A simple web app written in Go that you can used for testing.

• A Kubernetes cluster
• Docker installed and running on a machine, and a Docker Hub or private repository account configured.

1. Use Docker to build the sample code into a container.

   # Build the container on your local machine
   docker build -t <image-tag> .
   
   # Push the container to docker registry
   docker push <image-tag>

2. After the build has completed and the container is pushed to docker registry, you can deploy the app into your cluster. Make sure the container image value in helloworld-go-v1.yaml matches the <image-tag> you built in the previous step. Apply the configuration using kubectl:

   kubectl apply -f helloworld-go-v1.yaml

To remove the sample app from your cluster, delete the service record:

kubectl delete -f helloworld-go-v1.yaml
