Learn Terraform - Provision a GKE Cluster

This repo is a companion repo to the Provision a GKE Cluster learn guide, containing Terraform configuration files to provision an GKE cluster on GCP.

This sample repo also creates a VPC and subnet for the GKE cluster. This is not required but highly recommended to keep your GKE cluster isolated.

The steps I did

1. Clone the repository learn-terraform-provision-gke-cluster
2. Downgrade my terraform to the same version in versions.tf
   • run: rm -r $(which terraform)
   • install wget: brew install wget
   • install the right version using wget: wget https://releases.hashicorp.com/terraform/0.14.11/terraform_0.14.11_darwin_amd64.zip
   • then unzip the file: unzip terraform_0.14.11_darwin_amd64.zip
   • move the executable file to local mv terraform /usr/local/bin/terraform
   • finally terraform --version gives Terraform v0.14.11

You wouldn't be able to run the terraform init if you don't have the desired version, you will run into other issues, that you wouldn't enjoy

3. Initialize terraform: terraform init
4. You need to setup your google cloud application default credential by running gcloud auth application-default login and login with the right account. Otherwise terraform will not be able to run the apply
5. By runnning terraform apply would gives you an idea about the numbe of resources will be applied, and don't forget to enable Kubernetes Engine API in your google cloud

This basic project, will create vpc and subnet for GKE cluster, Plus creating the GKE cluster name and host.
