Page last updated:

This topic describes the prerequisites and resource requirements for installing VMware Enterprise PKS on Microsoft Azure.

Prerequisites

Before installing Enterprise PKS:

  1. Review the sections below.

  2. Install and configure Ops Manager. To install Ops Manager, follow the instructions in Installing and Configuring Ops Manager on Azure.

Subscription Requirements

For Enterprise PKS and Kubernetes services to run correctly, you must have at least a standard subscription tier.

Resource Requirements

Installing Ops Manager and Enterprise PKS requires the following virtual machines (VMs):

VM CPU Memory (GB) Ephemeral Disk (GB)
BOSH Director 2 8 16
Ops Manager 1 8 120
PKS API 2 8 64
PKS Database 2 8 64

Storage Requirements for Large Numbers of Pods

If you expect the cluster workload to run a large number of pods continuously, then increase the size of persistent disk storage allocated to the PKS Database VM as follows:

Number of Pods Persistent Disk Requirements (GB)
1,000 pods 20
5,000 pods 100
10,000 pods 200
50,000 pods 1,000

Kubernetes Cluster Resources

Each Kubernetes cluster provisioned through Enterprise PKS deploys the VMs listed below. If you deploy more than one Kubernetes cluster, you must scale your allocated resources appropriately.

VM VM Count CPU Cores Memory (GB) Ephemeral Disk (GB) Persistent Disk (GB)
master 1 2 4 32 5
worker 1 2 4 32 50
