Distributed Tracing demo for Azure

This is a draft of distributed tracing demo app demonstrating Azure SDKs and OpenTelemetry integration.

Prerequisites

You'll need Azure subscription and resources
- EventHub
- Storage
- ApplicationInsights resource if you're running it with Azure Monitor
Docker

Getting started

Create .env file with access keys to resources content:

EVENTHUB_CONNECTION_STRING= <event hub connection string, no entity name here>
EVENTHUB_NAME= <event hub name>
CHECKPOINT_STORAGE_ACCESS_KEY= <storage access key>
CHECKPOINT_STORAGE_ACCOUNT= <storage account name for checkpointing>
CHECKPOINT_CONTAINER_NAME= <storage container name for checkpointin>
CHECKPOINT_STORAGE_CONNECTION_STRING= <Full storage connection string for checkpointing, sorry>

If you're running it with Azure Monitor, please also add

APPINSIGHTS_INSTRUMENTATIONKEY= <your app insights key>

Run demo with docker-compose -f docker-compose_applicationinsights.yml up --build (for AzureMonitor) or docker-compose_jaeger.yml (for Jaeger).

Exposed endpoints
