Create GKE cluster with Terraform

In this Article I will show about how to create GKE Cluster with Terraform

Objective

• Create GKE cluster
• Access GKE Cluster

Create GKE cluster

you can create GKE Cluster with GUI. but in this example I will use terraform to create GKE Cluster

git clone https://github.com/dounpct/terraform-gke-test.git

• edit terraform.tfvars for your project and gke information

project_id      = "project-test"
region          = "asia-southeast1"
zone            = "asia-southeast1-a"
cluster_name    = "terraform-cluster-01"

vpc_name    = "project-test-terraform-cluster-01-vpc"
vpc_subnet_name = "project-test-terraform-cluster-01-subnet"
vpc_subnet_range = "10.10.0.0/24"

machine_type = "n1-standard-2"
gke_num_nodes = 3

• set terraform backend in versions.tf in this example I keep state in GCS (google cloud storage). if you would like to keep state in you local machine. you can remove backend

terraform {
  backend "gcs" {
    bucket  = "gcp-dmp-devops-terraform-state"
    prefix  = "jiw-terraform-state/terraform-cluster-01"
  }
}

# authen gcp
    export GOOGLE_APPLICATION_CREDENTIALS="path-to-your-google-service-account-key/key.json"
# apply terraform
    terraform init
    terraform apply

Access GKE Cluster

• copy Command-line access

• paste in you terminal

gcloud container clusters get-credentials terraform-cluster-01 --zone asia-southeast1-a --project project-test

kubectl get nodes -o wide
