This repository contains the Terraform module for creating a simple but ready-to-use Kubernetes Cluster on Google Cloud Kubernetes Engine (GKE).

It uses the latest available Kubernetes version available in the Google Cloud location and creates a kubeconfig file at completion.

You need a Google Cloud account with billing enabled (if you already exceeded the Trial).

• Always uses latest Kubernetes version available at Google Cloud location
• kubeconfig file generation
• Master nodes are available from workstation IP address only (master_authorized_networks_config)
• Create zonal (default) or regional GKE cluster (enable_regional_cluster)

• export KUBECONFIG=./kubeconfig_gke in repo root dir to use the generated kubeconfig file
• If you want to create a regional cluster set enable_regional_cluster to true (keep in mind that number of gke_nodes will be deployed in every zone - e.g. 3 zones in a region * 2 gke_nodes => 6 worker nodes)
• The enable_google variable is used in the hajowieland/terraform-kubernetes-multi-cloud module

See tables at the end for a comprehensive list of inputs and outputs.

• Default region: europe-west3 (Frankfurt, Germany)
• Default node type: n1-standard-2 (1x vCPU, 7.5GB memory)
• Default node pool size: 2
