minikube-echoserver

Example of running echoserver on minikube using pure terraform

Prerequisites

• Terraform > 0.12
• minikube > 1.5.2

Steps:

1. Start minikube: minikube start
2. Clone repo: git clone git@github.com:jhole89/terraform-k8s-example.git
3. Change to this directory: cd minikube-echoserver
4. Initialise terraform: terraform init
5. Apply terraform plan: tf apply --auto-approve - you should see the following output

   kubernetes_namespace.example_namespace: Creating...
   kubernetes_namespace.example_namespace: Creation complete after 0s [id=example-app-namespace]
   kubernetes_deployment.example_deployment: Creating...
   kubernetes_deployment.example_deployment: Creation complete after 5s [id=example-app-namespace/example-app-deployment]
   kubernetes_service.example_service: Creating...
   kubernetes_service.example_service: Creation complete after 1s [id=example-app-namespace/example-app-service]
   
   Apply complete! Resources: 3 added, 0 changed, 0 destroyed.
   
   Outputs:
   
   node_port = 31740
   

6. The plan outputs the node_port exposed through the kubernetes service (here it was 31740). You can now hit the endpoint using curl: curl $(minikube ip):31740
7. Once no longer required you can remove all resources: terraform destroy --auto-approve
8. Stop minikube: minikube stop
