This repository contains a simple application written in .net core that runs on Linux container on Azure Kubernetes Service and uses LinkerD service mesh to demonstrate the service mesh proxies that intercept gRPC inter-service calls, deploying mTLS, observability etc.

There are 3 services in this app.

• Web interface
• Backend service
• Daemon service

Continuously collects COVID-19 updates from public APIs and relay them to the Backend service. Also raises Azure SignalR notifications for Live cases.

Receives information from Daemon service and caches them in memory collections.

Only talks to the backend service and fetches data every 5 seconds and displays them into the UI. Also received live updates from Azure SignalR and shows them in a Azure map.

The Azure pipeline (azure-pipeline.yml) has all the necessary commands that will create a AKS cluster, install LinkerD on it and then build the docker images for 3 services, push them in Docker public registry and then deploy them to AKS.

To run locally, you can execute the bash files, specially buildimages.sh and deploy-to-aks.sh.
