Basic production template

The template defined below is meant for a typical production environment.

Use it to deploy RapidMiner AI Hub on Kubernetes, with the following components:

1 RapidMiner AI Hub instance
3 RapidMiner Job Agents
Postgres database
Platform Admin
1 JupyterHub instance
1 Dashboards instance
1 KeyCloak instance

For a detailed description of every Docker image, see the image reference.

System requirements

Minimum recommended hardware configuration

The amount of memory needed depends heavily on the amount of data that will be processed by RapidMiner AI Hub. By themselves, the RapidMiner services can run with as little as 8GB. However, in production environments, we recommend 32GB or more depending on user data, in order to provide users with enough capacity to analyze data from realistic use cases.

Each virtual or physical machine should at least have:

Quad core
32GB RAM
>20GB free disk space

Instructions

The provided Docker Images are ready to deploy to any Kubernetes Cluster.

Please review the configuration below according to your environment and requirements.

The following guide requires a running Kubernetes cluster.

Rapidminer Platform is supported on the following Kubernetes services:

Amazon Managed Kubernetes Service (Amazon EKS)
Azure Kubernetes Service (AKS)
MiniKube (Please read the Notices about minikube)
MicroK8S

Volumes

Volumes provides the Elastic Block Storage for the RapidMiner Platform components (Postgre DB, Python Enviroment Manager, RapidMiner Server, Real-Time Scoring) to store the data permanently during container life-cycle.

RapidMiner Proxy & Python Environment Manager

The proxy component handles the incoming HTTP(S) traffic into the entire platform. Python Environment manager component (PEM) controls the python packages for job-agents. Real-Time Scoring (RTS) was designed for fast scoring use cases via web services. Those three platform pieces are MUST in one POD in kubernetes beaucuse proxy must read the certificates which are genereated by pem-cron and rts-cron containers.
