Data center requirements

This topic is for a deployment in a Data Center, not on a rented Cloud infrastructure, like AWS.

Deployment over Kubernetes requires an assessment of the data center and existing services. Below are the main services:

Mandatory:

• Kubernetes

• Object storage (S3)

• Managed Database (MySQL or Postgres)

Optional:

• DNS zone controller

• ELK or EFK (logging)

• Prometheus and Grafana (monitoring)

The deployment is performed using Helm Charts.

Examples of Kubernetes used in previous deployments: KubeSphere, EKS, OpenShift, K3S, and MiniCube (for testing).

Usual requirements

1. Kubernetes - preferred Opinshift 1.28

2. Object storage - S3 compatible, like MINIO

3. Database - preferred MySQL 5.7, minimum 2 cores, 16GB

4. Jump host (a separate VM) - 2 cores, 16GB

5. Configured DNS.

6. A pull of public IP addresses.

7. Mapping of public IP addresses/ports to local nodes IP addresses/ports,

8. Two load balancers.
