In this repository you will find the containers to run:
## Description
* Wazuh manager: it runs the Wazuh manager, Wazuh API and Filebeat OSS
* Wazuh dashboard: provides a web user interface to browse through alert data and allows you to visualize the agents configuration and status.
* Wazuh indexer: Wazuh indexer container (working as a single-node cluster or as a multi-node cluster). **Be aware to increase the `vm.max_map_count` setting, as it's detailed in the [Wazuh documentation](https://documentation.wazuh.com/current/docker/wazuh-container.html#increase-max-map-count-on-your-host-linux).**
The `wazuh/wazuh-docker` repository provides resources to deploy the Wazuh cybersecurity platform using Docker containers. This setup enables easy installation and orchestration of the full Wazuh stack, including the Wazuh server, dashboard (based on OpenSearch Dashboards), and OpenSearch for indexing and search.
The folder `build-docker-images` contains a README explaining how to build the Wazuh images and the necessary assets.
The folder `indexer-certs-creator` contains a README explaining how to create the certificates creator tool and the necessary assets.
The folder `single-node` contains a README explaining how to run a Wazuh environment with one Wazuh manager, one Wazuh indexer, and one Wazuh dashboard.
The folder `multi-node` contains a README explaining how to run a Wazuh environment with two Wazuh managers, three Wazuh indexers, and one Wazuh dashboard.
## Capabilities
- Full deployment of the Wazuh stack using Docker.
- `docker compose` support for orchestration.
- Scalable architecture with multi-node support.
- Data persistence through configurable volumes.
- Ready-to-use configurations for production or testing environments.
## Branch Convention
- `main`: Developing and testing of new features.
- `X.Y.Z`: Version-specific branches (e.g., `4.12.2`, `4.11.0`, etc.).

### Setup SSL certificate
You can also explore internal documentation in the [`docs`](https://github.com/wazuh/wazuh-docker/tree/main/docs) folder of this repository.
Before starting the environment it is required to provide an SSL certificate (or just generate one self-signed).
## Get Involved
Documentation on how to provide these two can be found at [Wazuh Docker Documentation](https://documentation.wazuh.com/current/docker/wazuh-container.html#production-deployment).
