Use this repo as an example for organizing ytt templates within your application repo

Overview

Use this repo as an example for organizing ytt templates for your application.

Directory structure

• config/ contains files describing app configuration
• config-env/ contains environment configuration files
• Dockerfile

Instructions

1. Obtain and target a Kubernetes Cluster.

2. Deploy the application to the cluster:

   $ ytt -f config/ -f config-env/production.yml | kubectl apply -f -
   deployment.apps/greeter created
   service/greeter created
   configmap/greeter created

   Note: The values from config/ are applied first and the production values from config-env/ will override them.

3. Forward local traffic to the cluster in order to visit the app:

   $ kubectl port-forward service/greeter 8080:8080
   Forwarding from 127.0.0.1:8080 -> 80
   Forwarding from [::1]:8080 -> 80

4. Verify the deployment

   $ curl localhost:8080/app/
