Private Mendix Platform Prerequisites

1 Introduction

This document presents the system requirements for the various parts of the Private Mendix Platform.

2 Hardware Requirements

For performance reasons, Mendix recommends at least the following minimum hardware requirements.

2.1 Kubernetes Hardware Requirements for Private Mendix Platform

Type	Min. Spec.
CPU	2 cores
Memory	4 GB
Database HA	CPU: 1 core; Memory: 2x2 GB

2.2 Kubernetes Hardware Requirements for an App Running on Private Mendix Platform

Type	Min. Spec.
CPU	1 core
Memory	2 GB
Database HA	CPU: 1 core; Memory: 2x2 GB

Additional services (Prometheus, Grafana, Loki) for observability are recommended.

3 General Requirements

• The machine where Private Mendix Platform is installed must have connectivity to the Container Registry and the Kubernetes cluster

• The cluster’s internal network policy must allow communication (from ingress) to services on the default port (8080).

• The Mendix Operator must be installed and fully configured:

  • The database plan must be created
  • The database server must be accessible from the Kubernetes cluster
  • The file storage plan must be created
  • The file storage server must be accessible from the Kubernetes cluster

• Mendix Studio Pro must be able to access Private Mendix Platform

• IdP for SSO must be available and configurable during installation process G* it, Jenkins and other services must be accessible on the same virtual network, or allow external bi-directional communication with Private Mendix Platform

• For Mendix Marketplace, a file server must be accessible over HTTP (or HTTPS) on either internal network or through a connection to a Mendix repository

• Private Mendix Platform should be able to access the Kubernetes API directly

4 Software Resource Requirements

Your Mendix app will be deployed with and run by the Mendix for Private Cloud Operator on top of Kubernetes. The following resources are required to facilitate this:

4.1 Platform Portal
