Create a GKE Cluster on the Google Cloud Platform using Terraform
Google Kubernetes Engine (GKE) is a managed Kubernetes service offered by Google Cloud Platform (GCP), simplifying containerized applications’ management and deployment. This tutorial will guide you through creating a GKE cluster using Terraform, a widespread Infrastructure as Code (IaC) tool.

Set up the Terraform Configuration
First, create a new directory for your Terraform configuration:
main.tf file in the
gke-terraform directory and add the following code:
<PATH_TO_YOUR_SERVICE_ACCOUNT_KEY_JSON> with the path to your GCP service account key JSON file,
<YOUR_PROJECT_ID> with your GCP project ID, and
<YOUR_REGION> with your desired GCP region.
gke-terraform directory, run the following command to initialize Terraform:
This command downloads the required provider plugins and sets up the backend for storing your Terraform state.
Create the GKE Cluster
Run the following command to create the GKE cluster:
Type “yes” when prompted to confirm that you want to create the resources. The resource creation process may take several minutes to complete. Once done, Terraform will output the cluster endpoint and cluster CA certificate.
Connect to the GKE Cluster
Save the kubeconfig output from the previous step to a file, and set the
KUBECONFIG environment variable to use it:
Now, you can use kubectl to interact with your GKE cluster:
This command will show the nodes in your GKE cluster.
Clean Up Resources
When you no longer need the GKE cluster, you can destroy the resources using Terraform:
Type “yes” when prompted to confirm that you want to destroy the resources.
This tutorial taught you how to create a Google Kubernetes Engine (GKE) cluster using Terraform on the Google Cloud Platform. By leveraging Infrastructure as Code, you can maintain consistent environments, collaborate with your team more effectively, and automate the provisioning and management of your Kubernetes clusters.
With your GKE cluster up and running, you can now deploy containerized applications, scale your infrastructure, and take advantage of the many features offered by GCP and Kubernetes. To dive deeper into GKE and Terraform, explore the official GKE documentation and the Terraform Google provider documentation.
