Overview

This repo shows a brief example of ytt templating.

Instructions

1. Obtain and target a Kubernetes Cluster.
2. Deploy the application to the cluster:

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

   Note: The values from config/ are applied first and the production values from env/ will override them.
3. Forward local traffic to the cluster in order to visit the app:

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

4. Verify the deployment

$ curl localhost:8080/app/
