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).
To install PKS, you must deploy Ops Manager v2.2.2 and later or v2.3.1 and later. You use Ops Manager to install and configure PKS. See the PKS Release Notes to confirm that your Ops Manager version supports PKS.
You must also create service accounts for Kubernetes master and worker nodes and create a load balancer to access the PKS API.
To install and configure Ops Manager, follow the procedures in the Ops Manager documentation:
Note: Multiple versions of Ops Manager support each version of PKS. Choose an Ops Manager version that supports the PKS version you intend to install and follow the procedures in the corresponding version of the Ops Manager documentation.
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
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 PKS deploys 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|
