Open-census instrumentation with golang web service to gather distributed traces

Service A ------(sends request to)------> Service B

Simultaneously capture and export traces to oc-collector. Oc-collector sends the traces to jaeger tracing backend (jaeger-all-in-one) traces are visualised using Jaeger dashboard running on localhost:16686

Docker compose to spin up

1. jaeger-all-in-one container Exposes port 16686 to view dashboard. port 14268 to receive trace data
2. oc-collector Exposes 55678 port to receive trace data from golang microservices
3. golang service A POST /hello-service-A endpoint {"sender":"XYZ"}
4. golang service B POST /hello-service-B endpoint {"sender":"XYZ" , "message": "hi !"}

Steps

1. cd to project root directory
2. Run the following command docker-compose up
3. Open browser and hit localhost:16686 to see the traces
