vSphere Prerequisites and Resource Requirements

Page last updated:

This topic describes the prerequisites and resource requirements for installing Enterprise Pivotal Container Service (Enterprise PKS) on vSphere.

For prerequisites and resource requirements for installing Enterprise PKS on vSphere with NSX-T integration, see vSphere with NSX-T Version Requirements and Hardware Requirements for Enterprise PKS on vSphere with NSX-T.

Prerequisites

Before installing Enterprise PKS:

  1. Review the sections below and the instructions in Creating Dedicated Users and Roles for vSphere (Optional).

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

vSphere Version Requirements

For Enterprise PKS installations on vSphere, refer to the VMware Product Interoperability Matrices.

Resource Requirements

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

VM CPU RAM Storage
Pivotal Container Service 2 8 GB 16 GB ^*
Pivotal Ops Manager 1 8 GB 160 GB
BOSH Director 2 8 GB 16 GB

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 the Pivotal Container Service VM as follows:

Number of Pods Storage (Persistent Disk) Requirement ^*
1,000 pods 20 GB
5,000 pods 100 GB
10,000 pods 200 GB
50,000 pods 1,000 GB

Ephemeral VM Resources

Each Enterprise PKS deployment requires ephemeral VMs during installation and upgrades of Enterprise PKS. After you deploy Enterprise PKS, BOSH automatically deletes these VMs. To enable Enterprise PKS to dynamically create the ephemeral VMs when needed, ensure that the following resources are available in your vSphere infrastructure before deploying Enterprise PKS:
Ephemeral VM Number CPU Cores RAM Ephemeral Disk
BOSH Compilation VMs 4 4 4 GB 32 GB

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 Number CPU Cores RAM Ephemeral Disk Persistent Disk
master 1 or 3 2 4 GB 8 GB 5 GB
worker 1 or more 2 4 GB 8 GB 50 GB
errand (ephemeral) 1 1 1 GB 8 GB none

Network Communication Requirements

For a complete list of network communication requirements for vSphere without NSX-T, see Firewall Ports and Protocols Requirements for vSphere without NSX-T.
