Installing Tanzu Kubernetes Grid Integrated Edition Manually

If you are installing Tanzu Kubernetes Grid Integrated Edition manually, do the following before deploying Tanzu Kubernetes Grid Integrated Edition:

1. Review Resource Requirements below.
2. Install and configure Ops Manager. To install and configure Ops Manager, follow the instructions in Installing and Configuring Ops Manager on GCP.
3. Create service accounts for Kubernetes master and worker nodes. To create the service accounts, follow the instructions in Creating Service Accounts in GCP for Tanzu Kubernetes Grid Integrated Edition.

   Note: Perform this step after you install and configure Ops Manager.

4. Create a load balancer to access the TKGI API from outside the network and run tkgi commands from your local workstation. To create a load balancer in GCP, follow the instructions in Creating a GCP Load Balancer for the TKGI API.

   Note: Perform this step before you install Tanzu Kubernetes Grid Integrated Edition. After you install Tanzu Kubernetes Grid Integrated Edition, you must complete the load balancer configuration. To complete the load balancer configuration, do the procedure in Create a Network Tag for the Firewall Rule.

Installing Tanzu Kubernetes Grid Integrated Edition Using Terraform

If you are installing Tanzu Kubernetes Grid Integrated Edition using Terraform, do the following before deploying Tanzu Kubernetes Grid Integrated Edition:

1. Review Resource Requirements below.
2. Install and configure Ops Manager. To install and configure Ops Manager, follow the instructions in Installing and Configuring Ops Manager on GCP.

Resource Requirements

Installing Ops Manager and Tanzu Kubernetes Grid Integrated Edition requires the following virtual machines (VMs):

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:

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.
