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.
