This example shows a simple two tier setup in Kubernetes, and simply prints the environment information that each pod sees. Querying the service multiple times will show services at work load balancing requests.
Building
For each container, the build steps are the same. The examples below
are for the show container. Replace show with backend for the
backend container.
GCR
docker build -t gcr.io/<project-name>/show .
gcloud preview docker push gcr.io/<project-name>/show
Docker Hub
docker build -t <username>/show .
docker push <username>/show
Change Pod Definitions
Edit both show-rc.yaml and backend-rc.yaml and replace the
specified image: with the one that you built.
