file with the configuration of the Wazuh components to be deployed

    ```yaml
    nodes:
      # Wazuh indexer server nodes
      indexer:
        - name: wazuh.indexer
          dns: "wazuh.indexer"

      # Wazuh manager nodes
      # Use node_type only with more than one Wazuh manager
      manager:
        - name: wazuh.manager
          dns: "wazuh.manager"

      # Wazuh dashboard node
      dashboard:
        - name: wazuh.dashboard
          dns: "wazuh.dashboard"
    ```

5.  Run the certificate creation script:

    ```bash
    sudo bash ../tools/utils/deployment/certificates-conf.sh --cert --copy --priv
    ```

6.  Start the Wazuh environment using `docker compose`:

    * To run in the foreground (logs will be displayed in your current terminal; press `Ctrl+C` to stop):

        ```bash
        docker compose up
        ```

    * To run in the background (detached mode, allowing the containers to run independently of your terminal):

        ```bash
        docker compose up -d
        ```

Please allow some time for the environment to initialize, especially on the first run. It can take approximately a minute or two (depending on your host's resources) as the Wazuh Indexer starts up and generates the necessary indexes and index patterns.
