LATEST VERSION: v1.1 - RELEASE NOTES
Pivotal Container Service v1.1

vSphere Prerequisites and Resource Requirements

Page last updated:

This topic describes the prerequisites and resource requirements for installing Pivotal Container Service (PKS) on vSphere with or without NSX-T integration.

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 the VMware Harbor Registry documentation.

Component Version Requirements

vSphere Version Requirements

PKS on vSphere supports the following vSphere component versions:

Versions Editions
  • VMware vSphere 6.5 U2
  • VMware vSphere 6.5 U1
  • VMware vSphere 6.5 GA
  • vSphere Enterprise Plus
  • vSphere with Operations Management Enterprise Plus

NSX-T Integration Component Version Requirements

Deploying NSX-T requires the additional following component versions:

Component Version
VMware NSX-T 2.1 Advanced edition

Resource Requirements

Installing PKS deploys the following two virtual machines (VMs):

VM CPU RAM Storage
Pivotal Container Service 1 4 GB 20 GB
Pivotal Ops Manager 1 8 GB 160 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

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 Integration Resource Requirements

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
