This topic describes the prerequisites and resource requirements for installing VMware Tanzu Kubernetes Grid Integrated Edition (TKGI) on Microsoft Azure.
Prerequisites
Before installing Tanzu Kubernetes Grid Integrated Edition:
-
Review the sections below.
-
Install and configure Ops Manager. To install Ops Manager, follow the instructions in Installing and Configuring Ops Manager on Azure.
Subscription Requirements
For Tanzu Kubernetes Grid Integrated Edition and Kubernetes services to run correctly, you must have at least a standard subscription tier.
Resource Requirements
Installing Ops Manager and Tanzu Kubernetes Grid Integrated Edition requires the following virtual machines (VMs):
| VM | CPU | Memory (GB) | Ephemeral Disk (GB) |
|---|---|---|---|
| BOSH Director | 2 | 8 | 16 |
| Ops Manager | 1 | 8 | 120 |
| TKGI API | 2 | 8 | 64 |
| TKGI Database | 2 | 8 | 64 |
NOTE: VMware recommends deploying TKGI on its own dedicated Ops Manager instance, rather than on a shared Ops Manager that also hosts other runtimes such as Tanzu Application Service.
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 TKGI Database VM as follows:
| Number of Pods | Persistent Disk Requirements (GB) |
|---|---|
| 1,000 pods | 20 |
| 5,000 pods | 100 |
| 10,000 pods | 200 |
| 50,000 pods | 1,000 |
Kubernetes Cluster Resources
Each Kubernetes cluster provisioned through Tanzu Kubernetes Grid Integrated Edition deploys the VMs listed below. If you deploy more than one Kubernetes cluster, you must scale your allocated resources appropriately.
| VM | VM Count | CPU Cores | Memory (GB) | Ephemeral Disk (GB) | Persistent Disk (GB) |
|---|---|---|---|---|---|
| Control Plane | 1 | 2 | 4 | 32 | 5 |
| Worker | 1 | 2 | 4 | 32 | 50 |
