Azure Prerequisites and Resource Requirements

Page last updated:

This topic describes the prerequisites and resource requirements for installing Enterprise Pivotal Container Service (Enterprise PKS) on Microsoft Azure.

Prerequisites

Before you install Enterprise PKS, you must do the following:

  • Meet Azure subscription requirements. See Subscription Requirements below.
  • Install one of the following:

    • Ops Manager v2.4.2, v2.4.3 or v2.4.13
    • Ops Manager v2.5.5 or later
    • Ops Manager v2.6.x

For more information, see Install and Configure Ops Manager below.

Subscription Requirements

For Enterprise PKS and Kubernetes services to run correctly, you must have at least a standard subscription tier.

Install and Configure Ops Manager

Note: You use Ops Manager to install and configure Enterprise PKS. Each version of Ops Manager supports multiple versions of Enterprise PKS. To confirm that your Ops Manager version supports the version of Enterprise PKS that you install, see Enterprise PKS Release Notes.

Note: The topics below provide the Terraform procedures for deploying Ops Manager on Azure, not the manual procedures. The Terraform procedures are the currently supported path for deploying Ops Manager on Azure for use with Enterprise PKS.

To install a compatible Ops Manager version, follow the instructions in the table below:

Version
Ops Manager 2.4
  1. Preparing to Deploy Ops Manager on Azure Using Terraform
  2. Deploying Ops Manager on Azure Using Terraform
  3. Configuring BOSH Director on Azure Using Terraform
Ops Manager 2.5
  1. Preparing to Deploy Ops Manager on Azure Using Terraform
  2. Deploying Ops Manager on Azure Using Terraform
  3. Configuring BOSH Director on Azure Using Terraform
Ops Manager 2.6
  1. Preparing to Deploy Ops Manager on Azure Using Terraform
  2. Deploying Ops Manager on Azure Using Terraform
  3. Configuring BOSH Director on Azure Using Terraform

Resource Requirements

Installing Ops Manager and Enterprise 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 120 GB
BOSH Director 2 8 GB 16 GB

Storage Requirements for Large Numbers of Pods

If you expect the cluster workload to run a large number of pods continuously, then increase the size of persistent disk storage allocated to the the Pivotal Container Service VM as follows:

Number of Pods Storage (Persistent Disk) Requirement ^*
1,000 pods 20 GB
5,000 pods 100 GB
10,000 pods 200 GB
50,000 pods 1,000 GB

Kubernetes Cluster Resources

Each Kubernetes cluster provisioned through Enterprise 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
