Loyalty App

This application serves as a demo app for Technical Marketing. The application helps fictional customers sign up for a loyalty program at the fictional company Hard Top Hotels.

Purpose

The purpose of this application is to have a sample app to use for demonstrations. During demos/blog posts/webinars, etc this app can be deployed on virtual machines, or through containers to be used for migration purposes, backup/restore demonstrations, or app deconstruction.

Architecture

This application has two parts associated with it.

  1. The golang web server
  2. A mongo database to store “loyalist” information.

Deployment

Deployment – Kubernetes

There are manifests in the kubernetes directory to deploy a prebuilt image.

NOTE: In order to use the existing manifests, you’ll need a Kubernetes cluster with a cloud provider capable of creating load balancers. If you need a bare metal load balancer there are manifests in the metal-lb folder.

You can deploy all of the kubernetes components by deploying each of the yaml manifests in the kubernetes folder. There is also an option to deploy with letsencrypt certificates if you can use cert-manager with letsencrypt in your environment.

  1. Configure your kubectl to use a KUBECONFIG file with access to your Kubernetes cluster.
  2. Update the credentials in the deployment YAML to match your database.
  3. Deploy the manifests within the Kubernetes folder in sequential order.
  4. Set a DNS entry to match your loyalty service endpoint. This should be the entry in the virtualhost config in the loyalty app manifest.

Deployment – DocumentDB

The Loyalty App can be deployed while using the Amazon DocumentDB service.

Kubernetes Deployment

If you’re deloying Loyalty App through Kubernetes, the Loyalty Manifest must have the MONGO_TLS value set to a non nil value. When the application starts up with a non-nil value, it appends the AWS Certificate details to the connection string. The certificate is included in the image build.
