Architecture

The application is made up of the following components:

• Namespace
• Deployment
  • MongoDB Pod
    • DB Authentication configured
    • Attached to a PVC
  • Pac-Man Pod
    • Nodejs web front end that connects back to the MongoDB Pod by looking for the Pod DNS address internally.
• RBAC Configuration for Pod Security and Service Account
• Secret which holds the data for the MongoDB Usernames and Passwords to be configured
• Service
  • Type: ClusterIP
• Ingress
  • Using a certificate generated via certman

Source

These are modified files from the below github repos , changed mildly to make them run contained in a single namespace and without priviledged pods.
