GCP Prerequisites and Resource Requirements
Page last updated:
This topic describes the prerequisites and resource requirements for installing Pivotal Container Service (PKS) on Google Cloud Platform (GCP).
Before you install PKS, you must install one of the following:
- Ops Manager v2.3.1 or later
- Ops Manager 2.4.x
Note: You use Ops Manager to install and configure PKS. Each version of Ops Manager supports multiple versions of PKS. To confirm that your Ops Manager version supports the version of PKS that you install, see PKS Release Notes.
You must also create service accounts for Kubernetes master and worker nodes and create a load balancer to access the PKS API.
To install an Ops Manager version that is compatible with the PKS version you intend to use, follow the instructions in the corresponding version of the Ops Manager documentation.
Note: The topics below provide the manual procedures for deploying Ops Manager on GCP, not the Terraform procedures. The manual procedures are the currently supported path for deploying Ops Manager on GCP for use with PKS.
|Ops Manager v2.3|
|Ops Manager v2.4|
After you install and configure Ops Manager, you must create service accounts for Kubernetes master and worker node VMs in your PKS deployment. To create the service accounts, follow the procedures in Creating Service Accounts in GCP for PKS.
Before you install PKS, you must create an external TCP load balancer so that you can access the
PKS API from outside the network. This load balancer allows you to run
pks commands from your
local workstation. You must create the load balancer before you install PKS, and then complete the
load balancer configuration after you install PKS.
To create a load balancer in GCP, follow the procedures in Creating a GCP Load Balancer for the PKS API.
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 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 Name||Number||CPU Cores||RAM||Ephemeral Disk||Persistent Disk|
|master||1||2||4 GB||32 GB||5 GB|
|worker||1||2||4 GB||32 GB||50 GB|
