Prerequisites

Before deploying Wazuh on Docker, ensure your environment meets the following requirements.

System requirements

Additional configuration is required to ensure proper functionality when running Wazuh Docker on a Linux operating system.

Run the following command to set the max_map_count on your Docker host to 262,144. The Wazuh indexer creates a large number of memory‑mapped areas, so the kernel must be configured to allow at least 262,144 memory-mapped areas:
```
# sysctl -w vm.max_map_count=262144
```
Warning

If you don’t set a minimum value of at least 262,144 for max_map_count on your Linux host, the Wazuh indexer will not work correctly.
If you want to use Docker as a non-root user, you should add your user to the docker group using the following command:
```
# usermod -aG docker your-user
```
Log out and back in for changes to take effect.
If the command docker-compose fails after installation. Create a symbolic link to /usr/bin or any other directory in your path using the following command:
```
# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
```
