Create an Google Cloud Platform Cluster

Pre-requisites

This assumes that you already have a Google Cloud Platform account and have created and selected a project with the necessary services enabled

• Install Google Cloud SDK
• Install kubectl command line tool

Create Google Cloud Platform SDK config

gcloud init
gcloud auth application-default login

Create GCP GKE Cluster

Option 1: Create using command line tools (locally)

• Create the Kubernetes cluster (this will take a few minutes)

gcloud container clusters create <cluster-name> --cluster-version=1.16 \
  --num-nodes=30 \
  --no-enable-autoupgrade
  --enable-autoscaling
  --min-nodes 15 
  --max-nodes 50

• After the cluster has completed, verify that there are 3 nodes running:

gcloud compute instances list

• Generate a kubeconfig entry that uses gcloud for authentication

gcloud container clusters get-credentials <cluster-name> --zone <zone> --project <project>

---

Option 2: Create GKE cluster using Terraform

• Download and Install the Terraform CLI

Clone the cluster-baseline repository:

git clone git@github.com:CloudNativeGBB/cluster-baseline.git
cd cluster-baseline/infrastructure/gcp

• Verify that Terraform is >= 0.13.2

terraform version

• Open terraform.tfvars and replace the default values with your project_id, region, and cluster_name

• Initialize Terraform

terraform init

• To see any changes in advance that are required for your infrastructure, use terraform plan.

• Create the cluster using Terraform templates

terraform apply

• Generate a kubeconfig entry that uses gcloud for authentication

gcloud container clusters get-credentials <cluster-name> --zone <zone> --project <project>
