vSphere Prerequisites and Resource Requirements
Page last updated:
This topic describes the prerequisites and resource requirements for installing Pivotal Container Service (PKS) on vSphere.
For prerequisites and resource requirements for installing PKS on vSphere with NSX-T integration, see vSphere with NSX-T 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.
PKS on vSphere supports the following vSphere component versions:
*PKS v1.1.2 and later are compatible with vSphere 6.5 U2.
Installing Ops Manager and PKS requires the following virtual machines (VMs):
|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||32 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||50 GB|
|errand (ephemeral)||1||1||1 GB||8 GB||none|
