# Hardware

We keep a [Marple Installation Guide](https://gitlab.com/marple-public/marple-installation/) on gitlab for self-managed teams. Please find an overview of the general hardware requirements below.

## **Common Requirements**

* **CPU**: 4 vCPUs
* **RAM**: 8 GB
* **Storage**: Minimum 20 GB (for data storage, exports, and logs)
* **Network**: 100 Mbit/s upload and equal or better download speed
* **Operating System**: Linux (x86 architecture; ARM is not supported)
* **Internet Access**: Required to pull Marple container images

## **For Kubernetes Deployment**

* **Cluster Setup**: A running Kubernetes cluster
* **Pods**: 1 pod with the above minimum specifications
* **Persistent Storage**: 20 GB volume for data and logs

## **For Docker Compose Deployment**

* **Host System**: Bare metal or virtual machine
* **PostgreSQL**: Required (either included in Docker Compose or an external database)
* **Environment Variables**: Configuration for storage paths, database connection, and deployment name

## **External PostgreSQL (Optional)**

Marple needs a Postgres database to work. 

If you are using Docker Compose, a second container with the database is included by default. If you are using Kubernetes, or you just want to run the Postgres separately, you will need to run a dedicated Postgres instance.

* **Recommended Version**: PostgreSQL 17
* **Minimum Resources**: 2 vCPUs + 4 GB RAM
* **Azure-Specific**: Ensure UUID\_OSSP extension is enabled

## **Security**

* HTTPS recommended (e.g., reverse proxy in front of Marple)
* VPN access preferred for additional security
* Assign a fixed domain name (e.g., `marple.yourcompany.com`) instead of a raw IP
