Azure Prerequisites and Resource Requirements
Page last updated:
This topic describes the prerequisites and resource requirements for installing Pivotal Container Service (PKS) on Microsoft Azure.
Before you install PKS, you must satisfy Azure subscription requirements and install one of the following:
- Ops Manager v2.4.3 and earlier in the v2.4 version line
- Ops Manager v2.3.9 and earlier in the v2.3 version line
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.
For PKS and Kubernetes services to run correctly, you must have at least a
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 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 PKS.
|Ops Manager v2.3|
|Ops Manager v2.4|
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||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 ResourcesEach 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|
