Virtual Appliance - System Requirements

Virtualization platform

The appliance is installed using an OVF (Open Virtualization Format) file and therefore requires a virtualization platform that supports OVF, such as VMWare ESXi.

Note

The appliance is not supported in public cloud environments.

Minimum CPU and memory requirements

Each virtual appliance VM requires:

  • 8 CPU Cores
  • 16 GB RAM
  • 100 GB disk space (SSD)

Fast storage

To ensure optimal performance and reliability, the use of a solid-state drive (SSD) or other fast storage solutions is required. Not using SSD based storage may lead to inconsistent behaviors and errors.

Fixed IP address

A fixed, non-changing IP address is required for each node. DHCP (Dynamic Host Configuration Protocol) is supported but the IP must be reserved and cannot change.

Network ports

The following ports must be exposed and available between all nodes:

Port Purpose
6443 Kubernetes API Server
8472 Virtual LAN
10250 Kubernetes metrics
2379-2380 etcd

The following port must be exposed internally for administrator access:

Port Purpose
9443 Appliance Administration Console

The following ports must be exposed for outside access:

Port Purpose
443 HACloud
3000 Security Proxy Server *
8001 AJP **

* The Security Proxy port use is optional.

** The AJP port is used when optionally integrated with Microsoft's IIS web server.

Supported web browsers
