Udagram Image Filtering Application

Udagram is a simple cloud application developed alongside the Udacity Cloud Developer Nanodegree. It allows users to register and log into a web client, post photos to the feed, and process photos using an image filtering microservice.

The project is split into two parts:

• Frontend: Angular web application built with Ionic Framework.
• Backend RESTful API: Node-Express application.

Service Orchestration with Kubernetes

1. Deploying Microservices on AWS using Kubernetes

   • The microservices are successfully deployed on a Kubernetes cluster.
   • The output of kubectl get pods indicates that the pods are running successfully with the STATUS value Running.

   

2. Service Descriptions

   • The output of kubectl describe services confirms that no sensitive information such as database passwords is exposed.
