Kubernetes Engine Example

Example showing how to integrate the Terraform kubernetes provider with a Google Kubernetes Engine cluster.

Change to the example directory

[[ `basename $PWD` != example-gke-k8s-service-lb ]] && cd example-gke-k8s-service-lb

Install Terraform

1. Install Terraform if it is not already installed (visit terraform.io for other distributions):

../terraform-install.sh

Set up the environment

1. Set the project, replace YOUR_PROJECT with your project ID:

PROJECT=YOUR_PROJECT

gcloud config set project ${PROJECT}

2. Configure the environment for Terraform:

[[ $CLOUD_SHELL ]] || gcloud auth application-default login
export GOOGLE_PROJECT=$(gcloud config get-value project)

Run Terraform

terraform init
terraform apply

Testing

1. Wait for the load balancer to be provisioned:

./test.sh

2. Verify response from load balancer:

curl http://$(terraform output load-balancer-ip)

Connecting with kubectl

1. Get the cluster credentials and configure kubectl:

gcloud container clusters get-credentials $(terraform output cluster_name) --zone $(terraform output cluster_zone)

2. Verify kubectl connectivity:

kubectl get pods -n staging

Cleanup

1. Delete resources created by terraform:

terraform destroy
