LATEST VERSION: v1.3 - RELEASE NOTES
Pivotal Container Service v1.2

vSphere with NSX-T Prerequisites and Resource Requirements

Page last updated:

This topic describes the prerequisites and resource requirements for installing Pivotal Container Service (PKS) on vSphere with NSX-T integration.

For prerequisites and resource requirements for installing PKS on vSphere without NSX-T integration, see vSphere Prerequisites and Resource Requirements.

PKS supports air-gapped deployments on vSphere with or without NSX-T integration.

You can also configure integration with the Harbor tile, an enterprise-class registry server for container images. For more information, see VMware Harbor Registry in the Pivotal Partner documentation.

Prerequisites

Resource Requirements

PKS

Installing Ops Manager and 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

Each PKS deployment requires ephemeral VMs during installation and upgrades of PKS. After you deploy PKS, BOSH automatically deletes these VMs.

To enable PKS to dynamically create the ephemeral VMs when needed, ensure that the following resources are available in your vSphere infrastructure before deploying PKS:

Ephemeral VM Number CPU Cores RAM Ephemeral Disk
BOSH Compilation VMs 4 4 4 GB 16 GB

Kubernetes

Each Kubernetes cluster provisioned through 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 10 GB
errand (ephemeral) 1 1 1 GB 8 GB none

NSX-T

Deploying NSX-T requires the additional following resources from your vSphere environment:

NSX-T Component Instance Count Memory per Instance vCPU per Instance Disk Space per Instance
NSX Manager Appliance 1 16 GB 4 140 GB
NSX Controllers 3 16 GB 4 120 GB
NSX-T Edge 1 up to 8 16 GB 8 120 GB

Firewall Requirements

For the firewall ports and protocols requirements for using PKS on vSphere with NSX-T integration, see Firewall Ports and Protocols Requirements.

Other Requirements

Note: When you use NSX-T 2.1, creating namespaces with names longer than 40 characters may result in a truncated or hashed name in the NSX-T Manager UI.
