Using TMC CLI to create a TKG AWS production cluster

Products

• VMware Tanzu Kubernetes Grid

Issue/Introduction

To create a Production grade TKG AWS Workload cluster, we need to pass a yaml with the necessary data to TMC CLI.

Resolution

TMC CLI should point to a yaml as show below

tmc cluster create -f <configfile>

Example:  

tmc cluster create -f ~/Downloads/prod-aws-config.yaml
√ cluster "prod-aws-cluster" is being created

Example config file below. The values inside the Cluster Spec can be changed, while making sure there are three Nodepools specified. 

The three Nodepools should have AZs in the same order as the  AZs  specified in the provider subnet section.
